Physical characteristics
Different from outer geese basically uniform coloration of body and bill, his bill less black marks, sometimes black spots or blotches present on belly. Juvenile generally less strongly patterned dorsally and overall has more mottled plumage. Subspecies rubrirostris has pink bill and paler plumage.
Habitat
Generally associated with water in open country, often with fringe vegetation or near grasslands. Winters in swamps, lakes and coastal lagoons, or on farmland in open country.
Other details
This goose inhabits the temperate and boreal regions of Europe and Asia. The birds visiting the European Union belong more or less to five distinct populations (Scott & Rose). The first population comprises the sedentary birds of north-western Scotland. It has nearly doubled during the last 20 years and is currently amounting to 5250 individuals. The second population is breeding in Iceland and wintering in Scotland, northern England and Ireland. It increased from 25000 in 1950 to 100000 currently. The third population is breeding in Norway, Sweden, Denmark, Western Germany the Netherlands and Belgium, and wintering from the Netherlands to Spain and Morocco. From 30000 at the end of the 1960's, it increased to 200000 currently. The fourth population is breeding in north-eastern Sweden, Finland, the Baltic States and Central Europe, transiting in Italy and wintering in Tunisia and Algeria. It is estimated at 20000 individuals and seems to be quite stable. The fifth population is breeding in the Black Sea regions and Turkey. It reaches northern Greece, and can be estimated at 25000 individuals. Its trends are not well known, but it is probably declining
Feeding
Various plants: roots, leaves, stems and seeds also fruits, grain, potatoes and sprouting cereals in winter,. Forages mostly by grazing on dry land, but also on water, where it sometimes upends.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 1,000,000-10,000,000 km². It has a large global population estimated to be 920,000-970,000 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
Eggs are layed form March-April in loose colonies. Shallow nest of reed stems and grass, lined with down, among reedbeds, on ground or in trees. The Clutch size is 4-6 eggs and incubation lasts 27-28 days. Chicks have brownish olive down yellow below. This Goose reaches sexual maturity in 3 years. Although greylag geese Anser anser establish long-term monogamous pairbonds, some of the existing pairs do split up (divorce) and new pairs are formed during the annual spring mating period.
During the incubation period the gander stays close to the nest, and when the goslings a few days old leave the nest they are cared for by both parents, at this time small family groups may be formed. The gander will aggressively protect goslings and nest and an intruder will be met by hissing and threatening attitudes or may be attacked.
Migration
A few populations sedentary but most birds move southwards to winter in traditional sites at lower latitudes; many European birds follow French coast and concentrate in large numbers, up to 80,000 in Dec/Jan, in Donana marshes, SW Spain. Irregular occurrences often depend on extent of icing during particular winter.

