World Wetlands Day 2012:

BLB educates future leaders for wetlands conservation

World Wetlands Day (WWD) has been commemorated on 2 February every year since 1997. This year,

BirdLife Botswana (BLB) celebrated the day with 23 primary school children and teachers from

Diphetogo Primary School and Mogoditshane Primary School, in Gaborone Game Reserve (GGR). BLB

took this opportunity to raise awareness and understanding of school children about wetlands and

water birds, through bird watching.

The visit started with a briefing on the origin of WWD and the objectives of the event. BLB birding

specialists took children to the waterholes to watch various aquatic birds. The biodiversity at the

waterhole amazed children who had actually never visited GGR before. With their eyes shining,

they were so excited to see and listen to the calls of approximately 50 bird species including

Egyptian Goose Sehudi, Hamerkop Mmamasiolanoka, Hadeda Ibis Tshababarwa and African Sacred

Ibis Kokolohutwe.

WWD originated from the signing of the Convention on

Wetlands, called the Ramsar Convention, on 2 February

1972, in the Iranian city of Ramsar. The Ramsar Con-

vention (The Convention on Wetlands of International

Importance, especially as Waterfowl Habitat) is one of

the United Nations Multilateral Environmental Agree-

ments/Conventions for the conservation and sustain-

able utilization of wetlands. Currently there are 161

contracting parties, one of which is Botswana.

After the tour, children enjoyed their picnic at the

recreational area. GGR is a most convenient destina-

tion which provides abundant wildlife (especially water

and bush birds), and plant resources for environmental

education.

Wetlands, visit www.ramsar.org

A breeding account of a pair of Lilac-breasted Rollers

in a Francistown garden, August - December 2011

A nest-log, formed from a natural log, had been used for many years in different places where I have resided. Pre-vious occupants have been African Hoopoes Upupa epops and Cape Glossy Starlings Lamprotornis nitens, both spe-cies having bred successfully in Jwaneng, Harare and Francistown. This particular log is one metre long and on average 35cm in diameter. A 5cm entrance hole was cut using a small saw and according to a known Lilac-

breasted Roller's natural nest-hole diameter.

The log was fixed to a stout acacia tree branch in the front garden of my house at a height of 1.6m above ground

level. The hole faced west and leaned forward at about 10o from the vertical – the hole pointing to the ground.

In early August 2011 a swarm of bees took over in the log but were smoked out before any combs could be made. However, the swarm persisted and had to be smoked out for a second time. The bees then massed in the tree sup-porting the log and hung like a large rugby ball for several days before dispersing. I pushed some dry vegetation

into the nest-log to create a soft pad for any potential nesting bird.

Later that same day, they moved into a square-section metal cross-beam on a power pole supporting the same wires on which the initial (assumed) mating took place. There was much of their well-known raucous calling as

Cape Glossy Starlings had also been looking at this potential nest-site.

*This was the first time I had seen a metal, horizontal pipe being used by rollers. Since then, however, in his lat-est book Nests and Eggs of Southern African Birds, Warwick Tarboton states that these pipes are also favoured by

rollers. I was quite concerned how the birds would cope due to the heat conducted from the sun by the steel pipe.

On 19 October the rollers were back in the garden amid much calling and fighting off Crested Barbets Trachy-

phonus vaillantii.

On 23 October the pair copulated again, this time in the nest-log tree. During the rest of the afternoon, the male

would bring various insects, mainly large grass-hoppers, to the log for the female.

On the morning of 24 October the female appeared at the entrance hole. It is not known whether or not she over-

nighted inside the nest-log. During much of that day, the pair was in and out of the log calling loudly.

On 26 October municipal workers were burning off dry grasses and scrub by the road-side just outside the bound-

ary wall of my house. The fires attracted Fork-tailed Drongos Dicrurus adsimilis as well as the rollers.

On 29 October the male brought a large locust or grass-hopper to the female and mounted her on the branch at

the nest site.

By Mike Soroczynski

On 28 August two Lilac-breasted Rollers Coracias caudata arrived at the log with the male inspecting the interior by clinging to the edge of the entrance hole and peering up and down inside. Being so dark inside, one wonders what the bird

could have been looking for or what it had seen!

