Physical characteristics

Medium-sized, rather compact, rather short-billed and short-necked, essentially pinkish-grey goose, with dark, round head and foreneck and pale forewing obvious in flight. Bill marks and legs pink.

Habitat

Concentrated largely in the Atlantic sector of west Palearctic. The presence in breeding habitat (up to 700 m above sea) is limited to brief and uncertain ice-free period. Strict attachment to parts of apparently suitable terrain, at mean densities above 130 nests per square km. Preference in Iceland for inaccessible nest-sites in river gorges suggests safety from ground predators is a primary requirement. Apparent inconsistency of wide-spread grouping of oasis nests on low heathy mounds or ridges perhaps due to relative failure of such predators to reach these seasonally uninhabitable uplands. In Spitsbergen, where predation of Arctic Fox is minimal, nest on flat ground or grassy slopes when snow-free at laying time, as well as low cliffs and rock outcrops.

Other details

Anser brachyrhynchus breeds only in Svalbard, Iceland and east Greenland, with the entire global breeding range hence confined to Europe. The European breeding population is relatively small (<69,000 pairs), but increased substantially between 1970-1990. All three populations continued to increase during 1990-2000, and the species underwent a moderate increase overall.

This goose has two distinct populations. Both have undergone an important increase since the 1950's. The first population is breeding in Iceland and Greenland, and wintering in Scotland and northern England. It amounts to 225000 individuals. The second population is breeding on Svalbard and wintering in Denmark, the Netherlands and Belgium. It amounts to 34000 individuals

Feeding

Vegetable material, including parts of plants both above and below ground. Feeds like Greylag Goose, though much less commonly in water, and smaller Bill and gizzard tend to restrict it to softer material. In summer quarters, eats green parts, roots, and fruits of wide variety of tundra plants. In winter quarters, now feeds mainly on farmland, including grassland, but exact composition of diet differs according to local, seasonal, and annual variations in crop-plant availability.

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 280,000 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

Egg-laying in Iceland from early or mid-May, in Spitsbergen laying starts last half May and completed first half June. The nest is build in low hummocks and banks snow-free at time of building, and above post-thaw floods. Also tops of rock outcrops, ledges on river gorge cliffs, and tops of rock pinnacles in gorges. The nest consists of low mound of grasses, sedges and other vegetation, with shallow cup. Large amounts of down added during and after laying. Clutch is usually usually 3-6, incubation lasts 26-27 days and the goslings will flegde after about 56 days.

Migration

Migratory, Greenland and Icelandic populations winter mostly in Scotland and N and E England; Svalbard birds winter along E shores of N Sea. Sporadically in more southern latitudes during cold winters.

Lockdown walk in Parc Roi Baudouin - Koning Boudewijnpark

en.wikipedia.org/wiki/Egyptian_goose

King Baudouin Park was created in 1977 in order to protect one of the last remaining examples of the natural landscape of Brabant in the Brussels Region. This initiative also enabled the creation of a landscape extending over more than 100 hectares and bringing together the magnificent beech woods of Laerbeek, Poelbos and Dieleghem, with meadows, marshland, ponds and grassy expanses. In the lower section, an English-style Romantic landscaped park was developed; this encompasses the garden of the Institut du Sacré-Cœur and the floor of the Molenbeek Valley. Wide lawns bordered by flowerbeds, isolated trees, water features and beds of great mannagrass, home to frogs, newts, common reed buntings, Eurasian reed warblers and numerous fish, surround a watermill fish pond, one of the last remaining vestiges of the Abbey of Dieleghem. Higher up, hedgerows of hazel bush, holly, hawthorn, blackthorn and hornbeam encircle the remaining pastureland, orchard, vegetable gardens and fields of crops, recreating a unique bucolic atmosphere on the edge of the city. A neo-Norman style cottage, built in 1908 by the Liège-based architect Charles Castermans for the lawyer Eugène Van den Elschen, now houses a café, a popular stopping point for walkers.

