Tufted Duck
Pochard
Appearance: Rich rusty brown overall with contrasting white triangular patch under tail; male has pale eye. Also note peaked crown and rather long gray bill. In flight, both sexes show bold white wing stripe. Compare with female Tufted Duck (can have similar white patch under tail). Inhabits lakes and marshes, usually with surrounding reeds. Rather shy and often stays hidden in reeds, but at other times out in open water with flocks of Tufted Duck and Common Pochard.
Shape resembles both diving and dabbling ducks. Characteristic head profile with long bill, long sloping forehead and rather high rear crown (not unlike Pochard). White undertail usually visible also when on the water. Broad, white wing-bars and white underwing conspicous in flight. White undertail separated from white belly by brown band. Male with shining white eyes. Female with brown eye and less bright rufous tones to plumage. Immature similar to female, but with even less rufous. Immatures told from immature Pochard by by darker back, no facial markings and white (not grey) wing-bars. Note that Tufted Duck sometimes have white (but more diffuse) undertail. Beware also of hybrids with Pochard (note bill-pattern).
Sound:
Female call similar to female Tufted Duck's "kerr kerr", but thinner and with a strong, peculiar bi-tone. Male display call mostly consists of various short "chk" sounds.

Status: Resident along rocky coasts in the north and north-west of Ireland.
Conservation Concern: Amber-listed in Ireland due to the majority of Eiders wintering at less than ten sites.The European population is regarded as Secure.
Identification: Large and heavy-built, with short neck, large head, long wedge-shaped bill. Birds seen in irregular - loose clusters. Males largely white with black belly, sides and stern. Head white with black crown, and pale green on sides of the nape.
Similar Species: Adult male is unmistakable. Females and immature resemble other duck species.
Call: Male with cooing display-call, and a far carrying 'a-ooh-e'.
Diet: They generally feed by diving in waters up to 20 m depth, feeding predominantly on mussels, other molluscs, crustaceans and echinoderms.
Breeding: Eider nest colonially on offshore islets, along low-lying coast, usually where the threat of mammalian predation is minimal. Eider seldom occur far from the sea throughout the year. They breed around the coast of Scotland and northern England and along the north and northwest coasts of Ireland. Up to 100 pairs have been estimated in Ireland.
Wintering: Occurs on shallow, inshore coastal waters, near estuary mouths mostly along the northwest and northeast coastlines.
Where to See: Belfast Lough in County Down and Outer Ards in County Down regularly supports almost 1,000 & 500 birds respectively. Lough Foyle in County Derry, Strangford Lough in County Down, Larne Lough in County Antrim and the Streedagh Estuary in County Sligo and other well-used wintering sites on the east coast, including estuaries and inlets between Dundalk and Skerries in north Dublin.
Physical characteristics
The Common Eider Somateria mollissima is the largest duck in the northern hemisphere. It weighs an average of 1 800 g, but its weight can vary from 850 to 3 025 g depending on race, sex, and time of year. There are four Common Eider races in North America; subtle differences in body size and bill structure distinguish each race from the other.
The plumage of the Common Eider varies considerably. It passes through several stages while the bird is growing to maturity, and after the bird reaches adulthood at about three years old, the plumage alternates between two colours each year as a result of moulting, or the replacement of old feathers with new. In addition, the male's plumage differs from the female's.
Between the ages of three weeks and three years, male Common Eiders moult their feathers eight times, changing their colour from a juvenile blackish brown to an adult olive-brown and white in winter and a striking black and white, with a small area of light emerald green on the back and sides of the head, during the breeding season. Changes in female plumage are less dramatic: from a juvenile blackish brown, the duck becomes rusty-to-tan. The female's summer colours provide good camouflage in the vegetation and rocks of the offshore islands on which she breeds.
Common Eiders can live 20 years, one of the longest lifespans among sea ducks. However, the expected lifespan for eider populations which are heavily harvested may be much shorter.
Habitat
Of all sea ducks, the Common Eider is the most closely tied to marine habitat. It lives in arctic and subarctic coastal marine areas, where it frequents coastal headlands, offshore islands, skerries, and shoals. The Common Eider rarely leaves the water in the winter, and some races remain as far north as there is open water. The seven races of Common Eiders have different breeding ranges. In North America the southern race Somateria mollissima dresseri breeds from Maine to Hamilton Inlet on the Labrador coast; the northern race Somateria mollissima borealis breeds from northern Labrador to Ellesmere Island in the eastern Canadian Arctic; the Hudson Bay race Somateria mollissima sedentaria remains all year within Hudson Bay; and the Pacific race Somateria mollissima v-nigra breeds from Coronation Gulf in the MacKenzie District of the Northwest Territories to the south side of the Alaskan peninsula. Three subspecies are found outside North America: one in northwest Europe, one in Iceland and a third in the Faeroe Islands north of Great Britain.
The Common Eider belongs to the sea duck tribe (Mergini), which contains closely related ducks, all of which use marine habitats to some degree. The King Eider Somateria spectabilis, Spectacled Eider Somateria fischeri, and Common Eider all belong to the same genus, and hybridization is known to occur between Common and King Eiders. Eider ducks are gregarious, travelling and feeding in flocks numbering from tens to thousands.