There has been a decline in breeding numbers since the 1970s - 96 pairs were estimated in 1995 and 80 in 1999. Eutrophication of the waters has reduced the species’ food supply which has resulted in poor productivity and juvenile survival. Mink predation has also had a considerable impact during the breeding season, and incubating females have been most vulnerable. However, in recent decades, it has been suggested that birds may be redistributing to other large lakes in western and central Ireland.
Status: Resident and winter visitor from the Continentto all Irish coasts between October and April.
Conservation Concern: Red-listed due to its declining breeding population. The European population has been evaluated as Secure.
Identification: Medium-sized, plump duck usually seen in large flocks offshore. At closer range, males with yellow knob at base of bill. All dark plumage, with no white on the wing. Males black, females sooty brown with paler cheeks.
Similar Species: Velvet Scoter and other ducks.
Call: Soft piping 'pju'.
Diet: During the summer the diet is varied and includes water plants, insect larvae and freshwater crustaceans. During the winter, they forage mostly in waters less than 20 m deep and with coarse sandy substrates. They feed predominantly on benthic bivalve molluscs.
Breeding: First recorded breeding in Ireland in the beginning of the 20th century at Lower Lough Erne. Numbers increased steadily - up to 150 pairs were estimated during the late 1960s. They nest on islands with dense covering of scrub and tree cover. The breedding population has declined since due to the increase in Mink, which predate the nests and young.
Wintering: Common Scoter are almost entirely marine during the winter, and tend to congregate in large flocks on shallow seas with sandy bottoms supporting their preferred prey.
Where to See: Wexford Bay in County Wexford, Castlemaine Harbour & Rossbehy in County Kerry, Brandon Bay - Inner Brandon Bay in County Kerry, Donegal Bay in County Donegal and from Ben Head to Skerries on the east coast are among the best wintering sites, supporting 800-4,500 birds.
Physical characteristics
Black Scoters are large, mostly black or dark gray sea ducks. Formerly called the Common Scoter, the Black Scoter is the least common of the three scoters. Adult males are solid black with a bulbous yellow knob on an otherwise black bill. Females and juveniles are dark gray, lighter on the cheek with a dark cap. Their bills are dark and lack the knob found in adult males.
Scoters spend the non-breeding part of the year in large flocks on the ocean. Black Scoters forage by diving and swimming under water, propelled by their feet. They usually feed in areas of open water, avoiding dense submergent or emergent vegetation. They swallow their prey under water, unless it is large or bulky. They are strong fliers, but must get a running start on the water to get airborne.
Habitat
The breeding range of the Black Scoter is at the edge of the northern forest or in the treeless tundra, where they breed on small, shallow lakes, ponds, sloughs, and river banks with tall grasses to conceal nests. In winter, they can be found on coastal bays and along coastlines, usually in shallow water within a mile of shore.
Português
O ganso-do-egipto (Alopochen aegyptiacus) é uma ave anseriformes do grupo dos gansos. É também conhecido por ganso-do-nilo, ganso-raposo e em Angola por balandira. A sua área de distribuição inclui Europa e África. É especialmente comum a sul do Saara e vale do Nilo.
No século XVIII, a espécie foi introduzida na Grã-Bretanha, onde desenvolveu uma população importante. Esta espécie já colonizou também os Países Baixos, Bélgica, e Alemanha.
Os gansos-do-egipto evitam zonas densamente arborizadas, e podem ser normalmente encontrados em prados, relvados e em campos agrícolas. Passam a maioria do tempo em rios, lagos e terras alagadas. Podem ser encontrados até altitudes elevadas de cerca de 4000 m.
English
The Egyptian Goose (Alopochen aegyptiacus) is a member of the duck, goose and swan family Anatidae. It is in the shelduck subfamily Tadorninae, and is the only extant member of the genus Alopochen. mtDNA cytochrome b sequence data suggest that the relationships of Alopochen to Tadorna need further investigation (Sraml et al. 1996).
This 63-73 cm long species breeds widely in Africa except in deserts and dense forests, and is locally abundant. They are found mostly in the Nile Valley and south of the Sahara. It has also been introduced elsewhere; Great Britain and the Netherlands have self-sustaining feral populations, the former dating back to the 18th century, though only formally added to the British list in 1971. In Britain, it is found mainly in East Anglia, in parkland with lakes.
This is a largely terrestrial species, which will also perch readily on trees and buildings. It swims well, and in flight looks heavy, more like a goose than a duck, hence the English name.
This species will nest in a large variety of situations, especially in holes in mature trees in parkland. Egyptian Geese usually pair for life.
The sexes of this striking species are identical in plumage, though the males average slightly larger. There is a fair amount of variation in plumage tone, with some birds greyer and others browner, but this is not sex or age related.
Egyptian geese typically eat seeds, leaves, grasses, and plant stems. Occasionally, they will eat locusts, worms, or other small animals.
Egyptian geese were considered sacred by the ancient Egyptians, and appeared in much of their artwork.
The Egyptian Goose is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

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.
The Upland Goose or Magellan Goose (Chloephaga picta) is a sheldgoose of the shelduck-sheldgoose subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans. This bird is indigenous to the southern part of South America.

Gadual
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.
Migration
Partially migratory; northernmost breeding birds descend to lower latitudes in winter, but breeders of more temperate regions mostly sedentary.

