Common Goldeneye
The common goldeneye or simply goldeneye (''Bucephala clangula'') is a medium-sized sea duck of the genus ''Bucephala'', the goldeneyes. Its closest relative is the similar Barrow's goldeneye. The genus name is derived from the Ancient Greek ''boukephalos'' ("bullheaded", from ''bous'', "bull " and ''kephale'', "head"), a reference to the bulbous head shape of the bufflehead. The species name is derived from the Latin ''clangere'' ("to resound"). Common goldeneyes are aggressive and territorial ducks, and have elaborate courtship displays. Description Adult males ranges from and weigh approximately , while females range from and weigh approximately . The common goldeneye has a wingspan of 30.3-32.7 in (77-83 cm). The species is named for its golden-yellow eye. Adult males have a dark head with a greenish gloss and a circular white patch below the eye, a dark back and a white neck and belly. Adult females have a brown head and a mostly grey body. Their legs and feet are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada Goose
The Canada goose (''Branta canadensis''), or Canadian goose, is a large wild goose with a black head and neck, white cheeks, white under its chin, and a brown body. It is native to the arctic and temperate regions of North America, and it is occasionally found during migration across the Atlantic in northern Europe. It has been introduced to the United Kingdom, Ireland, Finland, Sweden, Denmark, New Zealand, Japan, Chile, Argentina, and the Falkland Islands. Like most geese, the Canada goose is primarily herbivorous and normally migratory; often found on or close to fresh water, the Canada goose is also common in brackish marshes, estuaries, and lagoons. Extremely adept at living in human-altered areas, Canada geese have established breeding colonies in urban and cultivated habitats, which provide food and few natural predators. The success of this common park species has led to its often being considered a pest species because of its excrement, its depredation of crops, its n ...

King Eider
The king eider (pronounced ) (''Somateria spectabilis'') is a large sea duck that breeds along Northern Hemisphere Arctic coasts of northeast Europe, North America and Asia. The birds spend most of the year in coastal marine ecosystems at high latitudes, and migrate to Arctic tundra to breed in June and July. They lay four to seven eggs in a scrape on the ground lined with grass and down. Taxonomy and etymology When he first described the king eider in 1758, in the 10th edition of his opus Systema Naturae, Carl Linnaeus assigned it to the genus ''Anas'', along with the rest of the ducks. In 1819, William Elford Leach moved it and the other large eiders to the genus ''Somateria'', where it has remained since. It is very closely related to the other members of its genus, and is known to hybridise with the common eider. Despite its very large range, it is monotypic. The genus name ''Somateria'' is a combination of the Greek words ''sōma'', meaning "body", and ''erion'', meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harlequin Duck
The harlequin duck (''Histrionicus histrionicus'') is a small sea duck. It takes its name from Harlequin (French ''Arlequin'', Italian ''Arlecchino''), a colourfully dressed character in Commedia dell'arte. The species name comes from the Latin word "histrio", meaning "actor". In North America it is also known as lords and ladies. Other names include painted duck, totem pole duck, rock duck, glacier duck, mountain duck, white-eyed diver, squeaker and blue streak. Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the harlequin duck in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The Dusky and Spotted Duck". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from Newfoundland in eastern Canada. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the harlequin duck with the du ...

Green-winged Teal
The green-winged teal (''Anas carolinensis'') is a common and widespread duck that breeds in the northern areas of North America except on the Aleutian Islands. It was considered Conspecificity, conspecific with the Eurasian teal (''A. crecca'') for some time, but has since been split into its own species. The American Ornithological Society continues to debate this determination, however nearly all other authorities consider it distinct based on behavioral, morphological, and molecular evidence. The scientific name is from Latin ''Anas'', "duck" and ''carolinensis'', "of Province of Carolina, Carolina". This dabbling duck is strongly bird migration, migratory and winters far south of its breeding range. It is highly gregarious outside of the breeding season and will form large flocks. In flight, the fast, twisting flocks resemble waders. Taxonomy The green-winged teal was Species description, formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revi ...

