Common Scoter
Melanitta nigra
The common scoter is characterised by its bulky shape and large bill. The male is all black with a bulbous bill which shows some yellow coloration around the nostrils. The female is a brown bird with pale cheeks, very similar to female black scoter. This species can be distinguished from other scoters, apart from black 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 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.