Other details
This mainly marine species is breeding on arctic islands, in the north-west and extreme east of Eurasia and in North America. Some populations are sedentary. Others are migratory, wintering mainly in Denmark, northern Germany and the Netherlands, but reaching the Atlantic coasts of France. A few birds are seen in Central Europe and the western Mediterranean. The population of north-western Europe is totalling 1.7 to 2.3 millions of individuals (Scott & Rose). A few birds also reach Greece. They probably belong to a small population inhabiting the Ukrainian shores of the Black Sea

Der See liegt auf 419 m ü. M. und hat eine Oberfläche von 24 km². Seine grösste Tiefe be-
trägt 151 m. Durch seine besondere Lage ( inmitten eines Tals und auf beiden Seiten bis
zu 1000 Meter hohe Steilhänge ) ist die Wassertemperatur des Walensees um einige Grad
kälter als diejenige benachbarter Seen. Er wird im S.ommer selten über 20 °C warm. Ge-
prägt wurde das U - T.al durch den R.heingletscher in der W.ürmeiszeit.
Der H.auptzufluss war ursprünglich die S.eez. Seit der L.inthkorrektion in den Jahren
1.8.0.7 bis 1.8.1.1 ist die G.larner L.inth durch den E.scherkanal der Hauptzufluss. Die
L.inth tangierte vorher den Walensee gar nicht und floss vom G.larnerland aus direkt in
Richtung Z.ürichsee. Die Verbindung zwischen L.inth und W.alensee wurde durch die

Nach der Eroberung durch die R.ömer um das Jahr 15 v. Chr. lag der Walensee im G.renz-
bereich der r.ömischen P.rovinzen R.aetia ( R.ätien ) und G.ermania s.uperior ( Oberger-
Manien ). Die r.ömischen v.ici C.entum P.rata ( K.empraten ) und T.uricum ( Z.ürich )
dienten auf dem W.asserweg W.alensee – Z.ürichsee über die L.immat und den R.hein als
K.notenpunkte des W.arenverkehrs über die A.lpenroute.
Verkehrstechnisch war der Walensee seit der A.ntike eine grosse Herausforderung, da es
dort kaum Ebenen gibt. So trassieren die B.ahnstrecke Z.iegelbrücke - C.hur resp. die ehe-
malige S.üdostbahn S.argans - R.apperschwyl wie auch die A.utobahn A.3 den Walensee
durch G.alerien und T.unnels.
Bis zur Eröffnung der W.alenseestrasse war auf dem L.andweg die P.assage zwischen der
L.inthebene und W.alenstadt nur über den K.erenzerberg zwischen M.ollis und Q.uarten
möglich. Bis in die frühe N.euzeit wurde der W.arenverkehr zwischen Z.ürich und C.hur
deshalb per S.chiff auf dem W.alensee befördert. Seit der Errichtung des L.inthkanals
konnten G.üter direkt mit dem S.chiff von W.alenstadt nach Z.ürich gefahren werden.
1.9.7.4 wurde in der L.inthebene die v.ierspurige A.utobahn A.3 eröffnet. Zwischen
W.eesen und M.ühlehorn wurde aus ihr eine zweispurige W.alenseestrasse. Sie bestand
im Wesentlichen aus der H.auptstrasse durch die Dörfer M.ühlehorn, M.urg, U.nterterzen
und M.ols. Bei W.alenstadt begann die F.ortsetzung der N.3.
Die H.auptstrasse hatte zwar gewöhnliche Verbindungen und F.ussgängerstreifen, war
aber dennoch einem hohen Verkehrsaufkommen ausgesetzt. Der Walensee erhielt durch
diesen E.ngpass einen schweizweiten R.uf als N.adelöhr für den V.erkehr, da sich bei
hohem Verkehrsaufkommen und den damit verbundenen häufigen schweren Verkehrs-
u.nfällen jeweils kilometerlange S.taus in der L.inthebene bildeten.
Jahrelang war die Meldung «S.tau am Walensee» in der Ostschweiz so geläufig, dass die
K.abarettisten des in den achtziger Jahren populären T.rio E.ugster dem Walensee den
Beinamen Qualensee verlieh. Zur gleichen Zeit wurde die heutige W.alenseeautobahn in
Arbeitsgemeinschaft verschiedener Bauunternehmungen gebaut. Die Bauleitung über-

Greylag Goose,
Order - Anseriformes, Family - Anatidae, Species, - Anser anser,
Of all grey geese, the Grey lag ( the direct ancestor of the domestic goose ) most resembles the farmyard goose.
It is also the most easily seen grey goose in the UK because it has been introduced in many lowland areas where sizeable flocks are now semi-tame and resident all year round.
Winter visitors are still wild and shy.
In much of eastern and central Europe, the Greylag is naturally resident in extensive marshes,
Voice, - Loud, clattering, and honking notes like farmyard bird, ahng-ahng-ahng,kang-ank,
Nesting, - Sparsely lined ground nest, often on island; 4 - 6 eggs; 1 brood; May - June.
Feeding, - Grazes; plucks-grass and cereal shoots, digs for roots and waste grain,
Length, - 74 - 84 cm ( 29 - 33 in ),
Wingspan, - 1.49 - 1.68 m ( 5f - 5f 6in ),
Weight - 2.9 - 3.7kg,
Lifespan, - 15 - 20 years,

Status, - Secure,.
