Scooter (bird)
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 farther 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: The presumed fossil "scoter" ''Melanitta ceruttii'', which lived in California during the Late Pliocene, is now placed in the genus ''Histrionicus ...

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''. Its French name, used in parts of its Canadian range, is ''macreuse noire'' (also meaning "black scoter"). The species is listed as Near Threatened by the IUCN. Description This large sea duck is characterised by its bulky shape and large bill. The adult male is all black with a very bulbous bill which is mostly yellow.

This species can be distinguished from other scoters, apart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histrionicus
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 ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

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 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 tenth edition, he placed th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Stejneger's scoter has a very tall knob at the base of its mostly orange-yellow bill. Females are identical in the field. Distribution Stejneger's scoter br ...

Melanitta Fusca
The velvet scoter (''Melanitta fusca''), also called a velvet duck,Buczacki, Stefan (2005) ''Fauna Britannica'', Hamlyn, London. is a large sea duck, which breeds over the far north of Europe and the Palearctic west of the Yenisey basin. The genus name is derived from Ancient Greek ''melas'' "black" and ''netta'' "duck". The species name is from the Latin ''fuscus'' "dusky brown". A small, isolated population nests in eastern Turkey. Stejneger's scoter and the white-winged scoter are sometimes considered conspecific with the velvet scoter, and its two constituent subspecies are then known as ''M. f. stejnegeri'' and ''M. f. deglandi''. Velvet, Stejneger's, and white-winged scoter, along with the surf scoter, are placed in the subgenus ''Melanitta'', distinct from the subgenus ''Oidemia'', black scoter and common scoters. It winters farther south in temperate zones, Europe as far south as Great Britain, and on the Black and Caspian Sea. Small numbers reach France and northern Sp ...
