SSSSpring is in the air and hopefully the coldweather of winter will be behind us soon.

Yet it will be hard for us to forget thefreezing temperatures and snowfalls at theend of 2010. Records were broken all aroundIreland and according to Met Éireann, it wasthe coldest December on record. The lowestDecember air temperature ever measured inthe country, -17.5oC, was recorded atStraide, Co. Mayo, on 25th December. Snowfell in almost all parts of the country, evenon Sherkin Island, which rarely sees snow.Why not download NASA’s image of Irelandand see if you can find where you live?

Itattracts many birdsbut in recent weeks hehas got more than hebargained for!Everyday, usually inthe morning, abeautiful malepheasant arrives topick at the seed on the ground. The little birds don’tseem to mind the pheasant, which Dad has namedGeorge, and they all happily feed together.

Fact FileFact FileFact FileFact FileColour: Female is brown, male has reddish-brown plumage with black bars on feathers. Hishead is a shiny green, black and violet colourand has red around the eyes. Also has whitecollar around the neck, but this may not bepresent on the least common race of the tworaces that are present in Ireland.Length: 70-90 cmDiet: Roots, berries, seeds, leaves and insects.Habitat: Woodlands, marshes, hilly areas,rough land and tillage farmland.

Scientific Name: Phasianus colchicusIrish Name: Piasún

Pheasant

TTTT he male pheasant is a very striking bird. He has beautiful reddish-brown plumage, a colourful head and neck and a long tail. The

female is very different as she has much plainer colouring and ashorter tail. Her paler brown plumage helps to camouflage her whenshe is on her nest, which she usually builds out of leaves and grass onthe ground. Sometimes however, she will roost on trees where she canbe safe from foxes. When out and about, pheasants spend the day onthe ground searching for roots, berries, seeds, leaves and insects.Pheasants are not native to Ireland but are a species which originallycame from Asia and were introduced into Ireland in the 16th century.There is no other bird in Ireland that is similar to the pheasant.Pheasants are gamebirds, which means they are hunted for food andfor sport.Top: The colourful male pheasant.

Above: The less colourful female.

What does it sound like?What does it sound like?What does it sound like?What does it sound like?A pheasant has a hoarse alarm call when it isfrightened, which sound like ke-tuk, ke-tuk. Itdecreases in strength when the bird flies off.

George might like the daffodils aswell as the bird see!

The Intelligence of OctopiThe Intelligence of OctopiThe Intelligence of OctopiThe Intelligence of OctopiOOOOctopi have the largest

brains of all the animalswithout backbones.They also have eyes as complexas those found in humans andare masters of camouflage,changing their colour and skintexture almost instantaneously,to blend in with theirbackground.Experiments conducted on anoctopus named Frida at MunichZoo have shown that octopi canbe taught complex tasks, suchas unscrewing a jam jar to get atthe food inside, or even to worktheir way around mazes, the waya laboratory rat would.Observations on the matingbehaviour of octopi on a reefoff Indonesia in recent yearsshow that octopi engage insophisticated courtship ritualsincluding flirting, passionatehand holding and even keepingrivals away at arm’s length.The male octopus carefullyselects a mate and then guardsher den against all potentialrivals until mating takes place,after which he lives for only ashort time until the eggs hatch,and then he dies.Ireland has its own nativespecies called the “CurledOctopus”, which are normallyvery shy and difficult to find inthe wild. But you can see themon display in many of theexcellent public aquaria aroundthe country at Galway, Bray,Fenit or Dingle.

A Mind of its OwnA Mind of its OwnA Mind of its OwnA Mind of its OwnResearch conducted at the Hebrew University of Jerusalem shows thateach arm of an octopus has, quite literally, “a mind of its own”.Each arm has its own intelligence, powered by some 50 million nervebundles or “neurons” that allow it to perform complex movements setoff by a simple command from the octopus's brain.A severed octopus’s arm was even made to move realistically on its ownby tickling and stimulating the skin.

Insect EyesInsect EyesInsect EyesInsect EyesHow do insects see the world?How do insects see the world?How do insects see the world?How do insects see the world?

By Thomas Daguerre

HHHHave you ever looked at the bulging bug eyes of a fly, a wasp or a beetle andwondered how exactly they see the world? Whether, like people, they can see all

the amazing colours and shapes we see everyday?It is hard to answer these questions precisely as we cannot take the place of a bumble bee as it visitsflowers or an ant as it collects seeds. However, scientists have discovered a great deal about howthese small creatures see the world. It is as varied and incredible as the number of different types ofinsects that live in your garden.

