Vol 49 No 2 Mar-April 2009 103 genera and 46 families is heartening indeed Their continuedexistence by and large indicates that these birds have one wayor another adapted to the severe environmental conditions ofBarmer District While a third of the birds recorded (56 species)were widespread residents 22 species were sparse localswhich go to show that they have adapted well to all the seasonsHowever a quarter of the species (43) were classified as wintervisitors or summer visitors or passage migrants Yet the statusof the remaining 27 species could not be ascertained
Obviously within the Great Thar Desert there are some intriguingbio-geographical riddles Conventional wisdom suggests thatthe birds do undertake local movements in response toseasonal variations in temperature or precipitation Mostspecies of arid drylands spend most of their time in foragingon the ground but they still require small bushes for protectionfrom predators and for nesting Nevertheless the most arid-adapted birds are found in Barmer Some species are found inareas as only winter visitors leaving by spring or early summerMovements associated with rainfall in arid areas may be moresporadic occurring either as local nomadism or as irruptionsoutside the normal range in exceptionally wet years as in 2006The district received 549 mm rain between 16 and 25 August ofthat year which resulted in the formation of 20 new lakes ofwhich 6 covered an area of over 10 km2
The tendency of some members of a family expanding their rangein wet years has been observed in many arid regions of the worldHowever other members of the family may undertake localmovements in order to exploit different habitats when not breeding
In Barmer some birds may be exhibiting winter-fidelity orOrtstreue In Ortstreue for example the desert Cisticolas (FlyCisticolidae) have been found to expand their range westwardin wet years in South Africa and Botswana Other members ofthe family preferred to undertake local movements in order toexploit different habitats when not breeding and atleast somespecies demonstrated winter site fidelity or Ortstreue In a studyin Malawi ringed Cisticolas visited the study area only for amonth or so at the end of their post-breeding moult two femaleswere caught at the same site for respectively four and fiveyears in succession Ortstreue also has been exhibited by otherCisticolas wintering on Gibraltar in south-west EuropeHowever we are not sure whether the Cisticolas of Barmaralso exhibit Ortstreue Only long-term systematic research canunravel the avian secrets surrounding the Thar Desert and themigratory adaptations of the desert birds
While the research on migration and local movements willcontinue to enlarge worldwide the pursuit of the theories of allmigration types including Ortstreue will move towards thecentre-stage This will mark the triumphant elevation of thescientific odyssey that began in the 1850s in India by thepioneering works of Hodgson Jerdon Blyth and later by thetireless efforts of A O Hume Blanford Oats and Stuart-BakerAn inspiring trend can be seen over the years in the steady flowof research articles for publication in our newsletter and I owea deep sense of gratitude to the authors for sharing their intenseobservations and invaluable data with our readers
Thanking youYours in bird conservation

Dear fellow Birdwatchers
Desert birds and their migratory adaptations
In this issue we have published an exclusive article Birds of
Barmer District Rajasthan India by P C Tak P L Kankane and
Padma Bohra of Zoological Survey of India Barmer District formsa part of the Great Indian Thar Desert The authors have observedand recorded the avifauna in the study area of c 850 sq km
Barmer district has only 060 forest cover which includes 12km2 of moderately dense forest and 157 km2 of open forestThe average rainfall in a year is 277mm only The variation intemperature in various seasons is quite high varying from 270
C to 430C during summer (often soaring to 480C) and from100C to 260C during winter (sometimes dropping to 50C) Onaccount of the harsh conditions conjoined with sparsevegetation scanty rainfall and blistering climate one mightpresume that the district will be bereft of birds save for a fewomnivores or carrion eaters
In an era when even common birds like the sparrows are beingphased out the presence of 153 species of birds belonging to

mm rain between August 16 and August 25 2006 left manydead and huge losses As many as 20 new lakes formedand 6 covered an area of over 10 km2
The district has two main seasonal rivers namely Luni Riverand Sukri River The former originates from the Nag hills ofAjmer flows through Jodhpur and Jalore districts flowingthrough the SE portion of Barmer and then it enters theadjoining southerly state of Gujarat and finally falls intoKachchh region (c 320 km long) Until the place of Balotarathe water of the Luni (Salty) is sweet but after that thewater becomes salty (Luni) The Sukri River flows from closeto Mount Abu of the Aravalli Range flows through the districtsof Sirohi Jalore and Barmer in Rajasthan and finally mergesinto the Luni River in district Barmer
The vegetation of the district is sparse and dry deciduoustype consisting of a small range of slow-growing thornytrees shrubs and grasses that has adapted itself to theharsh conditions The most commonly found tree speciesare the ubiquitous khejri (Prosopis cineraria) and varioustypes of acacia which are extremely drought resistantdue to their deep root system Another tree that dots thedistrict is the rohira (Tecoma undulata) The various shrubsoccurring being the phog (Calligonum polygonoides) khair(Capparis decidua) ak (Calotropis procera) and thor(Euphorbia caduca) While important grasses include thesewan (Lasiurus sindicus) dhaman (Cenchhrus ciliaris)boor (Cenchrus jwarancusa) and bharut (Cenchruscatharticus)
An analysis of the digital interpretation in terms of threedifferent canopy density class by the Forest Survey of IndiaDehra Dun reveals that of its total geographical area of 28387km2 the district Barmer has only 060 forest cover whichincludes 12 km2 of moderately dense forest (40-100) 157km2 of open forest and 00 of very dense forest (Anonymous2005)
Methodology
The present contribution is largely based on the recent fieldobservations made during three field visits (3-5 days each)in Kapurdi and Jalipa Lignite Mining areas of the districtBarmer in the year 2008 The field observations were spreadover three major seasons viz winter (January) summer(May) and monsoon (September) These observations havebeen supported by the indispensable works of Rahmani(1997) Sivaperuman et al (2005) and Kumar et al (2006)