The female perched on a specially-erected branch attached near the entrance hole and waited for the male to complete his inspection. The two birds then flew off but returned later in the day to chase off two African Hoopoes which also

seemed interested in the log.

There was much to-ing and fro-ing by the rollers until, on 14 October, the birds were seen mating on a nearby power-line. It was here that the mounting bird showed a pronounced hook on the tip of its beak whereas the other bird had no hook –

see photograph for comparison.

Lilac-breasted Rollers breeding continued….

On 30 October a small illuminating lamp was lowered into the nest chamber and with the aid of a small mirror, four white eggs were seen. The frequency of the egg-laying is not known but there were no eggs on 24 October.

Both birds took turns to incubate from then on.

On 4 November there were still the four eggs. A large sand lizard was brought to the nest. On inspecting the log

at 09h00 on 13 November one egg was seen to have hatched.

Points for discussion

i. The choice of nest site seemed to have been decided on by the initial copulation site – firstly on the power line – although that was abandoned. The second act was in the tree where the breeding eventually

occurred.

ii. The larger prey items, lizards and snakes, were brought only when the weather was hot. Is the appearance of such reptiles dictated by such temperatures as the cooler temperatures only saw beetles,

termites and grass-hopper- sized insects being caught.

iii. If this is the case, would the absence of larger prey account for the demise of the other three chicks?

iv. There was a great deal of time taken to decide on the nest site. This was not this case with previous observations at the Jwaneng nest-site. There seems to have been much greater competition for nesting

sites here in Francistown where a greater number of hole-nesting species exists than at Jwaneng.

v. At least 20 days incubation for the eggs.

vi. At least 28 days taken for the surviving chick to fledge. Would this have been a shorter period had the

climate been warmer?

A blind, naked (apart from a scant covering of hair-like down) chick was seen beside the three other eggs and the broken shell of its own egg. By 13h30 the same day, there was a clucking sound from within the nest and when the bird left, a second egg was seen to have hatched. The air

temperature was 40oC.

By 19 November all four eggs were seen to have hatched

and four gaping beaks were visible.

On 20 November a 30cm green-coloured snake was brought to the nest and dropped into the nest chamber. The snake

appeared to be dead.

No more inspections of the inside of the log were made to reduce further disturbance. Beetles, termites, lizards and

several snakes were brought in as food items.

From hereon in, the weather turned much cooler and wet-ter and the resultant prey was reduced to beetles, grass-

hoppers and termite alates.

By 3 December a chick started to appear at the entrance hole to receive food from the adults. Apparently, only one

chick had survived.

On 11 December the chick made its maiden exit from the nest. It either flew to the upper branches of the nest-tree

or clambered up – probably a bit of both.

By the morning of 14 December the chick was still being fed at the nest-log but by late afternoon there was no sign of

the chick or the adults.

Life in the Days of Dabchicks in Mokolodi

One of the delights of the rainy season is watching the bird activity on the small dam on our

plot. Every year, according to the rain pattern, there is a different scenario and species. Some of

you will remember our resident crocodile who thankfully moved on to the dam next door after two

years ‗chez nous‘. This year, with poor and late rains giving forth to an abundance of reeds and wa-

ter plants, has been one of the best.

Even though our dam ‗hosts‘ a wide variety of

birdlife, one species is always faithful. Within

two days of the first good rains, we can be as-

sured of the presence of the Dabchick, or Little

Grebe.

It spends the first 24 hours furiously swimming

back and forth inspecting its new surroundings,

obviously ticking off its suitability checklist. We

have been turned down in the past by quite a

few, but always one will turn up who calls our

dam ‗home‘. Then comes the question of a mate!

This year we had a few spats where a couple of males arrived fighting for the female and the terri-

tory. Our small dam ain‘t big enough for the three of them, so with their time clocks ticking away,

the happy couple quickly settled down to domestic bliss. This entailed the building of their impres-

sive nest hidden amongst the water foliage. They build it high with sodden leaves and matter dragged

from the bottom of the dam. It looks like a soggy mound.