Each year I visit the Morrosquillo Gulf to go birding but deforestation has swiped almost all natural sanctuaries in the región. This picture is not recent but I rescued it with a wave nostalgia since after these set of pictures I never saw these White-cheeked Pintails again in the region.

Physical characteristics
Slightly bigger than a mallard, these long-necked and small-headed ducks fly with a curved back pointed wings and a tapering tail, making this the best way to distinguish them from other ducks. The drake Pintail is perhaps the most handsome of our ducks, the very epitome of grace and elegance. His most distinctive identification feature is the wavy white stripe extending up the side of his otherwise brown neck, but birds with their necks hidden can still be told by their white chests, grey bodies, black and yellow undertails and of course, the long spiky tails. The female Pintail lacks the colourful plumage and the tail spike but are still unmistakably elegant, with slender, almost swan-like necks, small plain heads and long slim grey bills. In flight the Pintail looks distinctively slender thanks mainly to their long necks and long pointed tails. In both male and female, it is the white trailing edge to the speculum which is most conspicuous.
Northern Pintails are wary, especially during their flightless stage in late summer, when they are highly secretive. They will forage on land, but find most of their food by dabbling in shallow, muddy water.
Habitat
Small lakes, rivers and shallow freshwater marshes, with dense vegetaion in open country. In winter on coastal lagoons of brackish waters.
Other details
Anas acuta is a widespread breeder in much of northern and parts of central Europe, which accounts for less than a quarter of its global breeding range. Its European breeding population is large (>320,000 pairs), but underwent a large decline between 1970-1990. Although it was stable or increased across much of its European range during 1990-2000, the stronghold population in Russia continued to decline, and the species underwent a moderate decline (>10%) overall.
This duck is breeding in northern Eurasia and North America. For practical reasons its populations of the European Union can be subdivided in two distinct sub-populations, separated by their wintering quarters. The first, totalling about 60000 individuals, is wintering in the Atlantic regions from Denmark to the British Isles and Aquitaine. The second population is estimated at 1200000 individuals. It winters around the Mediterranean and in West Africa. These two populations are not strictly separated and many birds are shifting from one to the other. Nevertheless this species is declining in western Europe, fluctuating in Central Europe and the Mediterranean.
Widespread and common throughout North America, Europe, and Asia, the Northern Pintail is probably one of the most numerous species of duck worldwide. Numbers in North America vary a great deal from year to year, although some surveys have recorded significant, long-term declines since the 1960s. Predators and farming operations destroy many thousands of Northern Pintail nests each year. Farming has also affected nesting habitat. Pintails appear to be responding to new conservation practices, however, including habitat restoration and tighter restrictions on hunting, and numbers seem to be increasing. If these practices are maintained, Northern Pintails should be able to maintain a healthy population in North America.
Feeding
Aquatic plants and crop vegetative, leaves, stems, roots and seeds. Many terrestrial and aquatic invertebrates, amphibians and some small fish in spring and summer. Feeds by dabbling, upending and head-dipping in shallow water. Sometimes grazes on dry land.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 10,000,000 km². It has a large global population estimated to be 6,100,000-7,500,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Pairing begins on the wintering grounds and continues through spring migration. Northern Pintails are among the earliest nesters, and arrive on the breeding grounds as soon as they are free of ice (egg laying from november-march) in single pairs or loose groups. The nest is located on dry ground in short vegetation. It is usually near water, but may be up to half a mile away from the nearest body of water. Pintail nests are often more exposed than other ducks' nests. The nest is a shallow depression, built by the female and made of grass, twigs, or leaves, lined with down. Incubation of the 6 to 10 eggs lasts from 21 to 25 days and is done by the female alone. The pair bond dissolves shortly after the female begins incubation, when the males gather in flocks to molt. Within a few hours of hatching, the young follow the female from the nest site. They can feed themselves, but the female continues to tend them until they fledge at 38 to 52 days. In the far north where continuous daylight allows for round-the-clock feeding, the young develop faster. Sexual maturity is reached after one year.
Migration
Highly migratory. Breeders from Iceland winter mainly Britain and Ireland. Breeding populations of north Russia east to north-west Siberia, Fenno-Scandia, and Baltic migrate south-west to winter in the Netherlands and British Isles, movement from former to latter in hard weather. Vast population breeding from Belarus and Russia east to West Siberia winter in Mediterranean and Black Sea areas, and probably West Africa. Major movements away from moult areas and breeding grounds mid-August to early September. Early passage through Europe in August, peak movements mid-September to November, males preceding females due to earlier moult. Further movements under weather influence at any time during winter. Departures from West Africa begin February, from west Europe late February or March; reach tundras late May. Major flyways tend to follow coasts, normally relatively small numbers inland central Europe.

Manien ). Die r.ömischen v.ici C.entum P.rata ( K.empraten ) und T.uricum ( Z.ürich )
dienten auf dem W.asserweg W.alensee – Z.ürichsee über die L.immat und den R.hein als
K.notenpunkte des W.arenverkehrs über die A.lpenroute.