ColourColourColourColourInsects see colours verydifferently to people. This isbecause most of them viewthe world in a differentcolour spectrum, calledultra violet, which makescertain colours stand out. Bees use ultraviolet to find flowers that have lots ofpollen in them and other insects, likebutterflies, use ultra violet to find a mate.

Big eyes & small eyesBig eyes & small eyesBig eyes & small eyesBig eyes & small eyesINSECT EYESINSECT EYESINSECT EYESINSECT EYESNormal sight in insects depends on two special organs - Compound eyesCompound eyesCompound eyesCompound eyesand simple eyessimple eyessimple eyessimple eyes.

The compound eyeThe compound eyeThe compound eyeThe compound eyeThe compound eyes of insects are themain organ of sight. The outer surfaceof each eye is formed by a number ofsmall lenses called facets. facets. facets. facets. They are in away similar to your pupil letting lightinto the eye. The number of facetsvaries from 1 in some insects to20,000 in others. If there are only afew facets they are circular in shape, but

in most insects there are many facets all packed closely together - in thiscase they are hexagonal like honeycomb. Behind each facet there is atube-like structure known as the ommatidiumommatidiumommatidiumommatidium. Each one of theseommatidium, or tubes, casts a small segment of the image captured bythe facet down into the eye. What this means is that the insect’s eyeproduces a kind of “pixellated” image, much like a digital photo or yourcomputer screen. When all the small pixels are combined an image iscreated.

The simple eyeThe simple eyeThe simple eyeThe simple eyeThe simple eye is also known as the ocelliocelliocelliocelli. Simpleeyes usually number 3 and are placed on the topof the insect’s head. As their name suggests, theyare very simple and can only detect light or dark.

A great variety of different vision exists in theinsect world. Next time you see a colourful beetle or a scuttling spider tryand think how they see you!

Hoh Rainforest, Olympic Peninsula, Washington, USA, is a temperate rainforest.

Tropical RainforestsTropical RainforestsTropical RainforestsTropical RainforestsTropical rainforests are foundnear the equator. They occur inplaces where the weather is warmand humid, enabling thevegetation to grow thick and fast.In these forests rain falls nearlyevery day throughout the year,with over 200cm of rain fallingeach year. However, in somerainforests they have much.Thelargest rainforest in the world isthe Amazon Rainforest in SouthAmerica, which has about 280cmof rain each year.

Temperate RainforestsTemperate RainforestsTemperate RainforestsTemperate RainforestsTemperate rainforests are foundin temperate countries of theworld. They occur in eastern Northand South America, northeasternAsia, southern Australia andwestern and central Europe.Thedifference between summer andwinter temperatures in thesecountries is not too extreme - thesummers are not very hot nor arethe winters very cold. Yearlyrainfall in a temperate rainforestranges from 75 cm to 150 cm.

Where did your interest intrees come from?From childhood one of thefirst books I rememberreading was “Robin ofSherwood and his MerryMen”. This sparked myimagination and led to roleplaying with my brothersand sisters in a place calledCastlefreke Wood in WestCork. I think it was there I

gained a love for theoutdoors and trees inparticular.What training did you doto get where you aretoday?I went to University inWales where I completed adegree in Forestry. I thenworked as a contractor fora number of years in theforestry sector mainly

doing tree measurementsand timber volumeestimations. I joinedCoillte under a graduaterecruitment programmeand spent some timeworking in Wicklow,Wexford and am now basedhere in Castleisland inCounty Kerry.What type of work doyou do?My work is quite varied andmainly involves planning thetimber type and quantity tobe harvested from theforests to supply thesawmills. I make sure thatfelled areas are replantedto sustain timber supplyinto the future and that allour forests are kept cleanand visually attractive. Ialso manage forest

recreation areas, maintainforest walking trails, picnicbenches, viewing points etc.Another important part ofmy job is protecting andenhancing biodiversity areasassociated with the forests.Is there any rare orunusual wildlife in theforests you manage?Yes, the Hen Harrier, oneof Ireland’s and Europe’srarest birds of prey, nestsin young forests in theupland areas nearCastleisland. I protect thisspecies by minimising anydisturbances like harvestingclose to nest sites and bymaintaining a succession ofyoung forests.What is the best thingabout your job?The variety and being ableto work both indoors andoutdoors. One moment Icould be on the officecomputer and the next Icould be fighting a forestfire.What is the worst thingabout your job?I hate to see any dumping inthe forests. UnfortunatelyI regularly come acrosspiles of domestic waste, cartyres, sofas, mattresses,washing machines and burntout cars. I work with litterwardens and the Gardai totry and eliminate thisdumping.What would you do if youweren’t doing what youdo?Boatbuilding……….. with woodof course!.