We were lucky to locate their nest quite easily this year. Once the eggs are laid, they cover them

with the soggy foliage if not sitting on the nest and get very territorial seeing off anything else that

moves close to it. One of their characteristic behaviours is to scoot across the water, skimming the

surface and giving off an extremely piercing trilling sound.

A few weeks ago our hearts stopped beat-

ing as there was a huge commotion in the

area of the nest and with the aid of our

binos, we were horrified to see a monitor

lizard trying to get into or on to the

nest. The dabchicks, amazingly fero-

cious for their size , somehow managed

to beat the monitor lizard off. However

we don‘t think it left empty handed - or

empty bellied! For a few days afterwards

the poor dabchicks were extremely skit-

tish and even frightened off a couple of

moorhens with whom they had been hap-

pily sharing their territory.

It all went very quiet for a week and then Mark in-

vited the Kalahari Hash House Harriers to run

through our plot as part of a weekly run which he

was setting..........

Although they kept as quiet as a bunch of runners

can, the next day we saw the dabchicks relocating

to another spot closer to the centre of the dam

which actually gave us a better view of proceedings.

After some furious ‗renesting‘ activity and about

five days, we were eventually rewarded by the sight

of two tiny chicks. Once off the nest they go swim-

ming on the back of the parent‘s back and when the

dabchick dives for food, they are under the back

feathers. They are now swimming behind the par-

ents who are teaching them how to dive for the deli-

cacies that lie under the water etc.

No further sighting of the monitor lizard, but we know he is around. Terrapins also abound in our dam. Whether these chicks will survive we can only hope. If they do hopefully they will return to our dam next year.......

Ornithologists generally discover new species by collecting them in the wild. But early in the 20th century, Museum ornithologst James P.Chapin found one on a hat. In 1913, Chapin, while serving as an assistant on an expedition to the Belgian Congo, came upon a tribesman of the Ituri Forest wearing a headdress with a distinctive feather. To the young naturalist it suggested a pheasant or peacock, a strange possibil-ity since these birds were native to Asia. Curious, he took it. Fast forward to 1936. Chapin was visiting the Congo Museum in Tervuren, Belgium and, by pure chance, found atop a cabinet a pair of taxidermied birds. A label indicated they were familiar Indian or Blue Peacocks, but he suspected otherwise - feathers on these birds matched the one he collected 23 years earlier. Later that year, in a professional journal he described Afropavo congensis or the Congo Peacock, a unique species whose closest relatives are the Asian peacocks. Eager to pursue his discovery in its habitat, Chapin returned to Africa in 1937 and in a forest in what is now the Democratic Re-public of the Congo, he observed the birds on the ground and in flight and heard their night-time call. Over the years, ornithologists have hypothesized that Afropavo is more closely related to African guinea fowls or Old World partridges. However, genetic studies suggest Afropavo is a sister taxon to the Pavo species, the bird commonly known as the peacock, and that Chapin's hunch 100 years ago was right.

Ed’s note, courtesy Wikipedia:

Congo Peacock (Afropavo congensis), a species of

peafowl, is the only member of the genus Afropavo.

It inhabits and is endemic to lowland rainforests of

the Congo River Basin in central DRC. The diet con-

sists mainly of fruits and invertebrates. The male

has a similar display to other peacocks, fanning its

tail in this case, while other peacocks fan their up-

per tail coverts. The male Congo Peafowl is monoga-

mous, though information from the wild is needed.

Very little is known about this species. It has charac-

teristics of both the peafowl and the guineafowl,

which may indicate that the Congo Peafowl is a link

between the two families.

Due to ongoing habitat loss, small population size

and hunting in some areas, the Congo Peafowl is

evaluated as Vulnerable on the IUCN Red List of

Threatened Species.