Order: Anseriformes
Family: Anatidae
Shovelers are specialist filter-feeding waterfowl with a large spoon-shaped or shovel-shaped bill that is almost twice as broad at its tip than at its base and which is the bird’s most conspicuous feature. Fine lamellae extend along most of the edge of the upper mandible and it is by pushing water through this lamellae curtain that small plankton and fine seeds are extracted.
Kuruwhengi are sexually dimorphic. The males are highly coloured most of the year, when they have a blue-grey head and neck with a distinctive white crescentic band at the base of its large spatulate black bill. The breast is a mottled brown and white after breeding but becomes progressively pure white as the nuptial moult proceeds during May. Its chestnut flank is offset by a large white patch at the tail base. The eye is yellow and the legs bright orange. Females are uniformly mottled light brown with dull brown bill and eye, and brown-orange legs. In flight Australasian shovelers have a distinctive profile with a conspicuously large, indeed out of proportion, bill, sharp pointed wings and very rapid wingbeats. The blue, white and green patches on the upper wing contrast with the white underwing. Their flight, especially at takeoff, gives off a distinctive whirring soun. Shovelers are quiet ducks. Displaying or defensive drakes have a rapid, but low volume, train-like sound (chuff-chuff) call, and females sometimes quack. Kuruwhengi are widespread throughout the North and South Islands, rarely on Stewart Island, mainly on large freshwater wetlands (usually fairly coastal), but occasionally in sheltered estuaries. They also make seasonal use of dune lakes, temporary wetlands, drains and sewage ponds.
Shovelers perform spectacular communal courting and then pairs break off to find a secluded territory for nesting which occurs in October, which is later than for all other waterfowl. Males vigorously defend territory. Nests are usually situated in long grass near water. Clutches are of 5-13 (mean 10) white eggs and upon hatching the ducklings are raised solely by the female over about 8 weeks. Broods are rarely active or conspicuous during the day.

Canada Goose,
Order,- Anseriformes, Family,- Anatidae, Species,- Branta canadensis,
The Canada Goose was introduced into England from North America in the seventeenth century. Further introductions in Britain and Ireland as well as in Norway. Sweden and other European countries have resulted in the species becoming naturalised and expanding its range beyond that of the initial introductions, It is found on lakes, pools and ornamental waters especially where grassy banks offer good feeding. The nest-site is usually close to water, often at the base of a tree or on islands where present. The species is colonial, though solitary nests occur, The nest is a mound of grass, reeds and other plant material lined with down lncubation is by the female alone though the male stands guard.
The Canada Goose feeds mainly on plant matter including some aquatic plants. Most of the food is taken on land where shoots, roots, cereals, and seeds form the diet.
The British population is largely resident, though there is a strong moult-migration, particularly from Yorkshire to Invernesshire. Scandinavian breeders move to Germany and the Netherlands in winter, Some wild Canada Geese from North America in very small numbers in Ireland and west Scotland in winter.

Anas strepera
Gadual
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.
Migration
Partially migratory; northernmost breeding birds descend to lower latitudes in winter, but breeders of more temperate regions mostly sedentary.