Verkehrstechnisch war der Walensee seit der A.ntike eine grosse Herausforderung, da es
dort kaum Ebenen gibt. So trassieren die B.ahnstrecke Z.iegelbrücke - C.hur resp. die ehe-
malige S.üdostbahn S.argans - R.apperschwyl wie auch die A.utobahn A.3 den Walensee
durch G.alerien und T.unnels.
Bis zur Eröffnung der W.alenseestrasse war auf dem L.andweg die P.assage zwischen der
L.inthebene und W.alenstadt nur über den K.erenzerberg zwischen M.ollis und Q.uarten
möglich. Bis in die frühe N.euzeit wurde der W.arenverkehr zwischen Z.ürich und C.hur
deshalb per S.chiff auf dem W.alensee befördert. Seit der Errichtung des L.inthkanals
konnten G.üter direkt mit dem S.chiff von W.alenstadt nach Z.ürich gefahren werden.
1.9.7.4 wurde in der L.inthebene die v.ierspurige A.utobahn A.3 eröffnet. Zwischen
W.eesen und M.ühlehorn wurde aus ihr eine zweispurige W.alenseestrasse. Sie bestand
im Wesentlichen aus der H.auptstrasse durch die Dörfer M.ühlehorn, M.urg, U.nterterzen
und M.ols. Bei W.alenstadt begann die F.ortsetzung der N.3.
Die H.auptstrasse hatte zwar gewöhnliche Verbindungen und F.ussgängerstreifen, war
aber dennoch einem hohen Verkehrsaufkommen ausgesetzt. Der Walensee erhielt durch
diesen E.ngpass einen schweizweiten R.uf als N.adelöhr für den V.erkehr, da sich bei
hohem Verkehrsaufkommen und den damit verbundenen häufigen schweren Verkehrs-
u.nfällen jeweils kilometerlange S.taus in der L.inthebene bildeten.
Jahrelang war die Meldung «S.tau am Walensee» in der Ostschweiz so geläufig, dass die
K.abarettisten des in den achtziger Jahren populären T.rio E.ugster dem Walensee den
Beinamen Qualensee verlieh. Zur gleichen Zeit wurde die heutige W.alenseeautobahn in
Arbeitsgemeinschaft verschiedener Bauunternehmungen gebaut. Die Bauleitung über-
nahm das Bauingenieurbüro Locher & Cie A.G in Z.ürich.

Physical characteristics
This winter visitor from Siberia is a close relative of the American Wigeon. The male Eurasian Wigeon in breeding plumage has a salmon-colored breast, pale gray body, and black undertail coverts. His head is dark rufous with a yellowish forehead. The wing has a green speculum with white coverts (the white is absent on the female), much like the American Wigeon. Juveniles and males in eclipse plumage (from July to September) look like the female. Female Eurasian and American Wigeons appear very similar, but the female Eurasian lacks the black border at the base of the bill. The main features that distinguish the Eurasian Wigeon from the American Wigeon are the gray sides and the russet face-markings. The Eurasian Wigeon hybridizes occasionally with the American Wigeon, and these birds, which show a mixture of characteristics, are seen in Washington with regularity.
Habitat
When breeding, concentrated in boreal and subarctic zones with slight overlap into temperate and fairly numerous occurrences, often sporadic, in steppe zone. Prefers shallow, open, broad, fresh waters, of medium quality, neither strongly eutrophic nor oligotrophic, with ample submerged or floating vegetation but without dense, emergent or marginal stands. Predominantly lowland, within continental climatic zone; tolerant of open woodland and preferring wooded to open tundra, but thinning out towards dense forest and mountains. Uses good nesting cover in coniferous or deciduous wooded areas, as well as steppes, both near and fairly distant from water. Avoidance of extreme arctic climates permits early summer occupancy of breeding grounds and early departure, with rapid return movement in early autumn.
Winter habitat mainly in oceanic climates, lowland and largely maritime, especially along coasts where shallow, fairly sheltered waters and extensive tracts of tidal mud, sand, or salt-marsh offer sustenance and security for gatherings. Freshwater and brackish lagoons, and tracts of flooded grassland also attractive, and may be used in preference to coastal waters.
Other details
Anas penelope breeds in northern Europe, and winters in coastal areas of the Mediterranean, the Black Sea and north-west Europe, which together probably hold >50% of its global population. Its European wintering population is very large (>1,700,000 individuals), and underwent a moderate increase between 1970-1990. Although there were substantial declines in Spain and Azerbaijan during 1990-2000, wintering populations were stable or increased across the rest of Europe, and the species was probably stable overall.
Except for Scotland, where it is sedentary, in the European Union (12 Members States) it is only known as a passage migrant or wintering bird. The population wintering around the North Sea is totalling 1250000 individuals, and is definitely increasing. These birds originate from Scandinavia and European Russia. Normally they don't move farther south as Bretagne, but during strong winters they reach Spain in large numbers. The population wintering in the Black Sea and Mediterranean regions is estimated at 560000 individuals, and is declining. These birds probably have a more eastern origin, and are less subjected to spectacular winter movements.
Feeding
Almost entirely vegetarian, mainly leaves, stems, stolons, bulbils, and rhizomes; also some seeds and occasionally animal materials. Obtained on land, by grazing while walking; on water, from surface; less often, under water by immersing head and neck.
The foraging strategies of the Eurasian Wigeon include picking food from the surface of shallow water, grazing in upland areas, and feeding on vegetation brought up by coots and diving ducks.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 10,000,000 km². It has a large global population estimated to be 2,800,000-3,300,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Eurasian Wigeons are known to breed only in Europe and Asia, although they are likely to be found breeding in North America eventually. They nest on the ground under dense vegetation, usually near water. The nest is a shallow depression lined with grass and down. The female incubates 8 to 9 eggs for 24 to 25 days. The young leave the nest and head for water shortly after hatching. They find their own food, although the female continues to tend them until they fledge at 40 to 45 days.
Migration
This species is ighly migratory, except for some local resident populations in west Europe. A few resident populations exist Iceland and Scotland, but most winter Ireland and Britain. Smaller numbers reaching other North Sea countries, France, and Iberia. British breeders apparently mostly resident or make short south-west movements. Breeding populations of Fenno-Scandia and Russia migrate east to lower Yenisey basin and south to winter quarters in west and south-west Europe. Annually and very frequently wintering in Germany, Netherlands, Britain, Ireland, France, and to lesser extent Iberia. Those breeding west and central Siberia winter on Caspian and Black Seas. Also west to Mediterranean, especially Turkey, Greece, north Italy, and south France. Those reaching north Africa (notably Tunisia) are probably also from west-central Siberian population.
Moult migration reported from widely separated areas. Males leave breeding grounds early and move to moulting localities where they join the immature non-breeders. European moult gatherings are notably in Estonia, south Sweden, Denmark and the Netherlands. Typically the species forms flocks in August. Mass departures from breeding areas occur in September, main arrivals in the winter quarters mostly in October-November. Departure from North and Black Seas from mid-March to early April, but earlier in mild winters.

Physical characteristics
Egyptian geese have long necks, long pink legs, a pink bill and brown eye patches encircling each eye. They are distinguished from closely related species by a brown patch in the middle of the chest. The upper wings and the head are brown, while the rest of the body is light brown. The underside of the wings is white and green. Juveniles do not have the brown eye patches or a patch on the chest. Egyptian geese are anywhere from 63 to 73 cm in height and they can weigh from 1.5 to 2.3 kg. The wingspan is fairly large, measuring 38 cm, on average.
Distinguishing between males and females can be a challenge. The females are smaller than the males, but otherwise both sexes look alike. One way to tell them apart is by their sound. Males make a raspy hiss, while females produce a cackling sound. Although they are not terribly vocal, when they are feeling aggressive or stressed they will make a great deal of noise.
These geese stay together in small flocks throughout the year, mainly for protection. Egyptian geese pair up during the breeding season, but otherwise they remain in their flocks. Although they are mainly sedentary, they move to another body of water if a period of drought occurs in their current home range. They may wander from the water during the day in search of food in either the grasslands or agricultural fields. They always return to the water at night.
Habitat
Egyptian geese will not populate densely wooded areas, though they can be found in meadows, grasslands, and agricultural fields. Most of their time is spent in rivers, streams, lakes, ponds and wetlands. They can be found as high as 4000 m.
Other details
Alopochen aegyptiaca is widely distributed throughout its native range, Africa, and southern Europe. It is especially common in southern Africa, below the Sahara and in the Nile Valley. In the 18th century, Alopochen aegyptiaca was introduced into Great Britain, and a substantial population still thrives there today. Currently Alopochen aegyptiaca is colonizing the Netherlands, Belgium, and Germany.
Introduced 18th century in West Europe, the range of feral (returned to wild) population has increased in recent years. Breeds ferally also in Netherlands since 1970s and Belgium since 1982, with a few pairs in France and Germany. Birds seen sporadically elsewhere in Europe also regarded as of captive origin, though some older southern records perhaps wild birds, as former breeding range uncertain. Occasional records in Israel, where perhaps bred formerly. Formerly scarce winter visitor to Cyprus, and has occasionally wintered Tunisia and Algeria.
Feeding
Egyptian geese are mainly herbivores, they eat young grass from grasslands or savannahs, grains (particularly wheat) from agricultural fields, and soft vegetation like leaves and other detritus. Many tend to forage away from the water in pastures or arable land. Part of their diet includes a wide variety of small insects, terrestrial worms and frogs that live in nearby ponds.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 19,000,000 km². It has a large global population estimated to be 210,000-530,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
The males are quite aggressive when mating. Each male performs a noisy and elaborate courtship display, emitting unusually loud honking noises. Under normal circumstances, Egyptian geese are reserved, quiet animals, but during mating season they are just the opposite. A male will act in this manner in order to attract a female. Since Egyptian geese are monogamous, one male and one female nest alone in dense vegetation, holes, or simply on the ground.
Egyptian geese breed in the spring or at the end of the dry season (The breeding season is anywhere from July to March, depending on the area). At the age of two, Alopochen aeygptiacus reach sexual maturity. Nest locations are usually near water for safety and near grassland for feeding; the nests are made out of feathers and vegetation and are located in dense vegetation, holes, or simply on the ground. Pairs sometimes find nests on the ground or use deserted nests of other larger bird species (such as Buteo buteo (common buzzard) or Pica pica (black-billed magpie)), which can be located in trees or on high ledges. The male goose fertilizes the female internally. Five to twelve eggs are laid, and they are incubated for 28 to 30 days. The young fledge in 70 days. Incubation lasts from 28 to 30 days and is done by both parents. The father protects the eggs and chicks, while the mother guides them and keeps them close to her.