A 1,000 Common Dolphins off Cork CoastA 1,000 Common Dolphins off Cork CoastA 1,000 Common Dolphins off Cork CoastA 1,000 Common Dolphins off Cork CoastThe Irish Whale and Dolphin Group (IWDG) receiveda report from Mícheál Cottrell (from Baltimore, Co.Cork). He was hauling nets on a commercial fishingboat in mid-February, off the Old Head of Kinsale inCo. Cork, and his skipper shouted to him that a hugepod (herd) of Common Dolphins was "working"(feeding) in the area. There were at least 1,000dolphins in the pod and they could be seen on the fishing boat’sradar. They appeared to cover an area of about 0.75 x 1.5 nauticalmiles. According to the IWDG, Common Dolphins have a behaviour(practice) of feeding in teams. It appears that they have learnedthat it is far easier to find food if they co-operate with eachother rather than striking off on their own. Cooperation is good!

Celebrating International Year of the ForestCelebrating International Year of the ForestCelebrating International Year of the ForestCelebrating International Year of the ForestNational Tree Week, which is organised by The Tree Council ofIreland, has just celebrated its week-long celebration of trees in ourlives and environment. This year the theme of the week was ‘The Yearof the Forest - Celebrating Forests for People’ in keeping with theUnited Nations’ ‘International Year of the Forest’. The Tree Council ofIreland tell us that even though Ireland has made great advances inthe past 100 years, it is still the least wooded country in Europe. Only11% of our land is covered in trees, compared to an average of 40% inthe rest of Europe. Ireland has agreed to plant moretrees so that our forests will cover 17% of thecountry by 2035. To learn more about woodlands,check out the ‘Balrath Project’ on www.treecouncil.ie/schools.html. The Tree Council of Ireland, along withMeath County Council, are developing Balrathwoodland in Co. Meath as an ‘outdoor classroom’.

• They provide us with materials tobuild, furnish and heat our homes.

• They help to produce the oxygenwe breathe.

• They are one of our mostimportant wildlife habitats andprovide homes for vast numbersof plant and animal species.

• They prevent air pollution byabsorbing carbon dioxide from the atmosphere.

• They stabilise the soil, helping to prevent landslides, andabsorb excess ground water, helping to prevent flooding.

• Not only do they do all these things, but they also provide uswith beautiful amenities for us to enjoy.

Coillte, Ireland's leading forestry company, welcomes over eighteenmillion visitors to its forests each year.

OrienteeringOrienteeringOrienteeringOrienteeringWhat is it?What is it?What is it?What is it?

TTTT he Irish Orienteering Association describes orienteering insimple terms as finding your way from one point to another,

using only a map, a compass and your brain. Orienteering is usuallydone in the woods, hills or parks, with the participants on foot.At a typical organised Orienteering event, several courses of varyingdifficulty are laid out in the woods by the event organisers. Each course consists of a series ofcheckpoints (or “controls”) marked by a brightly coloured, distinctive Orienteering flag. Participantsare given a map with the locations of the checkpoints circled. The starting place, the sequence in whichyou visit the controls, and the finish location are also shown. Then, using the map and a compass, it's upto the participant to find his or her way from one control point to another in the order specified.The Irish Orienteering Association welcome beginners. If you would like to try it, check out theirwebsite www.orienteering.ie for information.

WWWWith the help of local orienteering clubs, Coilltehas set up a number of permanent

orienteering sites at various forests around thecountry. Coillte’s sites cater for orienteers in thebeginners, intermediate and experienced categoriesand course maps for each category are available fordownload. These courses are an ideal way ofintroducing children and adults to orienteering. Goat your own pace and spend as much time as you likefiguring out the map and navigating to the controls.Permanent orienteering courses can be used for amore adventurous family stroll, or for training togain confidence away from the pressure of moreorganised orienteering competitions.The forest habitat provides a wonderful opportunityto learn more about nature. To facilitate this,Coillte have developed educational resource materialfor use at some of their sites: Hellfire Club (Co.

Dublin), Carrickgollogan(Co. Dublin), Farran

Forest Park (Co. Cork)and Lough Key ForestPark (Co. Roscommon).

The pages for these sites include the followinginformation:• Primary and Secondary School Course maps• a work book, based on the primary science

curriculum,• a more advanced workbook for

second level, junior cycle students,and,

• Teachers’ Answer Sheets• Check them out at www.coillteoutdoors.ie

Orienteering is considered a competitive sportby some but for many casual walkers it is arecreational activity. People come out alone,with friends, or with family, admiring theview and taking time to appreciate nature. Itcan be considered a walk with some mentalchallenge added.