Light-bellied Brent Goose
Branta bernicla hrota
Cadhan
This population winters almost entirely in Ireland, with small numbers in parts of Britain and France.
Status: Winter migrant from high-Arctic Canada. Most occur in Ireland between October and April.
Conservation Concern: Amber-listed as the majority winter at less than ten sites. The Irish population is also internationally significant, another amber listing criterion. The European population has been evaluated as Vulnerable as several important populations declined.
Identification: Small dark goose, with a black head, neck and breast, and dark-brown upperparts and pale underparts. Almost whitish flanks, and small white crescent on the upperparts of the neck visible at close range.
Similar Species: Dark-bellied Brent Goose, Black Brant, Barnacle Goose
Call: Gutteral 'rhut, rhut'
Diet: During the winter, it feeds mostly on eel-grass, which grows on muddy estuaries, and also on grasslands, usually when coastal supplies have been depleted at estuarine sites.
Breeding: Nests in small, loose colonies by coastal tundra, with pools and small inlets.
Wintering: Mostly found on coastal estuaries during the autumn and early winter, and also on grasslands from mid-winter, until departure for the breeding grounds begins in late April.
Where to See: Highest numbers (c. 30,000) are seen at Strangford Lough in Northern Ireland in October, where most congregate on arrival. Thereafter, they move to other estuarine sites. Lough Foyle in County Derry, Dublin Bay in County Dublin, Tralee Bay, Lough Gill & Akeragh Lough in County Kerry, Rogerstown Estuary in County Dublin, Wexford Harbour & Slobs in County Wexford are other well-used sites (1,000-3,500 birds).
Physical characteristics
The Brant is similar in appearance to the Canada Goose, but smaller and darker. The adult has a gray belly and breast, white rump, and black neck and head with a thin white necklace and no chin-strap.
Fast fliers with swept-back wings, Brant are usually found in a flock. They forage while wading, dabbling in shallow water, or while walking on mudflats or the shore. They display strong site-fidelity to both their wintering and nesting areas.
Habitat
Brant are almost exclusively coastal in their range and are found in shallow bays and saltwater marshes. They nest in the wet, coastal tundra of the high Arctic. Their winter habitat is closely tied to the occurrence of sea grasses and marine algae.
Other details
Branta bernicla is a rare breeder in the European Arctic, but winters mainly in coastal areas of western Europe, which accounts for less than half of its global wintering range. Its European wintering population is large (>240,000 individuals), and increased between 1970-1990. Although a few populations increased or were broadly stable during 1990-2000, key wintering populations (of the subspecies B. b. bernicla) in the United Kingdom, France and the Netherlands declined, and the species underwent a large decline (>30%) overall.
This goose is breeding on the arctic coasts of Eurasia and North America, mainly on small islets protected from polar foxes (Alopex lagopus). It winters along the temperate Atlantic and Pacific coasts. The birds visiting the European Union belong to three different populations (Scott & Rose). The first population, estimated at 20000 individuals, comprises the white-bellied birds of the race hrota, breeding in Greenland and northern Canada and wintering in Ireland. The second population, estimated at 5000 individuals, comprises the birds of the race hrota breeding on Svalbard and wintering in Denmark and north-eastern England. The third population, estimated at 300000 individuals, comprises the dark-bellied birds of the nominate race, breeding along the Russian coasts and wintering in Denmark, Germany, the Netherlands, south-western England and France. All three populations have undergone important fluctuations. The nominate race has experienced a 90% decline during the 1930s following a disease of its foodplant, Zostera marina. It has started to recover since the 1950s, and the increase is still in progress. The populations of Canada and Greenland have increased since the 1960s and seem currently to be stable. The population of Svalbard dropped from about 40000-50000 to a mere 2000 at the end of the 1960s, not only because of the disease of Zostera but also because of non sustainable hunting. Since the 1970s it has recovered
Feeding
Historically, Brant fed almost exclusively on eelgrass, which is still strongly preferred when available. Now they also forage on grasslands and have been able to diversify their diet in the absence of eelgrass, although their range is still closely tied to eelgrass. Brant also eat some aquatic invertebrates.
Conservation
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Long-term pair bonds usually form on the wintering grounds. Nesting occurs in loose colonies, on small islands in tundra ponds. The breeding range of the Brant is typically within five miles of the coast. The nest is a shallow bowl of grass and other vegetation, lined with down. The female incubates 3 to 5 eggs for 22 to 24 days. The young leave the nest within a day of hatching, and both parents continue to tend them and lead them to sources of food. During the long days of the high-Arctic summer, the young feed at all hours, and grow quickly. They fledge at 40 to 50 days, but stay with the parents through the first migration.
Migration
Single wholly migratory population. Depart Russian tundras mid-August to 1st week September. Main route west along arctic coasts to White Sea, then overland to Gulfs of Finland and Bothnia. Passage through Baltic mid-September to early October; first arrivals Denmark late September but bulk October. Some stay Denmark and western Germany through November before moving on in colder weather; others go straight to winter quarters in Netherlands, south-east England, and west France, where peak numbers December-February. Return passage begins early March; most leave England and France by mid-April. Spring gatherings in Netherlands, Denmark and western Germany until main departures in mid-May; only stragglers

