"Black Scoter," Wikipedia, the free encyclopedia. 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. 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.
