[order] ANSERIFORMES | [family] Anatidae | [latin] Anser caerulescens | [UK] Snow Goose | [FR] Oie de neiges | [DE] Schneegans | [ES] Ganso Azul | [NL] Sneeuwgans
Physical characteristics
The Lesser Snow Goose Chen caerulescens caerulescens has two different appearances, white phase and blue phase. The plumage of white-phase geese is almost completely white, except for black wing tips. The blue-phase goose has a white head, a bluish colour on the feathers of the lower back and flanks, and a body that ranges in colour from very pale, almost white, to very dark. Both the white- and blue-phase snow geese frequently have rusty orange faces, because their feathers have been stained by iron in the earth where the birds feed.
The goslings of the white-phase geese are yellow, those of the blue phase nearly black. By two months of age the young birds of both colour phases are grey with black wing tips, although the immature blue-phase birds are generally a darker grey and have some light feathers on the chin and throat, which can become stained like those of the adults. The goslings are still grey the following spring; in April and May they show white scapulars, or feathers close to where the wing joins the body, white necks, and white secondary coverts, or feathers covering the base of the flight feathers. They still have an overall grey wash.
By the spring the black to dark grey bills of the immature birds have become grey-pink. The bill of the adult is pink and is narrower than the broad, black bill of the Canada Goose. It has evolved to enable the geese to eat the nutritious roots of marshland plants. The serrated edge of the bill makes the bird appear to be smiling and is sometimes called the "grinning patch." The Lesser Snow Goose has a wingspan of about 90 cm and its average weight is 2.2 to 2.7 kg, the male being larger.
There are two other types of white geese found in North America: the Greater Snow Goose Chen caerulescens atlantica, and Ross' Goose Chen rossii. The Greater Snow Goose is slightly larger than the Lesser Snow Goose and nests farther north and east; blue-phase Greaters are rarely seen. The Ross' Goose is much smaller than the Lesser Snow Goose and does not have a grinning patch on the side of the bill. Blue-phase Ross' Geese are rare. As the numbers and ranges of both species have increased during the last 50 years, hybrids between them have become quite frequent. The hybrids are intermediate in size between Ross' Geese and Lesser Snow Geese.

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.

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.

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,

El chajá moñudo, a pesar de no parecerlo, pertenece al orden de los anseriformes, al igual que los patos y las ocas. Es un ave grande, de hasta 90 cm de altura y de 2 a 5 kg de peso. Presenta unos espolones curvados y puntiagudos en la parte anterior de las alas, de hasta 5 cm de longitud, que utiliza como arma defensiva.
En muchos lugares de Sudamérica, dada su agresividad y una potente voz, se utiliza como animal de vigilancia.

The Greenland White-fronted Goose Anser albifrons flavirostris is one of four subspecies of the Greater White-fronted Goose. The species is fully migratory and is a winter visitor to Ireland from Arctic breeding grounds in Greenland.
The Irish wintering population has very limited geographic range and no overlap with other races, breeding solely in west Greenland, migrating in spring and autumn through south and west Iceland to wintering grounds in Scotland, Wales, and Ireland. The population of Greenland White-front Geese is small and their world range limited.
Greenland White-fronted Geese are categorised as ’Endangered’ using the IUCN‘s global Red List criteria; are listed on Annex I of the EU Directive on the conservation of wild birds. Greenland White-fronted Geese are selected as a conservation interest for a number of Special Protection Area’s in Ireland.
The Greenland White-fronted Goose is confined to roughly 80 regular sites in Ireland and Britain. Because of their high levels of site fidelity, there is limited potential for colonising new areas, re-colonising of deserted sites, or large-scale immigration from other areas to supplement declining flocks although exchange of individuals does occur regularly. The species is highly gregarious outside of the breeding season, with flocks of up to 9,000 individuals known to occur at Wexford Slobs. However, the geese are more commonly observed in small loose groups due to the patchiness of the preferred habitat.
Habitat loss and degradation is a major global threat to Greenland White-fronted Geese. In particular, disturbance by humans, wetland habitat degradation due to drainage, peat-extraction and changing management practices are threats to the feeding and roosting habitats used by this species across its range. Collision impacts with inappropriately located wind energy developments are identified as a potential threat, with a prerogative on appropriate survey and impact assessment .

