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:

Small, compact diving duck with short neck and rounded head. Males with diagnostic tuft, white flanks and black back. Females with rudimentary tuft, mostly dark brown body, with varying white feathering at base of bill. Females in winter showing much white at base of bill are easily mistaken for Scaup, but note hint of small tuft, smaller head, broad black nail of bill and no white cheek spots. Both sexes show long, white wing stripes in flight.

Sound:

Male display sound: High pitched short whistling-like noises, "pjuu-uu", not very audible. Both sexes have harsh "ahrrrr" calls like other diving ducks, sometimes with a crow-like quality.

Female:
