Appearance:

A small and compact duck, more resembling a Goldeneye than other sawbils. Small bill and steep forehead. Male almost completely white, with black mask and fine black markings. In flight the dark wings gives it a more black and white appearance. Female or immature may be mistaken for other small ducks, but combination of brown upper head and white lower head is unique among WP-ducks. Body brownish grey. White patch on wing coverts prominent in flight in both sexes. Groups fly in loose lines, not bunches.

Sound:

Mostly quiet except when displaying, and even then difficult to hear. Male: an ascending, froglike, rattling pulse of clicks. Also various grunting sounds. Alarm call a harsh "Kraaa".

Appearance:

Very small gull with rounded wings and almost tern-like appearance. Underwing black, with broad white trailing edge. Lacks Black-headed Gull's conspicuous white outer primaries. Adult summer plumage with black (not chocolate) hood, that reaches far down on hind-neck. Winter plumage without hood, but with dark cheek-patch and dark cap. Juveniles differs from juvenile Kittiwake in slender body, dark cap, dark patch at trailing base of underwing, faint dark wing-bar and shorter wings. Can, with experience, be identified by fluttering, butterfly-like flight at long distance.

Sound:

Repertoire of short, tern-like, hard calls, uttered individually, or in series. E.g. "kep" or "krrk". Also a diagnostic, gull-like, sharp and bouncing "ka-tee,ka-tee,ka-tee", with second syllable rising in pitch.