Introduction
Barmer district lies in western part of Rajasthan It is a partof Thar Desert (or Great Indian Thar Desert) of Rajasthan Itis surrounded by the district Jaisalmer in the north Jalorein the south Pali and Jodhpur in the east and Pakistan inthe west (c 270 km)
Some information on avifauna of the district Barmer iscontributed by Rahmani (1997) Sivaperuman et al (2005)and Kumar et al (2006) Rahmani (1997) stated that theThar has high avian diversity of nearly 250 species He alsoprovided detailed notes for 213 species which he identifiedduring his surveys (nearly half being non-desert taxa)including 35 species of birds from Barmer district LaterSivaperuman et al (2005) while dealing with avian diversityof 271 species and district-wise distribution of birds in 13districts of the Thar Desert of Rajasthan provided a list of91 bird species for Barmer district Subsequently Kumar etal (2006) in their Geo-spatial Atlas for the Wetland Birdsof Thar Desert Rajasthan made a mention of 53 species of
wetland birds from the district Barmer
Similarly last year when we got an opportunity to undertakethe General Faunistic Surveys (one of the primary objectives
of the Zoological Survey of India) for an Impact Assessment
of the proposed Lignite Mining on Fauna in Kapurdi andJalipa Blocks and surrounding zone of 10 km radius ofBarmer district (Rajasthan) we also maintained a separate
record of the birds we observed and recorded in the studyarea of c 850 sq km This resulted in to a total of 60 speciesof birds
As there is no exclusive bird list for the district Barmer itwas considered worthwhile to compile all these foregoingscattered bird lists and prepare a comprehensive birdchecklist for the district Barmer The present checklist ofbirds deals with a total of 153 species belonging to 103genera and 46 families (Table)
Study area
The district Barmer covers a total area of 28387 km2 and islocated at an altitude of 226 meters between the coordinates240-270 N and 700-730 E The variation in temperature invarious seasons is quite high Usually the temperature variesfrom 270 C to 430C during summer (may soar to 460C to480C) and from 100C to 260C during winter (sometimes itdrops to 50C) Primarily the district is a desert where averagerainfall in a year is 277mm However extreme rainfall of 549

The nomenclature and systematic sequence of birds as givenby Manakadan amp Pittie (2001) has been followed Theidentification of birds and information on their residentialstatus basic food habits etc is based on Ali amp Ripley (1968-78) Grimmett et al (1998) Kazmierczak (2000) and Kumaret al (2005) The conservation status presented here is asassigned by IUCN (2007) BNHS (2002) and Jhunjhunwalaet al (2001)
Analysis and Results
A total of 153 species of birds belonging to 103 genera and46 families have so far been recorded from the districtBarmer It constitutes about 42 of the avian diversity of364 species of birds (Idris et al 2009) known from TharDesert of Rajasthan Interestingly of these 153 species ofbirds 59 are water birds (Table)
The family-wise analysis indicates that family Muscicapidae-the most dominant family- leads the scene with 14 speciesfollowed by Anatidae- Ducks and Geese (12 species)Accipitridae- Vulture amp Eagles and Scolopacidae- Sandpipersamp Stints (10 each) Ardeidae- Heron amp Egrets (8) Alaudidae-Larks (7) Motacil l idae- Wagtails amp Pipits (6) andCharadriidae- Plovers amp Lapwings and Sturnidae- Starlingsamp Mynas (5 each) and so on (Table)
The following 15 species are listed under various threatcategories (3 CR 1 EN 4 VU amp 7 NT) by IUCN 2007 (Table)

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

FIRST SIGHTING OF COMMON SHELDUCK (Tadornatadorna) AND GREATER SCAUP (Aythya marila) ATDEEPOR BEEL ONLY RAMSAR SITE OF ASSAMDIPANKAR LAHKAR PG Dept of Wildlife and ConservationBiology North Orissa University Baripada Orissa- 757003d i p a n k a r l a h k a r g m a i l c o m LAKHAN TERON Natu ra l is t Aaranyak andBISWAJIT BARUAH PG Dept of Wildlife and ConservationBiology North Orissa University Baripada Orissa- 757003
Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

Vol 49 No 2 Mar-April 2009 103 genera and 46 families is heartening indeed Their continuedexistence by and large indicates that these birds have one wayor another adapted to the severe environmental conditions ofBarmer District While a third of the birds recorded (56 species)were widespread residents 22 species were sparse localswhich go to show that they have adapted well to all the seasonsHowever a quarter of the species (43) were classified as wintervisitors or summer visitors or passage migrants Yet the statusof the remaining 27 species could not be ascertained
Obviously within the Great Thar Desert there are some intriguingbio-geographical riddles Conventional wisdom suggests thatthe birds do undertake local movements in response toseasonal variations in temperature or precipitation Mostspecies of arid drylands spend most of their time in foragingon the ground but they still require small bushes for protectionfrom predators and for nesting Nevertheless the most arid-adapted birds are found in Barmer Some species are found inareas as only winter visitors leaving by spring or early summerMovements associated with rainfall in arid areas may be moresporadic occurring either as local nomadism or as irruptionsoutside the normal range in exceptionally wet years as in 2006The district received 549 mm rain between 16 and 25 August ofthat year which resulted in the formation of 20 new lakes ofwhich 6 covered an area of over 10 km2
The tendency of some members of a family expanding their rangein wet years has been observed in many arid regions of the worldHowever other members of the family may undertake localmovements in order to exploit different habitats when not breeding
In Barmer some birds may be exhibiting winter-fidelity orOrtstreue In Ortstreue for example the desert Cisticolas (FlyCisticolidae) have been found to expand their range westwardin wet years in South Africa and Botswana Other members ofthe family preferred to undertake local movements in order toexploit different habitats when not breeding and atleast somespecies demonstrated winter site fidelity or Ortstreue In a studyin Malawi ringed Cisticolas visited the study area only for amonth or so at the end of their post-breeding moult two femaleswere caught at the same site for respectively four and fiveyears in succession Ortstreue also has been exhibited by otherCisticolas wintering on Gibraltar in south-west EuropeHowever we are not sure whether the Cisticolas of Barmaralso exhibit Ortstreue Only long-term systematic research canunravel the avian secrets surrounding the Thar Desert and themigratory adaptations of the desert birds
While the research on migration and local movements willcontinue to enlarge worldwide the pursuit of the theories of allmigration types including Ortstreue will move towards thecentre-stage This will mark the triumphant elevation of thescientific odyssey that began in the 1850s in India by thepioneering works of Hodgson Jerdon Blyth and later by thetireless efforts of A O Hume Blanford Oats and Stuart-BakerAn inspiring trend can be seen over the years in the steady flowof research articles for publication in our newsletter and I owea deep sense of gratitude to the authors for sharing their intenseobservations and invaluable data with our readers
Thanking youYours in bird conservation