Order:Anseriformes
Family:Anatidae
Genus:Cygnus
Species:C. cygnus
Binomial name

Eala Ghlórach
Status: Winter visitor to wetlands throughout Ireland from October to April.
Conservation Concern: Amber-listed due to Ireland hosting more than 20% of the European wintering population. Also due to the majority of Whooper Swans wintering at ten or less sites, as well as its very small breeding population. BirdLife International has assessed the European population as Secure.
Identification: Similar to Bewick's Swan, but larger, with longer neck. Yellow and black bill, with the yellow projecting below the nostril.
Similar Species: Mute and Bewick's Swans.
Call: Vocal bugling or honking.
Diet: Aquatic vegetation, but they are increasingly being recorded grazing on grass in pasture and spilt grain, as well as potatoes from cultivated land.
Breeding: Open shallow water, by coastal inlets, estuaries and rivers. The population occurring in Ireland breeds in Iceland.
Wintering: Most on lowland open farmland around inland wetlands, regularly seen while feeding on grasslands and stubble.
Where to See: Relatively widespread, especially north and west of a line between Limerick and Dublin. Lough Swilly & River Foyle (Co. Donegal) and Lough Foyle on the Donegal/Derry boundary, Lough Gara (Co. Sligo) and the Lough Oughter wetland complex all support greatest numbers (400-2,000 birds).

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.

Anas rubripes
The American black duck (Anas rubripes) is a large dabbling duck in the family Anatidae. It was described by William Brewster in 1902. It is the heaviest species in the genus Anas, weighing 720–1,640 g (1.59–3.62 lb) on average and measuring 54–59 cm (21–23 in) in length with a 88–95 cm (35–37 in) wingspan. It somewhat resembles the female mallard in coloration, but has a darker plumage. The male and female are generally similar in appearance, but the male's bill is yellow while the female's is dull green with dark marks on the upper mandible. It is native to eastern North America. During the breeding season, it is usually found in coastal and freshwater wetlands from Saskatchewan to the Atlantic in Canada and the Great Lakes and the Adirondacks in the United States. It is a partially migratory species, mostly wintering in the east-central United States, especially in coastal areas.
It interbreeds regularly and extensively with the mallard, to which it is closely related. The female lays six to fourteen oval eggs, which have smooth shells and come in varied shades of white and buff green. Hatching takes 30 days on average. Incubation usually takes 25 to 26 days, with both sexes sharing duties, although the male usually defends the territory until the female reaches the middle of her incubation period. It takes about six weeks to fledge. Once the eggs hatch, the hen leads the brood to rearing areas with abundant invertebrates and vegetation.
The American black duck is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). It has long been valued as a game bird. Habitat loss due to drainage, global warming, filling of wetlands due to urbanization and rising sea levels are major reasons for the declining population of the American black duck. The United States Fish and Wildlife Service has been purchasing and managing the habitat of this species in many areas to support the migratory stopover, wintering and breeding populations. The Atlantic Coast Joint Venture also protects habitat through restoration and land acquisition projects, mostly within their wintering and breeding areas.

El ánade real, ánade azulón o pato de collar/ Mallard (Anas platyrhynchos) es una especie de ave anseriforme de la familia Anatidae. Es un ánade de superficie muy común y extendido por el hemisferio norte.
Los ánades reales hibridan con sus parientes más cercanos dentro del género Anas, como el ánade sombrío, y con algunas especies más alejadas como el ánade rabudo, produciendo diversos híbridos que pueden ser totalmente fértiles.
se alimentan en la superficie del agua, llegando a sumergir medio cuerpo, o pastan cerca de las orillas. Los ánades reales son omnívoros y muy flexibles respecto a sus elecciones alimenticias.
Los ánades reales generalmente forman parejas (en octubre y noviembre en su área autóctona) solo hasta que las hembras ponen los huevos al principio de la primavera.
—————
The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males (drakes) have green heads, while the females (hens) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers.