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.
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.

Physical characteristics
In direct comparison appreciably the Bewick's Swan Cygnus columbianus is smaller (L 120 cm) than Mute Swan (Cygnus olor), with shorter neck, less elongated head shape and less yellow on bill. This species, formerly known as the Whistling Swan, is a large bird with white plumage and black legs, feet, and beak. However, when it is feeding in iron-rich areas, the feathers on its head and neck may take on a reddish tinge.
The male weighs on average 7.5 kg and can measure 1.3 m from bill to tail. The adult female is about the same size as the male but weighs slightly less, about 6.3 kg. The young of the year are smaller than the adults and have grey plumage, pinkish beaks with black tips, and pink legs and feet. It takes at least two years for adult plumage to grow in.
Habitat
Bewick's Swans spend the summer on the tundra of the Canadian Arctic and Alaska. Each pair of Bewick's Swans defends a large territory that may be more than 2 km2.
Other details
This swan is breeding in the Eurasian tundra, from the Finno-Russian border to Central Siberia. The birds breeding West of the Taymyr Peninsula are wintering mainly in Denmark, the Netherlands, England and Ireland. A few birds also reach the Rhone Delta in southern France. Elsewhere the species is of only very occasional occurrence during strong winters. The total population visiting Western Europe is estimated at 17000 individuals, and seems to be stable
Feeding
Bewick's Swans feed mainly on the tubers and roots of aquatic plants that grow at shallow depths in fresh, brackish, or salt water. They reach this food by extending the head and neck downward, frequently tipping the body but seldom completely submerging. On the Atlantic coast the swans vary their diet with molluscs, or hard-shelled water animals, such as mussels and clams. In recent years, they have begun to feed extensively on grains, such as corn and wheat that are left on the ground after the harvest.
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 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
The courtship and pairing of young adult birds is in full swing in late winter and continues through the spring migration. Adults already paired reinforce their bond by vocal and visual displays. The most spectacular of these is the so-called victory display in which male and female face each other, extend and wave the wings slowly, bow the head and neck forward and backward, and, in duet, produce a formalized sequence of loud, melodious sounds. The pair-bond is strong and probably lasts for life.
They are solitary nesters with each pair defending a large territory that may be more than 2 km2. The nest is a large conical affair of sticks, often placed on a hummock and lined with moss, sedges, and grasses. It is usually quite close to a tundra pond or lake that is large enough to provide a good feeding and loafing area for the young but not too large to defend against other breeding pairs. Nests in favourable locations tend to be re-used each year.
Bewick's Swans usually do not breed until their fourth or fifth year. A year before breeding, pairs normally "go steady" and select and defend a territory without actually nesting. When they reach breeding age, they begin to nest in late May or early June before the snow is off the tundra, while many of the lakes are still frozen. The cream-coloured, elliptical-ovate eggs average 107 mm in length. A clutch of four eggs is normal; in exceptionally warm, favourable springs the female often lays five or six eggs. An unusually cold and snowbound spring, on the other hand, may inhibit nesting for that year. Not all adult pairs nest every year.
Incubation, or warming of the eggs until they hatch, begins when the final egg is laid and lasts about 32 days. Only the female incubates the eggs, but the male remains close by, guarding the nest site and defending the territory. If the eggs are destroyed, renesting will not take place.
The downy ash-grey cygnets emerge in early July and weigh about 180 g. They are soon able to hunt for their own food; both parents help them find suitable plant food around the margins of the pond. They need to be brooded, or kept warm by a parent sitting on them, frequently, to protect them from the cold and the onslaughts of numerous mosquitos. The early casualty rate among cygnets is quite high, chiefly due to cold or starvation.
The family remains on the territory during August, when the adults undergo a moult period, or shed feathers. They are flightless for several weeks, until new primary wing feathers replace those that have been shed. If all goes well, the cygnets' growth rate is very rapid and in September, after about 70 days, their weight may be 28 times the hatching weight. This growth rate is necessary, because by early September the cygnets must be fully feathered and able to fly well enough to travel to larger lakes that will freeze over more slowly.
At these lakes they encounter young, non-breeding birds of the previous year and unsuccessful nesters or unpaired adults that have spent the summer in small groups in favourable feeding locations. From these points, the flocks begin the early stages of migration as freeze-up approaches. An early winter will doom cygnets not yet ready to fly out of the north.
Migration
Migratory; winters in temperate areas; sporadically in more southern latitudes during cold winters.

