Appearance:

Slightly smaller than Eider. Male at close range unmistakable. At a distance the black back is diagnostic. Female similar to female Eider, but feathering on bill is not reaching nostrils, giving the bird a peculiar "smile". Head shape is less triangular with a steeper forehead, and nail of bill is black. V-shaped barring on flanks.

Sound:

Male: Calls similar to Eider but easily distinguished by the vibrating quality. A "aaaooooooh" (shorter in duration than Eider) Starting on a low note, slowly ascending and ending on a descending note with a distinct vibrato/pulse. Often in the form of three calls: "oohh, a-ohhh hahahaoohohohoh". Usually accompanied by the female "ga ga ga ga".

Large dabbling duck. In all plumages distinguished from other dabbling ducks by its slim neck and elegancy.

Female mostly brown, wattled plumage, with longer tail than other dabbling duck females. Both sexes with bluish bill. Speculum dark green with broad white rear edge. Front edge buff in males. Edges more prominent in flight than the actual speculum. Flight pattern closer to Wigeon than Mallard.

Sound:

Female: similar to Mallards coarse laughing sound, but with a more emphasized first "haaa", and a more silent accelerating subsequent "laugh". Male: Pleasant, resonant "plop" similar to Teal, but lower pitched, richer, mellower and not so metallic. Accompanied by a higher pitched, slightly raspy whistling "aiiooo" rising and falling in pitch.