Note from the Publisher
Dear fellow Birdwatchers
Desert birds and their migratory adaptations
In this issue we have published an exclusive article Birds of
Barmer District Rajasthan India by P C Tak P L Kankane and
Padma Bohra of Zoological Survey of India Barmer District formsa part of the Great Indian Thar Desert The authors have observedand recorded the avifauna in the study area of c 850 sq km
Barmer district has only 060 forest cover which includes 12km2 of moderately dense forest and 157 km2 of open forestThe average rainfall in a year is 277mm only The variation intemperature in various seasons is quite high varying from 270
C to 430C during summer (often soaring to 480C) and from100C to 260C during winter (sometimes dropping to 50C) Onaccount of the harsh conditions conjoined with sparsevegetation scanty rainfall and blistering climate one mightpresume that the district will be bereft of birds save for a fewomnivores or carrion eaters
In an era when even common birds like the sparrows are beingphased out the presence of 153 species of birds belonging to

mm rain between August 16 and August 25 2006 left manydead and huge losses As many as 20 new lakes formedand 6 covered an area of over 10 km2
The district has two main seasonal rivers namely Luni Riverand Sukri River The former originates from the Nag hills ofAjmer flows through Jodhpur and Jalore districts flowingthrough the SE portion of Barmer and then it enters theadjoining southerly state of Gujarat and finally falls intoKachchh region (c 320 km long) Until the place of Balotarathe water of the Luni (Salty) is sweet but after that thewater becomes salty (Luni) The Sukri River flows from closeto Mount Abu of the Aravalli Range flows through the districtsof Sirohi Jalore and Barmer in Rajasthan and finally mergesinto the Luni River in district Barmer
The vegetation of the district is sparse and dry deciduoustype consisting of a small range of slow-growing thornytrees shrubs and grasses that has adapted itself to theharsh conditions The most commonly found tree speciesare the ubiquitous khejri (Prosopis cineraria) and varioustypes of acacia which are extremely drought resistantdue to their deep root system Another tree that dots thedistrict is the rohira (Tecoma undulata) The various shrubsoccurring being the phog (Calligonum polygonoides) khair(Capparis decidua) ak (Calotropis procera) and thor(Euphorbia caduca) While important grasses include thesewan (Lasiurus sindicus) dhaman (Cenchhrus ciliaris)boor (Cenchrus jwarancusa) and bharut (Cenchruscatharticus)
An analysis of the digital interpretation in terms of threedifferent canopy density class by the Forest Survey of IndiaDehra Dun reveals that of its total geographical area of 28387km2 the district Barmer has only 060 forest cover whichincludes 12 km2 of moderately dense forest (40-100) 157km2 of open forest and 00 of very dense forest (Anonymous2005)
Methodology
The present contribution is largely based on the recent fieldobservations made during three field visits (3-5 days each)in Kapurdi and Jalipa Lignite Mining areas of the districtBarmer in the year 2008 The field observations were spreadover three major seasons viz winter (January) summer(May) and monsoon (September) These observations havebeen supported by the indispensable works of Rahmani(1997) Sivaperuman et al (2005) and Kumar et al (2006)

Introduction
Barmer district lies in western part of Rajasthan It is a partof Thar Desert (or Great Indian Thar Desert) of Rajasthan Itis surrounded by the district Jaisalmer in the north Jalorein the south Pali and Jodhpur in the east and Pakistan inthe west (c 270 km)
Some information on avifauna of the district Barmer iscontributed by Rahmani (1997) Sivaperuman et al (2005)and Kumar et al (2006) Rahmani (1997) stated that theThar has high avian diversity of nearly 250 species He alsoprovided detailed notes for 213 species which he identifiedduring his surveys (nearly half being non-desert taxa)including 35 species of birds from Barmer district LaterSivaperuman et al (2005) while dealing with avian diversityof 271 species and district-wise distribution of birds in 13districts of the Thar Desert of Rajasthan provided a list of91 bird species for Barmer district Subsequently Kumar etal (2006) in their Geo-spatial Atlas for the Wetland Birdsof Thar Desert Rajasthan made a mention of 53 species of
wetland birds from the district Barmer
Similarly last year when we got an opportunity to undertakethe General Faunistic Surveys (one of the primary objectives
of the Zoological Survey of India) for an Impact Assessment
of the proposed Lignite Mining on Fauna in Kapurdi andJalipa Blocks and surrounding zone of 10 km radius ofBarmer district (Rajasthan) we also maintained a separate
record of the birds we observed and recorded in the studyarea of c 850 sq km This resulted in to a total of 60 speciesof birds
As there is no exclusive bird list for the district Barmer itwas considered worthwhile to compile all these foregoingscattered bird lists and prepare a comprehensive birdchecklist for the district Barmer The present checklist ofbirds deals with a total of 153 species belonging to 103genera and 46 families (Table)
Study area
The district Barmer covers a total area of 28387 km2 and islocated at an altitude of 226 meters between the coordinates240-270 N and 700-730 E The variation in temperature invarious seasons is quite high Usually the temperature variesfrom 270 C to 430C during summer (may soar to 460C to480C) and from 100C to 260C during winter (sometimes itdrops to 50C) Primarily the district is a desert where averagerainfall in a year is 277mm However extreme rainfall of 549

The nomenclature and systematic sequence of birds as givenby Manakadan amp Pittie (2001) has been followed Theidentification of birds and information on their residentialstatus basic food habits etc is based on Ali amp Ripley (1968-78) Grimmett et al (1998) Kazmierczak (2000) and Kumaret al (2005) The conservation status presented here is asassigned by IUCN (2007) BNHS (2002) and Jhunjhunwalaet al (2001)
Analysis and Results
A total of 153 species of birds belonging to 103 genera and46 families have so far been recorded from the districtBarmer It constitutes about 42 of the avian diversity of364 species of birds (Idris et al 2009) known from TharDesert of Rajasthan Interestingly of these 153 species ofbirds 59 are water birds (Table)
The family-wise analysis indicates that family Muscicapidae-the most dominant family- leads the scene with 14 speciesfollowed by Anatidae- Ducks and Geese (12 species)Accipitridae- Vulture amp Eagles and Scolopacidae- Sandpipersamp Stints (10 each) Ardeidae- Heron amp Egrets (8) Alaudidae-Larks (7) Motacil l idae- Wagtails amp Pipits (6) andCharadriidae- Plovers amp Lapwings and Sturnidae- Starlingsamp Mynas (5 each) and so on (Table)
The following 15 species are listed under various threatcategories (3 CR 1 EN 4 VU amp 7 NT) by IUCN 2007 (Table)