Physical characteristics
The Long-tailed Duck is a distinctive sea duck with a short bill and heavy body. The short, pointed, all-dark wings of the Long-tailed Duck are evident in all sexes and plumages. In breeding plumage, the male has a long, black tail-plume, a white rump and belly, and black breast. The head and back are black, with brown shoulders and a white patch around the eye. In winter the brown on the back is replaced by white, and the head is white with a gray cheek-patch. In spring, the female is gray with a white rump, and white around the eye and at the nape of the neck. In winter, she has a white face with dark crown and cheek-patch. The juvenile is similar to the female--gray with white, although it has more white on its face than the female.
Long-tailed Ducks dive and swim under water, and, while they propel themselves with their feet like other ducks, their wings are sometimes partly opened under water. Most feeding is done within 30 feet of the surface, but they are capable of diving more than 200 feet below the surface. Long-tailed Ducks fly low with stiff and shallow wing-beats, often tilting from side to side.
Habitat
Long-tailed Ducks breed in shallow tundra ponds and lakes. During other seasons, Long-tailed Ducks can be found on the ocean over sandy substrates. They prefer sheltered water, but can be found on the open ocean as well.
Other details
Clangula hyemalis is a widespread breeder in northernmost Europe, which accounts for less than half of its global breeding range. Its European breeding population is large (>690,000 pairs), and was stable between 1970-1990. Although trends in Greenland, Iceland and Sweden during 1990-2000 were unknown, populations were stable elsewhere-including in the Russian stronghold-and the species probably remained stable overall.
This duck has a wide distribution at high latitudes in Eurasia and North America. Most of the birds inhabiting northern Europe are wintering in the Baltic Sea. This population is estimated at 4.5 millions of individuals, but only a few thousand reach the Wadden Sea and only stragglers are recorded more south, especially in hard winters. The birds of Greenland and Iceland reach the west of the British islands. This population is estimated at 150000 individuals. Both populations seems stable (Scott & Rose), despite the fact that some decrease has been reported from Scandinavia and that the bird is sensitive to oil pollution of the s
Feeding
For Long-tailed Ducks at sea, mollusks and crustaceans are the main source of food. In summer, aquatic insects, other aquatic invertebrates, and some plant material are eaten.
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 7,200,000-7,800,000 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
Most female Long-tailed Ducks first breed at the age of two. Pair bonds are established in the winter, or during the spring migration, and last until incubation begins. The nest is located on dry ground close to the water, often hidden in the undergrowth or among rocks. It is a depression lined with plant material and great quantities of down that the female adds to the nest after she begins laying. She usually lays from 6 to 11 eggs and incubates them for 24 to 29 days. Shortly after hatching, the young leave the nest and can swim and dive well. The female tends them and may dislodge food items for them when she is diving, but they feed themselves. They first fly at 35 to 40 days.
Migration
Migratory and partially migratory. winters mainly offshore between 55 degrees North and 75 degrees North and in Baltic Sea. Icelandic breeders are partial migrants, some remaining to winter around coasts, others moving to southern Greenland. Baltic Sea appears to be the most important wintering area in west Palearctic. Though extensive moult migration occurs in east Siberia, in west Palearctic males moult on coasts and lakes close to breeding areas either solitarily or in small flocks. Movements beginning late June to early July. Large flocks build up August-September as females and young desert breeding areas. Some reach south Sweden mid-September, but overland passage from White Sea to Gulf of Finland mostly 1st half October. Main influx to west Baltic November or December. Return movement North and Baltic Seas from mid-March, with major overland passage towards White Sea in May. They return to breeding areas dependent on thaw, late April or early May in Iceland, mid-May to mid-June in Russian tundras.
Hooded Mergansers prefer freshwater habitats like rivers, lakes, and ponds with wooded surroundings. They are particularly fond of areas with plenty of trees for nesting since they nest in cavities.