Breeding

incubation min.: 24 days

incubation max.: 26 days

fledging min.: 45 days

fledging max.: 50 days

broods 1

eggs min.: 8

eggs max.: 12

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.

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.

Long-tailed Duck (Clangula hyemalis) 02 "Move move, the sky is falling" - Water Birds of Western NY by Adventure George

Long-tailed Duck Clangula hyemalis, hens divers, medium size seaducks

Order: Anseriformes

Family: Anatidae

Status: Fairly common winter coast. Rare east.

++++++++++++++++

Formerly known as Oldsquaw, the Long-tailed Duck breeds in the Arctic and winters along both coasts of North America. It is distinctive among ducks in plumage, molt sequences, foraging behavior, and vocalizations. www.allaboutbirds.org/guide/Long-tailed_Duck/id

A duck of cold northern waters. Often the most abundant bird in the high Arctic. Large flocks are often far out at sea; many spend the winter on such northern waters as Bering Sea, Hudson Bay, and Great Lakes. Flocks fly low over sea, with stiff shallow wingbeats, often tilting from side to side. Far more vocal than most ducks, and loud melodious calls of flocks can be heard from some distance. It was formerly called "Oldsquaw," not politically correct by any measure, a reference to this "talkative" behavior -- although it is the male of this species that makes most of the noise. +++ Feeding Behavior

forages by diving and swimming underwater, with wings partly opened but propelled mainly by feet. Most feeding is within 30' of surface; supposedly able to dive more than 200', deeper than any other duck.

Status: Resident at larger lakes in Counties Wicklow and Donegal. Rare winter visitor throughout Ireland.

Conservation Concern: Amber-listed in Ireland, due to its small breeding population. The European population has been assessed as Secure.

Identification: Large, long-bodied, with a long narrow red bill ending in a hook. Swimming birds often retract their long necks. Adult males largely white with glossy green-black neck and head. Back largely black. Females with dark red-brown head, though with a white throat patch, greyish body.

Similar Species: Red-breasted Merganser.

Call: Male call is deep muffled 'krroo-krraa'.

Diet: Goosanders feed largely on small and medium sized fish, and occasionally larger fish such as Pike.

Breeding: Breed on freshwater lakes and pools and winter on large unfrozen lakes and brackish lagoons and occasionally on coastal estuaries. The most recent breeding records in Ireland come from County Wicklow, where one pair was confirmed breeding in 1994, and annual breeding has since been deemed likely, though not confirmed.

Wintering: Irish birds appear to be largely resident. Birds from Continental Europe can occasionally found along coastal areas in winter.

Where to See: Found on freshwater. Belfast Lough in County Down and Lough Tay & Lough Dan in County Wicklow are the most regularly used wintering areas.

Physical characteristics

The long, narrow bill with serrated edges readily distinguishes mergansers from all other ducks. Common mergansers are among the largest ducks, but are less stocky than eiders and goldeneyes. In flight, they appear more elongated than other ducks, flying in trailing lines close to the water surface.

Male common mergansers have a greenish-black crested head and upper neck. The lower neck, breast, and underparts are creamy-white with a variable pink wash. They have black backs and upperwing coverts with white scapulars. The bill is red with a blackish culmen and nail. The legs and feet are deep red.

Female common mergansers have a tufted red-brown head that is clearly defined from the lower neck by a clear whitish chin. The back and sides are silver-gray and the breast and belly are white. The bill is red with a blackish culmen and nail. The legs and feet are deep red.

Habitat

Common mergansers nest in tree cavities, nest boxes, cliff crevices, and on the ground generally near clear water rivers in forested regions and mountainous terrain. They feed by diving underwater in marine and freshwater habitats.