Of the 153 species nine are listed under Schedule I of theIndian Wildlife (Protection) Act 1972 (amended up to 2003)126 under Schedule IV and one under Schedule V while15 species do not appear in any of these Schedules- NLA(Not Listed in the Act) (Bombay Natural History Society2002) whereas information on the remaining two species isnot available and is indicated with the sign of question mark() (Table)
In all 21 species are categorized as the Biome RestrictedSpecies (BRS) - a biome may be defined as a major regionalecological community characterised by distinctive animaland plant species Of these one species is from the Sino-Himalayan Subtropical Forest- Biome (08) one from Indian
Peninsula Tropical Moist Forest- Biome (10) 17 from Indo-Malayan Tropical Dry Zone- Biome (11) one from Indo-Gangetic Plains- Biome (12) and one from Saharo-SindianDesert- Biome (13) (Jhunjhunwala et al 2001) (Table)
The analysis of various categories and subcategories ofresidential status of these 153 species is summarised below(Table)

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

E-mail spbhatnagar2002yahoocoinIntroduction
National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

mm rain between August 16 and August 25 2006 left manydead and huge losses As many as 20 new lakes formedand 6 covered an area of over 10 km2
The district has two main seasonal rivers namely Luni Riverand Sukri River The former originates from the Nag hills ofAjmer flows through Jodhpur and Jalore districts flowingthrough the SE portion of Barmer and then it enters theadjoining southerly state of Gujarat and finally falls intoKachchh region (c 320 km long) Until the place of Balotarathe water of the Luni (Salty) is sweet but after that thewater becomes salty (Luni) The Sukri River flows from closeto Mount Abu of the Aravalli Range flows through the districtsof Sirohi Jalore and Barmer in Rajasthan and finally mergesinto the Luni River in district Barmer
The vegetation of the district is sparse and dry deciduoustype consisting of a small range of slow-growing thornytrees shrubs and grasses that has adapted itself to theharsh conditions The most commonly found tree speciesare the ubiquitous khejri (Prosopis cineraria) and varioustypes of acacia which are extremely drought resistantdue to their deep root system Another tree that dots thedistrict is the rohira (Tecoma undulata) The various shrubsoccurring being the phog (Calligonum polygonoides) khair(Capparis decidua) ak (Calotropis procera) and thor(Euphorbia caduca) While important grasses include thesewan (Lasiurus sindicus) dhaman (Cenchhrus ciliaris)boor (Cenchrus jwarancusa) and bharut (Cenchruscatharticus)
An analysis of the digital interpretation in terms of threedifferent canopy density class by the Forest Survey of IndiaDehra Dun reveals that of its total geographical area of 28387km2 the district Barmer has only 060 forest cover whichincludes 12 km2 of moderately dense forest (40-100) 157km2 of open forest and 00 of very dense forest (Anonymous2005)
Methodology
The present contribution is largely based on the recent fieldobservations made during three field visits (3-5 days each)in Kapurdi and Jalipa Lignite Mining areas of the districtBarmer in the year 2008 The field observations were spreadover three major seasons viz winter (January) summer(May) and monsoon (September) These observations havebeen supported by the indispensable works of Rahmani(1997) Sivaperuman et al (2005) and Kumar et al (2006)

Introduction
Barmer district lies in western part of Rajasthan It is a partof Thar Desert (or Great Indian Thar Desert) of Rajasthan Itis surrounded by the district Jaisalmer in the north Jalorein the south Pali and Jodhpur in the east and Pakistan inthe west (c 270 km)
Some information on avifauna of the district Barmer iscontributed by Rahmani (1997) Sivaperuman et al (2005)and Kumar et al (2006) Rahmani (1997) stated that theThar has high avian diversity of nearly 250 species He alsoprovided detailed notes for 213 species which he identifiedduring his surveys (nearly half being non-desert taxa)including 35 species of birds from Barmer district LaterSivaperuman et al (2005) while dealing with avian diversityof 271 species and district-wise distribution of birds in 13districts of the Thar Desert of Rajasthan provided a list of91 bird species for Barmer district Subsequently Kumar etal (2006) in their Geo-spatial Atlas for the Wetland Birdsof Thar Desert Rajasthan made a mention of 53 species of
wetland birds from the district Barmer
Similarly last year when we got an opportunity to undertakethe General Faunistic Surveys (one of the primary objectives
of the Zoological Survey of India) for an Impact Assessment
of the proposed Lignite Mining on Fauna in Kapurdi andJalipa Blocks and surrounding zone of 10 km radius ofBarmer district (Rajasthan) we also maintained a separate
record of the birds we observed and recorded in the studyarea of c 850 sq km This resulted in to a total of 60 speciesof birds
As there is no exclusive bird list for the district Barmer itwas considered worthwhile to compile all these foregoingscattered bird lists and prepare a comprehensive birdchecklist for the district Barmer The present checklist ofbirds deals with a total of 153 species belonging to 103genera and 46 families (Table)
Study area
The district Barmer covers a total area of 28387 km2 and islocated at an altitude of 226 meters between the coordinates240-270 N and 700-730 E The variation in temperature invarious seasons is quite high Usually the temperature variesfrom 270 C to 430C during summer (may soar to 460C to480C) and from 100C to 260C during winter (sometimes itdrops to 50C) Primarily the district is a desert where averagerainfall in a year is 277mm However extreme rainfall of 549