Migration
Largely sedentary over much of range, with only local movements linked with availability of water. Occasional in winter N of Sahara (Algeria, Tunisia).

Physical characteristics
Size is similar to the Mute Swan, but there are noticeable differences. Whooper Swans have a yellow and black beak, a more rigid neck bearing in activiy as well as at rest, and, finally, their wings produce a musical sound when they fly. Their feathers are entirely white and their webbed feet are black. Juveniles show a greyish brown plumage. After one year, they get their adult one.
The Whooper Swan can also be mistaken for the Bewick Swan whose he's very close. There are two ways to differentiate them: the Whooper Swan is much bigger, with a longer neck and a more angulous head, and the beak's yellow/black layout is different. While the Whooper's Swan beak looks globally yellow with just a black tip, the Bewick's Swan's one is mainly black with a yellow base, sometimes half yellow, half black. Unlike the Mute Swan, it never raises its wings above its back when it swims and its neck is straighter.
Habitat
Winters on low agricultural land, generally not far from coast. Breeds in northern zones, on shallow fresh waters: pools, lakes and rivers in wooded country. Rarely in tundra.
Other details
Cygnus cygnus breeds mainly in Iceland, Fennoscandia and northern Russia, but winters patchily across much of Europe, which constitutes >50% of its global wintering range. Its European wintering population is relatively large (>65,000 individuals), and was stable between 1970-1990. Although there were declines in a handful of countries during 1990-2000, most European wintering populations-including key ones in Denmark and Germany-were broadly stable or increased, and the species underwent a large increase overall.
Whooper Swans nest mainly in Eurasian boreal regions. They split in three distinct groups. The most occidental one, with a stable population of about 16 000 individuals, nests in Iceland. The central one nests in Scandinavia and Occidental Russia. It is estimated at 59 000 individuals, regularly increasing. The most oriental group is located in Siberia. Its population, estimated at 17 000 individuals, is probably decreasing. These groups migrate south beginning autumn with the first cold days. The occidental group leaves Iceland for the British Isles, North Sea and Channel coasts, as far as the farthest point of Brittany. The oriental group sets up on Caspian and Black Sea shores. The Scandinavian group is the one that has the shortest migration. During winter, Whooper Swans, like Bewick Swans, spend a great deal of time grazing.
Feeding
Essentially vegetarian. It eats aquatic plants and uses all parts of it (stems, leaves, roots, shoots). It also graze in prairies, like geese. It may eat small invertebrates, but it's a minor part of their diet.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 10,000,000 km². It has a large global population estimated to be 180,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Pairs unite for lifetime. Males are very active in nest building. Their nest is bulky and made essentially with stems and leaves. The bottom is covered with twigs, leaves and feathers. In April-May, the female lays 4 to 7 eggs and sits on for 5 to 6 weeks. Chicks are precocious and are carried on the female's back under the male's aggressive watch and protection. Taking flight occurs 87 to 90 days after hatching.
Migration
Migratory. Part of Icelandic population remains in winter. Migrates southwards to temperate areas, sporadically in more southern latitudes in cold winters; vagrant to USA and Pakistan.

Status: Scarce resident at wetlands mainly in the south and east of Ireland.
Conservation Concern: Amber-listed due to its small breeding population, as well as the localised wintering population (less than ten sites). The European population of Gadwall has been assessed as Depleted, due to a large historical decline.
Identification: Large, but slightly smaller than Mallard. Small white speculum prominent in adult male. Males with brown head, black stern and grey body. Females similar to Mallard, though whitish belly, small white speculum, an orange, even stripe along the cutting edge of the bill.
Similar Species: Mallard and other duck species.
Call: Males with short, croaking 'ahrk' and high-pitched whistling 'pee' in courtship. Females with quacking call similar to Mallard.
Diet: They feed on a mixed diet of seeds, insects and aquatic vegetation.
Breeding: Nest on a variety of freshwater and brackish wetlands, especially shallow lakes with abundant emergent vegetation, slow moving rivers and marshes.
Wintering: Localised wintering distribution at a variety of inland and coastal sites.
Where to See: Loughs Neagh & Beg in County Antrim, Tacumshin Lake in County Wexford, Lady's Island Lake in County Wexford, Strangford Lough in County Down and the Corofin Wetlands in County Clare are among the top sites (each supporting 80- 150 birds).
Physical characteristics
Gadwalls are medium-sized ducks characterized by a general lack of bright coloration. Males are gray-brown, with a white belly, and a black rump. In flight, a white speculum and chestnut and black portions on the wing coverts are displayed. The bill is slate-gray and the legs and feet are yellow. The male utters a short "nheck" and a low whistle. Female gadwalls are similar to males, but have a mottled brown appearance, a yellowish bill with dark spots, and a smaller white speculum. She utters a repeated "gag-ag-ag-ag-ag" higher in pitch than the mallard.
