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".