The nomenclature and systematic sequence of birds as givenby Manakadan amp Pittie (2001) has been followed Theidentification of birds and information on their residentialstatus basic food habits etc is based on Ali amp Ripley (1968-78) Grimmett et al (1998) Kazmierczak (2000) and Kumaret al (2005) The conservation status presented here is asassigned by IUCN (2007) BNHS (2002) and Jhunjhunwalaet al (2001)
Analysis and Results
A total of 153 species of birds belonging to 103 genera and46 families have so far been recorded from the districtBarmer It constitutes about 42 of the avian diversity of364 species of birds (Idris et al 2009) known from TharDesert of Rajasthan Interestingly of these 153 species ofbirds 59 are water birds (Table)
The family-wise analysis indicates that family Muscicapidae-the most dominant family- leads the scene with 14 speciesfollowed by Anatidae- Ducks and Geese (12 species)Accipitridae- Vulture amp Eagles and Scolopacidae- Sandpipersamp Stints (10 each) Ardeidae- Heron amp Egrets (8) Alaudidae-Larks (7) Motacil l idae- Wagtails amp Pipits (6) andCharadriidae- Plovers amp Lapwings and Sturnidae- Starlingsamp Mynas (5 each) and so on (Table)
The following 15 species are listed under various threatcategories (3 CR 1 EN 4 VU amp 7 NT) by IUCN 2007 (Table)
1 Indian White-backed Vulture Gyps bengalensis C R 2 Long-billed Vulture Gyps indicus C R 3 Red-headed Vulture Sarcogyps calvus C R 4 Egyptian Vulture Neophron percnopterus E N 5 Marbled Teal Marmaronetta angustirostris V U 6 Lesser Kestrel Falco naumanni V U 7 Sarus Crane Grus antigone V U 8 Pied Tit Parus nuchalis V U 9 Darter Anhinga melanogaster N T10 Painted Stork Mycteria leucocephala N T11 Oriental White Ibis Threskiornis melanocephalus N T12 Lesser Flamingo Phoenicopterus minor N T13 Cinereous Vulture Aegypius monachus N T14 Laggar Falco jugger N T15 Black-tailed Godwit Limosa limosa N T
Of the 153 species nine are listed under Schedule I of theIndian Wildlife (Protection) Act 1972 (amended up to 2003)126 under Schedule IV and one under Schedule V while15 species do not appear in any of these Schedules- NLA(Not Listed in the Act) (Bombay Natural History Society2002) whereas information on the remaining two species isnot available and is indicated with the sign of question mark() (Table)
In all 21 species are categorized as the Biome RestrictedSpecies (BRS) - a biome may be defined as a major regionalecological community characterised by distinctive animaland plant species Of these one species is from the Sino-Himalayan Subtropical Forest- Biome (08) one from Indian
Peninsula Tropical Moist Forest- Biome (10) 17 from Indo-Malayan Tropical Dry Zone- Biome (11) one from Indo-Gangetic Plains- Biome (12) and one from Saharo-SindianDesert- Biome (13) (Jhunjhunwala et al 2001) (Table)
The analysis of various categories and subcategories ofresidential status of these 153 species is summarised below(Table)

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

E-mail spbhatnagar2002yahoocoinIntroduction
National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

The nomenclature and systematic sequence of birds as givenby Manakadan amp Pittie (2001) has been followed Theidentification of birds and information on their residentialstatus basic food habits etc is based on Ali amp Ripley (1968-78) Grimmett et al (1998) Kazmierczak (2000) and Kumaret al (2005) The conservation status presented here is asassigned by IUCN (2007) BNHS (2002) and Jhunjhunwalaet al (2001)
Analysis and Results
A total of 153 species of birds belonging to 103 genera and46 families have so far been recorded from the districtBarmer It constitutes about 42 of the avian diversity of364 species of birds (Idris et al 2009) known from TharDesert of Rajasthan Interestingly of these 153 species ofbirds 59 are water birds (Table)
The family-wise analysis indicates that family Muscicapidae-the most dominant family- leads the scene with 14 speciesfollowed by Anatidae- Ducks and Geese (12 species)Accipitridae- Vulture amp Eagles and Scolopacidae- Sandpipersamp Stints (10 each) Ardeidae- Heron amp Egrets (8) Alaudidae-Larks (7) Motacil l idae- Wagtails amp Pipits (6) andCharadriidae- Plovers amp Lapwings and Sturnidae- Starlingsamp Mynas (5 each) and so on (Table)
The following 15 species are listed under various threatcategories (3 CR 1 EN 4 VU amp 7 NT) by IUCN 2007 (Table)
1 Indian White-backed Vulture Gyps bengalensis C R 2 Long-billed Vulture Gyps indicus C R 3 Red-headed Vulture Sarcogyps calvus C R 4 Egyptian Vulture Neophron percnopterus E N 5 Marbled Teal Marmaronetta angustirostris V U 6 Lesser Kestrel Falco naumanni V U 7 Sarus Crane Grus antigone V U 8 Pied Tit Parus nuchalis V U 9 Darter Anhinga melanogaster N T10 Painted Stork Mycteria leucocephala N T11 Oriental White Ibis Threskiornis melanocephalus N T12 Lesser Flamingo Phoenicopterus minor N T13 Cinereous Vulture Aegypius monachus N T14 Laggar Falco jugger N T15 Black-tailed Godwit Limosa limosa N T
Of the 153 species nine are listed under Schedule I of theIndian Wildlife (Protection) Act 1972 (amended up to 2003)126 under Schedule IV and one under Schedule V while15 species do not appear in any of these Schedules- NLA(Not Listed in the Act) (Bombay Natural History Society2002) whereas information on the remaining two species isnot available and is indicated with the sign of question mark() (Table)
In all 21 species are categorized as the Biome RestrictedSpecies (BRS) - a biome may be defined as a major regionalecological community characterised by distinctive animaland plant species Of these one species is from the Sino-Himalayan Subtropical Forest- Biome (08) one from Indian
Peninsula Tropical Moist Forest- Biome (10) 17 from Indo-Malayan Tropical Dry Zone- Biome (11) one from Indo-Gangetic Plains- Biome (12) and one from Saharo-SindianDesert- Biome (13) (Jhunjhunwala et al 2001) (Table)
The analysis of various categories and subcategories ofresidential status of these 153 species is summarised below(Table)

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

E-mail spbhatnagar2002yahoocoinIntroduction
National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

FIRST SIGHTING OF COMMON SHELDUCK (Tadornatadorna) AND GREATER SCAUP (Aythya marila) ATDEEPOR BEEL ONLY RAMSAR SITE OF ASSAMDIPANKAR LAHKAR PG Dept of Wildlife and ConservationBiology North Orissa University Baripada Orissa- 757003d i p a n k a r l a h k a r g m a i l c o m LAKHAN TERON Natu ra l is t Aaranyak andBISWAJIT BARUAH PG Dept of Wildlife and ConservationBiology North Orissa University Baripada Orissa- 757003
Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters

