The black scoter or American scoter (Melanitta americana) is a large sea duck, 43 to 49 cm (17 to 19 in) 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.
This large sea duck is characterised by its bulky shape and large bill. The male is all black with a very bulbous bill which is mostly yellow. The female is a brown bird with pale cheeks, very similar to female common scoter. The adult female averages about 980 g (2.16 lb) and 45 cm (18 in) in length, while the adult male is on average 1,100 g (2.4 lb) and 49 cm (19 in) in length.
This species can be distinguished from other scoters, apart from common scoter, by the lack of white anywhere on the drake, and the more extensive pale areas on the female.
The black scoter and common scoter have diagnosably distinct vocalisations.
The black scoter breeds in the far north of North America in Labrador and Newfoundland to the southeast Hudson Bay. It also occurs on the Siberian side of the Bering Straits east of the Yana River. It winters farther south in temperate zones, on the coasts of the northern USA and Canada, on the Pacific coast south to the San Francisco Bay region and on the Atlantic and Gulf of Mexico coasts, and in Asia as far south as China.
