Melanitta
The scoters are stocky seaducks in the genus ''Melanitta''. The drakes are mostly black and have swollen bills, the females are brown. They breed in the far north of Europe, Asia, and North America, and winter further south in temperate zones of those continents. They form large flocks on suitable coastal waters. These are tightly packed, and the birds tend to take off together. Their lined nests are built on the ground close to the sea, lakes or rivers, in woodland or tundra. These species dive for crustaceans and molluscs. Taxonomy The genus ''Melanitta'' was introduced by the German zoologist Friedrich Boie in 1822. The type species was designated in 1838 as the velvet scoter by Thomas Campbell Eyton. The genus name combines the Ancient Greek ''melas'' meaning "black" and ''netta'' meaning "duck". The genus contains six species: A fossil species, '' Melanitta kirbori'', is known from the Early Pleistocene of Crimea. The presumed fossil "scoter" ''Melanitta ...

Melanitta Perspicillata
The surf scoter (''Melanitta perspicillata'') is a large sea duck native to North America. Adult males are almost entirely black with characteristic white patches on the forehead and the nape and adult females are slightly smaller and browner. Surf scoters breed in Northern Canada and Alaska and winter along the Pacific and Atlantic coasts of North America. Those diving ducks mainly feed on benthic invertebrates, mussels representing an important part of their diet. Taxonomy In 1750 the English naturalist George Edwards (naturalist), George Edwards included an illustration and a description of the surf scoter in the third volume of his ''A Natural History of Uncommon Birds''. He used the English name "The great black duck from Hudson's Bay". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay area of Canada by James Isham. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the 10th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-winged Scoter
The white-winged scoter (''Melanitta deglandi'') is a large Merginae, sea duck. The genus name is derived from Ancient Greek ''melas'' "black" and ''netta'' "duck".

Melanitta Nigra
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 black scoter (''M. americana'') of North America and eastern Siberia was formerly considered to be a subspecies. Taxonomy The common scoter was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Anas nigra''. Linnaeus specified the type locality as Lapland, England. The common scoter is now one of six species placed in the genus ''Melanitta'' that was introduced in 1822 by the German zoologist Friedrich Boie. The genus name combines the Ancient Greek ''melas'' meaning "black" and ''netta'' meaning "duck". The common scoter was formerly considered to be conspecific with the black scoter (''Melanitta americana'') but the two taxa are now treated as separate species. The common scoter is monotypic: no subspecies are recognised. De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Melanitta Americana
The black scoter or American scoter (''Melanitta americana'') is a large sea duck, in length. The genus name is derived from Ancient Greek ''melas'' "black" and ''netta'' "duck". The species name is from the Latin for "American". Together with the common scoter ''M. nigra'', it forms the subgenus ''Oidemia''; the two are sometimes considered conspecific, the black scoter then being referred to as ''M. nigra americana''.

Seaduck
The sea ducks (Mergini) are a tribe of the duck subfamily of birds, the Anatinae. The taxonomy of this group is incomplete. Some authorities separate the group as a subfamily, while others remove some genera. Most species within the group spend their winters near coastal waters. Many species have developed specialized salt glands to allow them to tolerate salt water, but these are poorly developed in juveniles. Some of the species prefer riverine habitats. All but two of the 22 species in this group live in far northern latitudes. The fish-eating members of this group, such as the mergansers and smew, have serrated edges to their bills to help them grip their prey and are often known as "sawbills". Other sea ducks forage by diving underwater, taking molluscs or crustaceans from the sea floor. The Mergini take on the eclipse plumage during the late summer and molt into their breeding plumage during the winter. Species There are twenty-two species in ten genera Genus (; : ge ...

Melanitta Stejnegeri
Stejneger's scoter (''Melanitta stejnegeri''), also known as the Siberian scoter, is a large sea duck. The genus name is derived from Ancient Greek ''melas'' "black" and ''netta'' "duck". Taxonomy Stejneger's scoter was described by the American ornithologist Robert Ridgway in 1887 and given the binomial name ''Oidemia stejnegeri''. The specific name was chosen to honour the Norwegian born ornithologist Leonhard Stejneger. It was formerly considered to be conspecific with the white-winged scoter. It was suggested to be a full species, according to a new study. Description There are a number of differing characteristics of Stejneger's scoter and the white-winged scoter. Males of the white-winged scoter have browner flanks, dark yellow coloration of most of the bill and a less tall bill knob, approaching the velvet scoter. The male Stejneger's scoter has a very tall knob at the base of its mostly orange-yellow bill. The males of both species are very similar and best distinguishe ...

Histrionicus
The harlequin duck (''Histrionicus histrionicus'') is a small sea duck. It takes its name from Harlequin (Italian ''Arlecchino'', French ''Arlequin''), a colourfully dressed character in Commedia dell'arte. The species name comes from the Latin word "histrio", meaning "actor". Other names include painted duck, totem pole duck, rock duck, glacier duck, mountain duck, white-eyed diver, squeaker, lords and ladies 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 ducks, geese and swans in the genus '' A ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