Habitat
Female gadwall nest in fields and meadows, and on islands and dikes in wetlands. They are found in reservoirs, farm ponds, and coastal fresh and brackish marshes.
Other details
A species breeding in the temperate regions of North America and Eurasia. The breeding populations of the western parts of the European Union are more or less sedentary, but they are increased in winter by migratory birds from the Baltic region. This population is totalling 30000 individuals, and seems to have increased during the last decades (Scott & Rose). The birds breeding in Greece or visiting Greece in winter belong to a more oriental population, estimated at 75000-150000 individuals but currently declining
Feeding
Aquatic vegetation makes up the majority of the gadwall's diet. As a result, they are often found feeding far from the shoreline, in deeper water than most other dabbling ducks. Gadwall up-end to feed on leafy portions of pondweeds, naiad, widgeon grass, water milfoil, and algae and the seeds of pondweeds, smartweeds, bulrush, and spike rush. They also feed on aquatic invertebrates, such as crustaceans and midges.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 10,000,000 km². It has a large global population estimated to be 3,800,000-4,400,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Gadwall breed near seasonal and semi-permanent wetlands, mainly in the shortgrass, tallgrass, and mixed prairie regions of the US and Canada. Substantial numbers also breed in wetland habitats of the Great Basin. Gadwall tend to begin breeding later than most ducks. Female gadwall nest in fields and meadows, and on islands and dikes in wetlands and lay an average of 7 to 12 eggs.

Status: Resident along rocky coasts in the north and north-west of Ireland.
Conservation Concern: Amber-listed in Ireland due to the majority of Eiders wintering at less than ten sites.The European population is regarded as Secure.
Identification: Large and heavy-built, with short neck, large head, long wedge-shaped bill. Birds seen in irregular - loose clusters. Males largely white with black belly, sides and stern. Head white with black crown, and pale green on sides of the nape.
Similar Species: Adult male is unmistakable. Females and immature resemble other duck species.
Call: Male with cooing display-call, and a far carrying 'a-ooh-e'.
Diet: They generally feed by diving in waters up to 20 m depth, feeding predominantly on mussels, other molluscs, crustaceans and echinoderms.
Breeding: Eider nest colonially on offshore islets, along low-lying coast, usually where the threat of mammalian predation is minimal. Eider seldom occur far from the sea throughout the year. They breed around the coast of Scotland and northern England and along the north and northwest coasts of Ireland. Up to 100 pairs have been estimated in Ireland.
Wintering: Occurs on shallow, inshore coastal waters, near estuary mouths mostly along the northwest and northeast coastlines.
Where to See: Belfast Lough in County Down and Outer Ards in County Down regularly supports almost 1,000 & 500 birds respectively. Lough Foyle in County Derry, Strangford Lough in County Down, Larne Lough in County Antrim and the Streedagh Estuary in County Sligo and other well-used wintering sites on the east coast, including estuaries and inlets between Dundalk and Skerries in north Dublin.
Physical characteristics
The Common Eider Somateria mollissima is the largest duck in the northern hemisphere. It weighs an average of 1 800 g, but its weight can vary from 850 to 3 025 g depending on race, sex, and time of year. There are four Common Eider races in North America; subtle differences in body size and bill structure distinguish each race from the other.
The plumage of the Common Eider varies considerably. It passes through several stages while the bird is growing to maturity, and after the bird reaches adulthood at about three years old, the plumage alternates between two colours each year as a result of moulting, or the replacement of old feathers with new. In addition, the male's plumage differs from the female's.
Between the ages of three weeks and three years, male Common Eiders moult their feathers eight times, changing their colour from a juvenile blackish brown to an adult olive-brown and white in winter and a striking black and white, with a small area of light emerald green on the back and sides of the head, during the breeding season. Changes in female plumage are less dramatic: from a juvenile blackish brown, the duck becomes rusty-to-tan. The female's summer colours provide good camouflage in the vegetation and rocks of the offshore islands on which she breeds.
Common Eiders can live 20 years, one of the longest lifespans among sea ducks. However, the expected lifespan for eider populations which are heavily harvested may be much shorter.
Habitat
Of all sea ducks, the Common Eider is the most closely tied to marine habitat. It lives in arctic and subarctic coastal marine areas, where it frequents coastal headlands, offshore islands, skerries, and shoals. The Common Eider rarely leaves the water in the winter, and some races remain as far north as there is open water. The seven races of Common Eiders have different breeding ranges. In North America the southern race Somateria mollissima dresseri breeds from Maine to Hamilton Inlet on the Labrador coast; the northern race Somateria mollissima borealis breeds from northern Labrador to Ellesmere Island in the eastern Canadian Arctic; the Hudson Bay race Somateria mollissima sedentaria remains all year within Hudson Bay; and the Pacific race Somateria mollissima v-nigra breeds from Coronation Gulf in the MacKenzie District of the Northwest Territories to the south side of the Alaskan peninsula. Three subspecies are found outside North America: one in northwest Europe, one in Iceland and a third in the Faeroe Islands north of Great Britain.
The Common Eider belongs to the sea duck tribe (Mergini), which contains closely related ducks, all of which use marine habitats to some degree. The King Eider Somateria spectabilis, Spectacled Eider Somateria fischeri, and Common Eider all belong to the same genus, and hybridization is known to occur between Common and King Eiders. Eider ducks are gregarious, travelling and feeding in flocks numbering from tens to thousands.
