Appearance:

Very large and heavy bird with heavy bill and rounded tail with straight outer tail-feathers. Both sexes lack wing-bars. Males much bigger than females. Plumage mostly black with brown wings and yellowish bill. Females mottled brown with brick-red breast, throat and chin. Lower back greyish, contrasting with rufous, heavily barred, tail.

Sound:

Display-sounds from male unmistakable. Four phased song: First a slow introductory, double-tapping phase which suddenly bursts into an accelerating crescendo followed by a distinct pop. Then closing with grinding and hissing sounds. Female calls with a deep nasal "kok kok".

Appearance:

Medium sized diving duck. Male all black except orange spot on bill. Female dark brown with contrasting light grey cheeks. Differs from Velvet Scoter in all plumages by lack of white wing-bars, and longer tail. Birds resting on the surface characteristically bow their head when occasionally flapping the wings. Wings held tight against body when diving. Last two characters usable for identification at very long range. Also tend to stay closer together in groups than Velvet Scoter.

Sound:

More vocal than other Scoters. Short, whistling sounds, sometimes reminiscent of a male teal, but a little bit deeper in pitch.