Greater Scaup
The greater scaup (''Aythya marila''), just scaup in Europe or, colloquially, "bluebill" in North America, is a mid-sized diving duck, larger than the closely related lesser scaup. It spends the summer months breeding in Alaska, northern Canada, Siberia, and the northernmost reaches of Europe. During the winter, it migrates south to the coasts of North America, Europe, and Japan. Drake greater scaup are larger and have more rounded heads than the females; they have a bright blue bill and yellow eyes. Their heads are dark, with a green gloss; the breast is black, the belly white and the wing shows a white stripe. The females are mostly brown, again with white on the wing. They have dull blue bills and white on the face. Greater scaup nest near water, typically on islands in northern lakes or on floating mats of vegetation. They begin breeding at age two, but start building nests in the first year. The drakes have a complex courtship, which takes place on the return migration to ...

Gadwall
The gadwall (''Mareca strepera'') is a common and widespread dabbling duck in the family Anatidae. Taxonomy The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus ''Mareca''. There are two subspecies: * ''M. s. strepera'', the common gadwall, described by Linnaeus, is the nominate subspecies. * ''M. s. couesi'', Coues's gadwall, extinct 1874, was formerly found only on Teraina, a coral atoll in the Pacific Ocean. The specific name ''strepera'' is Late Latin for "noisy". The etymology of the word ''gadwall'' is not known, but the name has been in use since 1666. Description The gadwall is long with a wingspan. The male is slightly larger than the female, weighing on average against her . The breeding male is patterned grey, with a black re ...

Common Scoter
The common scoter (''Melanitta nigra'') is a large sea duck, in length, which breeds over the far north of Europe and the Palearctic east to the Olenyok River. The genus name is derived from Ancient Greek ''melas'', "black", and ''netta'', "duck". The species name is from Latin ''niger'' "shining black". The black scoter (''M. americana'') of North America and eastern Siberia is sometimes considered a subspecies of ''M. nigra''. Description It is characterised by its bulky shape and large bill. The male is all black with a bulbous bill which shows some yellow coloration around the nostrils. The female is a brown bird with pale cheeks, very similar to female black scoter. This species can be distinguished from other scoters, apart from black scoter, by the lack of white anywhere on the drake and the more extensive pale areas on the female. Vocalisations Black scoter and common scoter have diagnosably distinct vocalisations. Ecology It winters farther south in temperate zones, ...

Common Loon
The common loon or great northern diver (''Gavia immer'') is a large member of the loon, or diver, family of birds. Breeding adults have a plumage that includes a broad black head and neck with a greenish, purplish, or bluish sheen, blackish or blackish-grey upperparts, and pure white underparts except some black on the undertail coverts and vent. Non-breeding adults are brownish with a dark neck and head marked with dark grey-brown. Their upperparts are dark brownish-grey with an unclear pattern of squares on the shoulders, and the underparts, lower face, chin, and throat are whitish. The sexes look alike, though males are significantly heavier than females. During the breeding season, loons live on lakes and other waterways in Canada; the northern United States (including Alaska); and southern parts of Greenland and Iceland. Small numbers breed on Svalbard and sporadically elsewhere in Arctic Eurasia. Common loons winter on both coasts of the US as far south as Mexico, and on ...

Common Eider
The common eider (pronounced ) (''Somateria mollissima''), also called St. Cuthbert's duck or Cuddy's duck, is a large ( in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to . The eider's nest is built close to the sea and is lined with eiderdown, plucked from the female's breast. This soft and warm lining has long been harvested for filling pillows and quilts, but in more recent years has been largely replaced by down from domestic farm-geese and synthetic alternatives. Although eiderdown pillows or quilts are now a rarity, eiderdown harvesting continues and is sustainable, as it can be done after the ducklings leave the nest with no harm to the birds. Taxonomy The common eider was formally named by the Swedish naturalist Carl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