As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

and elsewhere in the country (Ali and Ripley 1983Parasharya and Naik 1990) The storks were also reportednesting on large Prosopis juliflora trees at Delhi Zoo (Desaiet al 1978 Urfi 1993) however nesting on Prosopis bushesstanding in water is uncommon
According to Shri Dharsinh Raydhan Prajapati of Palasvavillage (Pers Comm October 2005) the water of Munjasartank was used up for irrigation by the farmers The rapiddecline in water level might have forced the storks to desertthe colony before schedule However no mortality wasobserved at the nesting sites Many big trees such asBanyan Neem Peepal were present at the tank peripheryhowever the storks used only Prosopis for nesting

We visited Munjasar Tank (230 26 44 N 700
56 51 E) about 2-3 km south to Palasva village
in Rapar Taluka of Kachchh district on 25th January2006 The tank had almost dried up as the stored
water was being lifted for irrigation by installing diesel pumpsThe soil of tank was moist at the western end indicatingthat it had dried recently
The tank harbors a colony of Painted Stork which was firstnoticed by a group of bird watchers in 2005 A detailedaccount of the colony was given by Varu and Pomal (2006)They recorded about 150 active nests of Painted Stork and300 nests of Eurasian Spoonbill When we visited the colonyin January 2006 a total of 33 adult Painted Storks (Mycterialeucocephala) were seen soaring in the sky They hadnested on the Prosopis juliflora grown on tank bed and their9 juveniles (old enough to fly) were standing on ground as atestimony to their successful breeding Prosopis juliflora isthe dominating plant species within this tank The nestingactivities had ceased when we visited the site All thejuveniles had fledged from the nests and those present wereold enough to fly
The colony was primarily composed of Painted Storks nests
on Prosopis juliflora bushes In all 156 large nest platformswere counted on more than 40 bushes The number of nestson each bush varied between 2 and 6 most frequently 3This nesting site was spread over an area of 1 sq km Storkshad used thorny sticks of Prosopis juliflora as nestingmaterial All nests looked white due to deposition of excretaof the birds A few nests had fallen to the ground Severalsmall nest platforms of Eurasian Spoonbill (Platalealeucorodia) were also seen interspersed with the largernesting platforms of storks
Average height of Prosopis juliflora varied from 2 to 3 msuggesting that the nests might have been very close tothe water surface when the nesting activity commenced inSeptember Prosopis bushes standing in water undoubtedlyprovided a safe substratum for nesting and safety againstground predators
Painted Storks are known to nest on large trees such asBanyan (Ficus bengalensis) Peepal (Ficus religiosa) Neem(Azadirachta indica) Babul (Acacia nilotica) etc in Gujarat

National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

National Chambal Wildlife Sanctuary Rajasthan Kota hasa Wildlife Protected Area of 28000 (km2) This Wetland helpsin maintaining freshwater flows within Chambal RiverSystems (Kalisind Parbati Banas and Kuno (Fig1)
The Indian Skimmer (Rynchops albicollis Swainson 1838Local Name Panchira (Hindi) is one of the ThreatenedSpecies (Class Aves Order Charadriformes FamilyRynchopidae) found in the National Chambal WildlifeSanctuary Rajasthan Kota where it is patchily distributed
Zusi (1996) Islam and Rahmani (2002) and Kumar (2006)declared this bird as a Vulnerable Species due to its rapiddeclining population as a result of widespread degradationand disturbance of rivers and lakes
No detailed systematic studies have been carried out sofar on the eco-behaviour of this threatened Indian skimmer
in the past in India and is also poorly known and is by nomeans exhaustive To fill up the lacuna in the knowledge onthe eco-behaviour of the Indian Skimmer in the NationalChambal Wildlife Sanctuary Rajasthan Kota this study
was carried out The paucity ofinformation on the ecology andbiology of the Indian Skimmerprompted an extensive fieldstudy of this Wetland Bird
The present study is the firstattempt to gathersimultaneously base l ineinformation on the basic ecologyof Indian Skimmer that are foundin the Chambal River basinecosystem
The present study was carriedout for three consecutive yearsfrom 2005 to 2008 with thefollowing objectives
1 To obtain precise data on thepresent distribution of the IndianSkimmer
2 To examine Wetland habitatspresently holding IndianSkimmer
3To determine whether in suchWetland habitats the IndianSkimmer are transient orresident
4 To determine exact breedingareas to study the constraints
on such Wetland habitats and to prepare management plansfor such Wetland habitats for their complete protection
5 To study the ecology of the Indian Skimmer with specialreference to the breeding success of the species in Wetlandhabitats of its distribution and investigate the parametersrequired for breeding success
6 To study the dispersal and seasonal movements of theIndian Skimmer
7 To prepare on the basis of the data obtained amanagement plan for the conservation of the Indian skimmer

The Standardised Common and Scientific Names andBinomial Nomenclature of the Indian Subcontinent byManakadan and Pitte (2001) and Vernacular names of theBirds of the Indian Subcontinent (Buceros (1998) 1 1-53)have been followed in the investigation
Methodology
Field observations were made using Binoculars (7x35 and20x50) and a Terrestrial Telescope (D = 80 mm F 900mm Startracker Refractor) in natural condition The naturalpopulation was assessed by directly counting the IndianSkimmer in all transects by foot in the Chambal Riveraquatic area habitat The Indian Skimmer density wasestimated by Line Transect Method (Emlen 1971) Directobservations of the Indian Skimmer in nature (RepeatedStandard Field Observations described by Hartley (1948
and 1953) were followed
Behavioural activities were studied by Focal AnimalSampling Method (Altman 1974) Regular observationsof behaviour and periodic nest searches were carried out forbreeding seasonality Calls were recorded with theapproximate distance of the display rattle using a SonyWalkman (Professional and UnidirectionalMicrophone) The Indian Skimmers were observedindividually during each visit and the duration of each activitywas measured with a Stopwatch Food and Feeding habitswere studied by direct standard f ield observationsFrequency of feeding and resting from different strata andlocations during different hours and months was recorded
Observations and Results
The observations and results of the findings are mentionedhere
1 The Indian Skimmer (Rynchops albicollis Swainson1838) is a species of waterbird one of the three membersof the skimmer family Rynchopidae It is found in the NationalChambal Wildlife Sanctuary Rajasthan Wetland habitatwhere it is patchily distributed The highest count totalsduring these periods were 155
2 It is 40-43 cm long with a wingspan of 108 cm It is blackabove and white below with a white collar and forehead Thewings are long and pointed with a white trailing edge Theshort forked tail is white with blackish central feathers Thelong thick bill is orange with a yellowish tip and has a lowermandible which is longer than the upper mandible The legsand webbed feet are distinctively red It has an aerodynamicbody and long supple wings that cut through the air withelegance
3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

