Black Scoter
Melanitta americana
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. 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. Voice: The black scoter and common scoter have diagnosably distinct vocalisations.

The plumage of the male is glossy black with large white wing patches and small white patches behind the eye. The bill is partly orange. The female is similar to the male but lacks the gloss on the feathers and is duller and browner.