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.
Adults are white all over and young birds greyish with a pinkish bill. Compared to the similar whooper swan, these swans have proportionally more black and less yellow on their bill. They're also smaller than both mute and whooper swans and have faster wingbeats.

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 are other well-used wintering sites.
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
Feeding
Eiders feed during the day by diving to the bottom in waters from 3 to 20 m deep to take mussels, clams, scallops, sea urchins, starfish, and crabs, which are swallowed whole and crushed in the large gizzard.
In winter, when daylight is short, more than half the daytime hours are spent in feeding. The ducks feed in shoal waters off headlands and offshore islands and skerries. Flocks move together at the same rate, the ducks at the front of a flock diving first and the rest following sequentially. After 15 to 30 minutes of intensive feeding, flocks move offshore to rest, preen, and digest the contents of the gullet. The feeding sequence is then repeated.
During spring migration, and when the eider ducks arrive near their breeding places, much time is spent feeding, and the birds accumulate fat. These stores are particularly important for the breeding females, or hens, which rely on the reserves through the incubation period. Unlike many ducks, the hen does not feed once she starts sitting on her eggs. The young apparently eat insects during their first week of life.
Conservation
This species has a large range, with an estimated global Extent of Occurrence of 100,000-1,000,000 km². It has a large global population estimated to be 2,500,000-3,600,000 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
Eiders return to the breeding islands along the northern coasts as soon as shore-fast ice or pack ice starts to dissipate. Many eider ducks are paired when they arrive on the breeding grounds, although some pairing occurs there. Some races remain paired for several years, others do not. Courtship is very intense in spring, with males making displays for the females which include the upward tossing of the head, cooing, neck-stretching and wing-flapping. Courtship continues after pairing in order to maintain pair bonds.
Some female eiders may breed in their second year of life, but males do not breed until they are three years old. Many females will not breed in some years. Common Eiders breed mainly on small offshore marine islands or isolated spits and points that are free of mammalian predators. Within a couple of weeks of arriving at the breeding grounds, the birds make prospecting flights and visits to choose a suitable nesting place. Often females will use the same nesting site for a number of years, while others choose new nest sites each year. They nest in early summer in dense colonies of tens to 10 000 or more; nesting starts progressively later as one proceeds farther north. There is one brood per season.
Only the female prepares the nest. In some races, the male stays with the female for a while; in others, he does not. When he remains, the male defends the female from other eiders and from gulls and ensures that she does not mate with other males.
The female begins laying the eggs a couple of days after the nest is ready. There are usually four or five eggs per nest, and generally, one egg is laid per day. When the second or third egg has been laid, the female lines her nest with down plucked from her body. While laying the egges, some females will leave the nesting colony, possibly to feed before they return to the nest to incubate, or sit on the eggs, continuously. Once incubation begins, the female only leaves the nest for a little as five minutes every two or three days to drink, but not to eat. During early egg-laying, if the male is still in the vicinity, he accompanies the female on her breaks. By mid-incubation, most males have left the colony on their moult migrations. Incubation lasts from 21 to 24 days, and about 50 to 70 percent of the eggs hatch successfully.
The downy newborns leave the nest within 24 hours, and they feed themselves. Within one hour of entering the water, they can dive competently. Young first fly when they are 60 days old. Generally, few survive to fly; many are lost to predators, exposure, or starvation in their first week of life. In good years, one duckling per adult pair may survive for the fall flight. On the other hand, adults are often long--lived, and estimated annual survival rates vary from 80 to 95 percent. This low reproductive success, which is compensated by high adult survival, is very characteristic of eiders and other sea ducks such as scoters and Long-tailed Ducks. Most other ducks breed more successfully but lose 40 to 50 percent of adults each year.
The mother's relationship with her ducklings ends when she leaves for the moult migration in the autumn. In the fall migration, groups of young may travel together and arrive before the adults on the winter range.
Migration
Migratory, partially migratory, and dispersive. In north-west Europe, major moult migration considerably affects picture of normal migration. Breeders and immatures leave nesting grounds for annual moult in German Waddenzee area, leaving ducklings in care of small number of adults which moult locally. First move June, probably mostly immatures, adults following July; some movement as late as September, especially from east. Waddenzee moulting place for virtually all Shelduck in north-west Europe, except for several thousand which moult in Britain, notably in Bridgwater Bay, south-west England. When moult completed, autumn migration begins in rather leisurely fashion. For breeders of Netherlands, Britain, and Ireland, this entails return to breeding areas. Breeding populations from areas to east of moulting grounds winter around coasts of southern North Sea, west France, and to some extent Britain and Ireland; many thousands remain on moulting grounds. Those wintering outside their breeding areas begin return March. Breeding populations of south-east Europe mainly sedentary, flocking in winter, moving only if bad weather. Those breeding Volga area and Ural steppes migrate to Caspian, where join resident breeders. South of main wintering areas, small numbers occur fairly regularly Iberia, Mediterranean basin east to Nile valley and Middle East.