Beds)] (Figs 3 4 on page 29) we found a single deadindividual of a moderate-sized bird (larger than a crow andsmaller than an eagle and darker in colour) seemed to bea raptor (by its rufous brown plumage and aerodynamicsilhouette) in one of its corner The bird was partiallyentrapped in sludge cakes As the sludge tank wasabsolutely dried out due to incessant atmospheric heatowing to progressive summer we approached closer to thesludge bed near the dead bird On a closer examination ofa carcass the dead individual of a bird was found to be aPariah Kite (Milvus migrans govinda) As we searched theentire sludge bed with an awful astonishment we found intotal five dead individuals of Pariah Kite in a single sludgebed dispersed in different corners Later as we surveyed allthe sludge tanks (four in number with six sludge beds eachtotaling 24) of ASTP in total 42 carcasses of Pariah Kitewere reported Similarly a death of about 500 individuals ofdifferent species of migratory waterfowls has been reportedin oil-sand ponds of Alberta which was filled with oily toxicsludge (KokuRyu 2008) In Egypt large numbers of deadstorks have also been reported at poorly managedwastewater treatment plants (domestic and industrial) dueto drowning entrapment in sludge sinking in aninappropriate sewage ponds or die from drinkingcontaminated water (BioMap 2007) In recent past massmortality of Sea gulls by anthropogenic activities has alsobeen reported in Lakhota Lake Jamnagar Gujarat bySoni (2007)
The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)
On 7th March 2009 as a part of our industrial excursion wevisited 106 MLD Ahmedabad Sewage Treatment Plant(ASTP) managed by Ahmedabad Municipal Corporation(AMC) Gujarat The plant is functional from 1st July 2007and presently being operated and maintained by DNPInfrastructures Ahmedabad The detailed specifications ofASTP are mentioned herewith (Tables 1 2)

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

3 The Indian Skimmer forage for food by flying low over thewater with the bill open and the lower mandible skimmingthrough the water They feed mainly on medium-sized fishand fingerlings but also take crustaceans and water insectlarvae They feed at dusk and through the night Being aspecialised feeder they require clean clear waters Thisspecies is highly susceptible to surface water pollution Theysit in groups on sand-bars
4 It is most common on freshwater during the breedingSeason Breeding colonies are found on sandy or on sandyspits in Chambal River Basin They breed in colonies ofupto 45 pairs The nest is a simple scrape on the groundan unlined depression in the sand in a dry Chambal Riverbed The eggs are laid between March and May The eggsare buff and grayish white with brown blotches and streaksIncubation apparently is by females When first hatchedbills of downy chick are of normal shape and horn-colouredThere are three to five eggs in a clutch
5 Non-breeding adults are duller and browner than breedingbirds Juveniles are grey brown above with pale fringes tothe feathers on the back and wings The head has morewhite than in adult waterbirds and the bill is orange-brownwith dark tip
6 It has a high nasal screaming call but is often silentSometimes a deep yapping call in the breeding season
7 Due to increased human usage of Chambal River BasinWetland many colonies have been plundered andsubstrates mined cultivated and settled and many feedingareas have been over-exploited polluted and drained
8 Currently there are no conservation activities targetingthis Vulnerable Species Urgent attention is neededInvolvement of public community participation and publicawareness in conservation actions are needed

The sewage sludge is the residual semi-solid material leftfrom industrial or wastewater treatment processes Itconsists of two basic forms raw primary sludge (faecal
material) and secondary sludge (a mixture of anaerobicmicrobes that help remove contaminants from wastewaterbefore it is discharged into rivers or seas) The sludge istransformed into biosolids using a number of complextreatments such as digestion thickening dewatering dryingand lime stabilization Treated biosolids can be producedin cake granular lumps pellet or liquid form and are spreadover the land before being incorporated into the soil or injecteddirectly into the soil by specialist contractors Such typesof digested sewage sludge can be used as a soil conditionerbut may contain toxic materials Therefore some of theEuropean countries eg Switzerland Sweden and Austriahave already banned the use of sewage sludge as a fertilizer(Wikipedia 2009)

The Black kite is commonly referred to as thePariah Kite (Milvus migrans govinda Sykes 1832)
due to its scavenging habits (Ripley 1982) belongsto Order Falconiformes and Family Accipitridae It is one ofthe resident birds of the Indian subcontinent widespreadthroughout the Indian Union in all biotopes and zonesexcluding Trans-Himalaya and Islands distinguished by itsforked tail (particularly in overhead flight) than all other kitesfound in India (Ali and Ripley 1995 1996) The bird isbrownish in colour chiefly dwells in rustic and urbanlocalities found either single or gregarious sexes alike butmorphologically female averages 2 to 6 per cent larger in allraces and 10 to 17 per cent heavier than male (Naoroji2007) while male proportionately 86 per cent of female insize (Ferguson-Lees and Christie 2001) Both sexes sharein the domestic duties From the ancestral time this speciesis treated as one of the only commonest dark raptor and aconfirmed commensal of man generally observed in nearbyhuman habitations scavenging in and around nomadicsettlements outlying hamlets villages towns and evenpopulated cities (Kazmierczak 2000) The feeding habit ofthe species is exhibited by an exclusive scoop-up of scrapsfrom a traffic-congested thoroughfare offal and garbage andalmost anything else that can be effortlessly procuredavoiding tangles of overhead telephone and electric wireswith masterful ease (Ali 2002)

The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards

CROWS HECKLING A MARSH HARRIER NIRMALA
CHATHOTH Volunteer Nature Club Surat
Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

dark green and tail black The flock of birds was not disturbedand continues to feed in the shallow water of the Beel for nearly20 minutes They were observed foraging close to the RuddyShelduck (Tadorna ferruginea) No calls were herd
As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