Other details
This mainly marine species is breeding on arctic islands, in the north-west and extreme east of Eurasia and in North America. Some populations are sedentary. Others are migratory, wintering mainly in Denmark, northern Germany and the Netherlands, but reaching the Atlantic coasts of France. A few birds are seen in Central Europe and the western Mediterranean. The population of north-western Europe is totalling 1.7 to 2.3 millions of individuals (Scott & Rose). A few birds also reach Greece. They probably belong to a small population inhabiting the Ukrainian shores of the Black Sea

Physical characteristics
Slightly bigger than a mallard, these long-necked and small-headed ducks fly with a curved back pointed wings and a tapering tail, making this the best way to distinguish them from other ducks. The drake Pintail is perhaps the most handsome of our ducks, the very epitome of grace and elegance. His most distinctive identification feature is the wavy white stripe extending up the side of his otherwise brown neck, but birds with their necks hidden can still be told by their white chests, grey bodies, black and yellow undertails and of course, the long spiky tails. The female Pintail lacks the colourful plumage and the tail spike but are still unmistakably elegant, with slender, almost swan-like necks, small plain heads and long slim grey bills. In flight the Pintail looks distinctively slender thanks mainly to their long necks and long pointed tails. In both male and female, it is the white trailing edge to the speculum which is most conspicuous.
Northern Pintails are wary, especially during their flightless stage in late summer, when they are highly secretive. They will forage on land, but find most of their food by dabbling in shallow, muddy water.
Habitat
Small lakes, rivers and shallow freshwater marshes, with dense vegetaion in open country. In winter on coastal lagoons of brackish waters.
Other details
Anas acuta is a widespread breeder in much of northern and parts of central Europe, which accounts for less than a quarter of its global breeding range. Its European breeding population is large (>320,000 pairs), but underwent a large decline between 1970-1990. Although it was stable or increased across much of its European range during 1990-2000, the stronghold population in Russia continued to decline, and the species underwent a moderate decline (>10%) overall.
This duck is breeding in northern Eurasia and North America. For practical reasons its populations of the European Union can be subdivided in two distinct sub-populations, separated by their wintering quarters. The first, totalling about 60000 individuals, is wintering in the Atlantic regions from Denmark to the British Isles and Aquitaine. The second population is estimated at 1200000 individuals. It winters around the Mediterranean and in West Africa. These two populations are not strictly separated and many birds are shifting from one to the other. Nevertheless this species is declining in western Europe, fluctuating in Central Europe and the Mediterranean.
Widespread and common throughout North America, Europe, and Asia, the Northern Pintail is probably one of the most numerous species of duck worldwide. Numbers in North America vary a great deal from year to year, although some surveys have recorded significant, long-term declines since the 1960s. Predators and farming operations destroy many thousands of Northern Pintail nests each year. Farming has also affected nesting habitat. Pintails appear to be responding to new conservation practices, however, including habitat restoration and tighter restrictions on hunting, and numbers seem to be increasing. If these practices are maintained, Northern Pintails should be able to maintain a healthy population in North America.
Feeding
Aquatic plants and crop vegetative, leaves, stems, roots and seeds. Many terrestrial and aquatic invertebrates, amphibians and some small fish in spring and summer. Feeds by dabbling, upending and head-dipping in shallow water. Sometimes grazes on dry land.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 10,000,000 km². It has a large global population estimated to be 6,100,000-7,500,000 individuals (Wetlands International 2002). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Pairing begins on the wintering grounds and continues through spring migration. Northern Pintails are among the earliest nesters, and arrive on the breeding grounds as soon as they are free of ice (egg laying from november-march) in single pairs or loose groups. The nest is located on dry ground in short vegetation. It is usually near water, but may be up to half a mile away from the nearest body of water. Pintail nests are often more exposed than other ducks' nests. The nest is a shallow depression, built by the female and made of grass, twigs, or leaves, lined with down. Incubation of the 6 to 10 eggs lasts from 21 to 25 days and is done by the female alone. The pair bond dissolves shortly after the female begins incubation, when the males gather in flocks to molt. Within a few hours of hatching, the young follow the female from the nest site. They can feed themselves, but the female continues to tend them until they fledge at 38 to 52 days. In the far north where continuous daylight allows for round-the-clock feeding, the young develop faster. Sexual maturity is reached after one year.
Migration
Highly migratory. Breeders from Iceland winter mainly Britain and Ireland. Breeding populations of north Russia east to north-west Siberia, Fenno-Scandia, and Baltic migrate south-west to winter in the Netherlands and British Isles, movement from former to latter in hard weather. Vast population breeding from Belarus and Russia east to West Siberia winter in Mediterranean and Black Sea areas, and probably West Africa. Major movements away from moult areas and breeding grounds mid-August to early September. Early passage through Europe in August, peak movements mid-September to November, males preceding females due to earlier moult. Further movements under weather influence at any time during winter. Departures from West Africa begin February, from west Europe late February or March; reach tundras late May. Major flyways tend to follow coasts, normally relatively small numbers inland central Europe.
