The Black or American Scoter (Melanitta americana) is a large sea duck, 43 to 49 centimeters in length. 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 adult female averages about 980 grams (2.1 lbs.) and 45 cm (18 inches) in length, while the adult male is on average 1100 grams (2.4 lbs.) and 49 cm (19 inches) in length. It 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. This is America's only black duck, although the female may have some yellow around the nostils. When this bird is in flight, there is a silvery appearance from the underside.