Sunday mornings if we (volunteers of Nature Club Surat) arein the city our destinations are Gavier Lake Eco farm Tapiriver bank or Dumas for birding On 29th March 2009 I chose tovisit the Gavier Lake I was not expecting much as the winterwas almost gone and I expected the lake to be empty But Iwas in for a surprise as always in nature The lake was shallowbecause the flow to the lake through the canal was minimalon account of diversion of water for irrigation of summer cropsHence about 30 to 40 of the lake was dry and this hadattracted so many waders to the lake The lake was full ofbirds and my checklist went up to 60 species for the day Icalled up other members of our club and we all settled for agood birding The Wagtails and Marsh Harriers had not yet
commenced their return journey or perhaps may be on theirlast leg Two Marsh Harriers were hovering over the lake makingthe birds to fly and settle This continued for some time Thenone of the Harriers caught a bird and settled on a drier part ofthe lake to savor its prey I was about 50 meters away from theHarrier and my binoculars were focused on the bird A HouseCrow arrived and perched on a tree near me and started callingin a peculiar manner I was annoyed by its repeated calls and Ishooed it away But instead of flying away it went to another treenearby and continued to call in the same manner Soon after Iignored the crow and kept a watch on the feeding activity of theHarrier To my surprise a few House Crows started landingnear the Harrier one after the other and I counted 32 Housecrows They gathered around the Harrier and pestered it to giveup its meal At that point the Harrier spread it wings and tail toform a semicircular barrier between its prey and the crows Thecrows did not give up one by one they started pulling the wingand tail feathers of the Harrier but seldom did they venture infront of the Harriers beak The Harrier did not bother much
about the heckling crowd completed its meal and went in searchof another The disappointed crows had to content themselveswith the meager leftovers such as feathers and bones of theprey Soon the crows left the spot nonchalantly Nature has givenme so many wonderful experiences and this was yet anothernoteworthy experience

Deepor Beel as proposed WLS (26o0326 - 26o0926N and90o36 39 - 90o46 25 E) is a fresh water natural wetlandoccupying an area of around 414 Km2 in the Kamrup district ofAssam It is the lone Ramsar Site of the state and the second ofits kind in Northeast India after Loktok in Manipur The Beel hasa perennial water-holding area of about 101 Km2 which extendsup to 401Km2 during floods It was proposed as a Bird
Sanctuary with 41Km2 core area About 122 species ofseasonal migratory and residential birds visit the Beel everyyear (P Saikia and PC Bhattacharjee Unpublished)Considering the importance of the wetland Deepor Beel hasbeen included in Asian Directory (DA Scott (ed) 1989) and hasbeen also declared as a Ramsar Site (no1207) in 2002
On Sunday December 6 2006 I visited the wetland for birdwatching On approaching the water body I observed a flock offive white ducks having distinct chestnut band on the breastdark head with pink bill The ducks were identified as CommonShelduck (Grimmett et al1999 Ali and Ripely1983) after havingobserved at close quarters
The birds had dark green head with scapular stripe which canbe clearly observed from a distance The neck plumage was

As I moved to the Southern side of the wetland on boat I sawanother flock of ducks looking similar to the Tufted Duck (Aythyafuligula) but differed from the Tufted Duck in not having thecharacteristic occipital tuft As I focused my binocular I couldidentify an individual as the Greater Scaup The frontal view ofthe Greater Scaup looks very similar to the Tufted Duck butthrough the binocular its deep green head and grey throat wasdistinctly observed The mantel portion was dark white and tailwas black The flock was observed for approximately 10 minutesfrom approximately 60ft and 8 adults were recorded
Common Shelduck is uncommon winter visitor and occursporadically and irregularly in small parties and generally foundin open lake and large rivers (Ali and Ripely 1983) The GreaterScaup is also winter visitor (Grimmett et al1999)
The Common Shelduck and Greater Scaup are not included inthe checklist of the birds of Deepor Beel earlier (Barman et al1995) Thus this is the first report of these two rare species ofducks at Deepor Beel

Pers Comm) which could be due to close proximity of theplant by Vasna Barrage Pirana Dumping Yard and SabarmatiRiver frequently hovered by Pariah Kites in search of foodand nesting materials As the recorded mortality of PariahKite is gaining a peak day by day the projected mortalityrate (~ 480 to 500 birds per year) of the species could bealarming for the urbanites ecologists as well asconservationists As per the authorities of ASTP sludgetanks are filled with fluid sludge every week which get driedwithin two weeks and transformed into lumpy and fluffycakes of dry or stabilized sludge in fourth week Later theremaining water is discharged into River Sabarmati Thusfluid sludge (a treated wastewater) is converted into drysludge cakes within a month which are sold as manure ata rate of Rs 500 per quintal to the stakeholders which is tobe used by farmers in agricultural farming practices later
The probable reasons behind the communal death of PariahKites in ASTP could be due to the inconsistent compositionof domestic wastewater and industrial effluents infusion ofchemical residues along with heavy metals during thetreatment processes and unchecked toxicity levels (almostcritical than normal) of dry sludge cakes prior to its stake-holding It is proven that the treatment process does notremove 100 of the pathogens which profuse their growthsignificantly afresh after spreading which could have beenone of the major cause for the Kites mortality As a large
amount of sludge produces acids when get oxidized thepractice of adding sludge into agricultural farms to neutralizesoil acidity should discouraged in order to prevent themortality granivorous birds (Goio 2008)
In future to prevent such a huge mortality of Pariah Kitesas well as other resident birds in and around ASTP followingmitigating measures should be taken at immediate concerns(1) Checking the physico-chemical characteristics of inflowof domestic and industrial effluents before loading to thePrimary Treatment Unit (2) Viable processing of wastewaterduring 1st and 2nd Stage Biological Treatments (3) Monitoringof normal (permissible) toxicity levels of fluid sludge (4)Preparation of less toxic sludge beds with dry cakes (5)Covering each sludge bed with green mate to prevent falling
of birds therein (6) Use of reflector taps around each bedunit tank or plant to deviate the bird-path and (7) Incinerationof substantial amount of sludge to eliminate suchbiohazards
Till date as no such attempt has been made to report amass mortality of birds by sewage or sludge in India anation-wide systematic survey should be carried out to studythe effect of sewage and sludge on the communal death ofbirds in and around sewage treatment plants and sludgedisposal sites (landfills) of towns cities and metros In futuresuch types of case-studies may confer the causes concernsand preventive measures of mass mortality of birds due tospanning industrialization and urbanization to protect themfrom such man-made hazards