Other details

This duck has a wide distribution in boreal and temperate regions of Eurasia and North America. It has also isolated populations in the mountainous regions of the Alps, the Caucasus and Tibet. Two populations inhabit or visit the European Union. One comprises the birds of northern and north-western Europe, wintering mainly in the Baltic Sea and around the North Sea. It amounts to about 200000 individuals, and seems stable. The birds of the British Isles are sedentary. They amount to about 5000-8000 individuals and increased during the last decades. The population of Central Europe (France, Germany) amounts to 3000 individuals. It is also sedentary and seems to be slightly increasing. A very small population is breeding in the Balkan Peninsula. It is estimated at not more than 11-32 breeding pairs, and its trends are unknown

Feeding

Common mergansers eat mainly fishes, amphibians, crustaceans, mollusks, and other invertebrates obtained by diving underwater in marine and freshwater habitats

Breeding

Common mergansers breed from Alaska, the southern Yukon, Labrador, and Newfoundland south to central California, Arizona, New Mexico, southern Chihuahua, and, east of the Rockies, to Minnesota, Michigan, New York, New England, and Nova Scotia. Common mergansers nest in tree cavities, nest boxes, cliff crevices, and on the ground generally near clear water rivers in forested regions and mountainous terrain. Female common mergansers lay an average of 9 to 12 eggs.

Migration

Migratory and partially migratory. No evidence that any Icelandic breeders emigrate. Similarly, British breeders almost entirely resident, moving short distances (mainly within 150 km) from breeding waters to lakes and sheltered estuaries. No evidence that breeders of southernmost Scandinavia, north Germany, and Poland move further than western Baltic, but those breeding central and northern Scandinavia, Finland, Baltic States, and Russia east to Pechora migrate west to Baltic and beyond to Netherlands and Britain, in smaller numbers to west France and north Spain. In late August and early September, moulting and breeding waters often deserted as flocks build up on estuaries and shallow parts of some inland lakes. Mass departures not until advent of freezing; thus major movements through Russia and Baltic October and early November. Early arrivals in North Sea countries late October and early November, but no large numbers until December, while numbers build up on Black Sea and Sea of Azov from mid-October to mid-December. Return migration from early March and, apart from stragglers, non-breeding range vacated by mid-April.

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

Ganso-do-egito by Rodrigo Soldon Souza

Parque do Ibirapuera São Paulo Brasil

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.

---------------------------------------------

he 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).

Two or three species of Alopochen from the Madagascar region have become extinct in the last 1000 years or so:

Mauritian Shelduck, Alopochen mauritianus - Mauritius, late 1690s

Malagasy Shelduck or Madagascar Shelduck, Alopochen sirabensis (may be subspecies of A. mauritianus) - Madagascar, prehistoric: see Late Quaternary prehistoric birds

Réunion Shelduck or Kervazo's Egyptian Goose, Alopochen kervazoi - Réunion, c.1690s

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, the Netherlands and Germany have self-sustaining feral populations, the British population 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. It was officially declared a pest in the UK in 2009.[1]

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.[citation needed]

This species will nest in a large variety of situations, especially in holes in mature trees in parkland. The female builds the nest from reeds, leaves and grass, and both parents take turns incubating eggs.[2] 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. A large part of the wings of mature birds is white, but in repose the white is hidden by the wing coverts. When it is aroused, either in alarm or aggression, the white begins to show. In flight or when the wings are fully spread in aggression the white is conspicuous. The voices and vocalisations of the sexes differ, the male having a hoarse, subdued duck-like quack which seldom sounds unless it is aroused. The male Egyptian goose attracts its mate with an elaborate, noisy courtship display that includes honking, neck stretching and feather displays.[2] The Female has a far noisier raucous quack that frequently sounds in aggression and almost incessantly at the slightest disturbance when tending her young. Both sexes are aggressively territorial towards their own species when breeding and frequently pursue intruders into the air, attacking them in aerial "dogfights".[3]

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.

Its generic name looks like Greek ἀλώπηξ + χήν = "fox-goose", referring to the colour of its back, but with a Greek language error: the linguistically correct form would have been *Alopecchen or *Alopecochen.

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).