This has to be the weirdest thing that ever floated past me in the river...A highly p‘d off chicken snake wound tightly around a struggling falcon's neck. They were stuck together in a deadly embrace, each wanting to kill the other first. My guess is that the falcon dived down and snatched the tasty chicken snake from a nearby patch of open ground and the snake somehow got its tail wound around the hapless bird‘s neck and began strangling it in midair, causing them to fall into the nearby Comal river. Unbelievably, they both survived and are alive and well, considering the odd circumstances. I think if a few more minutes had elapsed, the snake might have won the contest as its tail was actually tied in a tight knot around the bird's neck and getting tighter by the second. I pulled them from the water & quickly untied the snake. This is a prime example of those odd ball stories you occasionally tell which is usually acknowl-edged with "Yeah, right !!!" But as you can see … I have the pictures to prove it. Amazingly neither of the exhausted pair tried to bite or scratch me. The chicken snake, though not venomous, didn‘t want to stop biting the fal-con's leg. It only let go after I had untied its body from the bird's neck. I stayed with the bird until its plumage was al-

most dry and it was ready to fly away.

A chicken snake tightly wound around a falcon's neck has got to be one of the weirdest things I have ever seen and pulled out of the water ...

You never know what’s going to fall out of the sky . . .

Kids For Birds

compiled by Doreen McColaugh

Photos Eugenie Skelton Dear Kids,

Are some birds lazy?

Just as some people avoid some of their responsibili-ties by saying that they involve too much hard work for them to do, so it seems that some birds follow the same thinking. These birds, called brood para-sites, have cleverly or lazily figured out how to avoid their hardest job (other than finding food to eat and to avoid being eaten by something else) which is to

produce and raise their own offspring/chicks.

A parasite is defined as something or someone that depends on another for its support or existence with-out giving anything in return. So a brood parasite is a bird that depends on another bird (of a different species) to incubate its eggs and raise the chicks once they hatch. Around the world there are five families of birds that are parasitic brooders. The cuckoos, honeyguides and the whydahs and widow-finches are from the three families of these birds that occur in southern Africa, including Botswana, that parasitize other birds. These birds do not make nests for themselves. They select certain species of birds to be their ‗hosts‘ or ‗foster mothers/parents‘. Some of the species of parasitic breeders will only choose one other species as their hosts, while others choose a wider range. The notorious Diderick‘s Cuckoo is known to parasitize up to 24 different spe-

cies of birds.

How do they get away with it? How do they get other birds (their hosts) to accept their eggs, incu-bate them and then raise their chicks? Now ‗host‘ means one that receives or entertains guests so-cially, but for these birds it seems that ‗host‘ means one that can be taken advantage of. These brood parasites select certain birds as their hosts, but they do so without the hosts‘ permission. The brood parasites are very sneaky and patiently wait and watch their selected hosts. When the hosts have made their nest and the female has started to lay their eggs in it, the cheating cuckoo, honeyguide, whydah or widowfinch patiently waits out of sight until the female leaves the nest for a short time be-tween laying her eggs or finding some food, and then the brood parasite quickly moves to the nest and

lays her egg.

She might destroy one of the host‘s eggs so that it‘s not noticed that there is an extra egg in the nest. Or she might lay an egg that matches the host‘s egg so well with the same size, same shape, same colour and same patterns that the host female will not no-tice the difference. Clever, huh? Brood parasites‘ eggs take less time to incubate than other eggs and so they hatch a day or so before the host‘s eggs. This gives the first hatched chick an advantage. Be-ing older, bigger and stronger it can demand more food from the host parents who most often feed them before their own chicks because the older one can dominate the younger chicks. The parasitic brooder‘s chick also may destroy the host‘s eggs by pushing them out of the nest before they hatch or if the eggs are left in the nest and they hatch, those

chicks may be killed by the parasitic brooder‘s chick.

You may at some time have seen, and wondered about, a small bird feeding a chick that is much lar-ger than the bird feeding it that supposedly is its mother or father. If so, what you saw was a brood parasitic chick being fed by its foster/host parents

who end up working almost like slaves to raise it.

The big question is: How does a cuckoo chick, for example, incubated and raised by a weaver – and never having seen its real mother or father – know how to be a cuckoo? How does it know to parasitize, as well as know which species to select as hosts when it grows up? How does it know its own species

calls and everything else that makes it a cuckoo?

In the next issue we will look more closely at the parasitic brooder species that occur in Botswana and what species they target as hosts. Be on the look-out for small birds feeding chicks that are much bigger and of different colours and markings than the smaller birds are. You might be observing parasitic

brooding in action!