There has been a decline in breeding numbers since the 1970s - 96 pairs were estimated in 1995 and 80 in 1999. Eutrophication of the waters has reduced the species’ food supply which has resulted in poor productivity and juvenile survival. Mink predation has also had a considerable impact during the breeding season, and incubating females have been most vulnerable. However, in recent decades, it has been suggested that birds may be redistributing to other large lakes in western and central Ireland.
Status: Resident and winter visitor from the Continentto all Irish coasts between October and April.
Conservation Concern: Red-listed due to its declining breeding population. The European population has been evaluated as Secure.
Identification: Medium-sized, plump duck usually seen in large flocks offshore. At closer range, males with yellow knob at base of bill. All dark plumage, with no white on the wing. Males black, females sooty brown with paler cheeks.
Similar Species: Velvet Scoter and other ducks.
Call: Soft piping 'pju'.
Diet: During the summer the diet is varied and includes water plants, insect larvae and freshwater crustaceans. During the winter, they forage mostly in waters less than 20 m deep and with coarse sandy substrates. They feed predominantly on benthic bivalve molluscs.
Breeding: First recorded breeding in Ireland in the beginning of the 20th century at Lower Lough Erne. Numbers increased steadily - up to 150 pairs were estimated during the late 1960s. They nest on islands with dense covering of scrub and tree cover. The breedding population has declined since due to the increase in Mink, which predate the nests and young.
Wintering: Common Scoter are almost entirely marine during the winter, and tend to congregate in large flocks on shallow seas with sandy bottoms supporting their preferred prey.
Where to See: Wexford Bay in County Wexford, Castlemaine Harbour & Rossbehy in County Kerry, Brandon Bay - Inner Brandon Bay in County Kerry, Donegal Bay in County Donegal and from Ben Head to Skerries on the east coast are among the best wintering sites, supporting 800-4,500 birds.
Physical characteristics
Black Scoters are large, mostly black or dark gray sea ducks. Formerly called the Common Scoter, the Black Scoter is the least common of the three scoters. Adult males are solid black with a bulbous yellow knob on an otherwise black bill. Females and juveniles are dark gray, lighter on the cheek with a dark cap. Their bills are dark and lack the knob found in adult males.
Scoters spend the non-breeding part of the year in large flocks on the ocean. Black Scoters forage by diving and swimming under water, propelled by their feet. They usually feed in areas of open water, avoiding dense submergent or emergent vegetation. They swallow their prey under water, unless it is large or bulky. They are strong fliers, but must get a running start on the water to get airborne.
Habitat
The breeding range of the Black Scoter is at the edge of the northern forest or in the treeless tundra, where they breed on small, shallow lakes, ponds, sloughs, and river banks with tall grasses to conceal nests. In winter, they can be found on coastal bays and along coastlines, usually in shallow water within a mile of shore.
