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:

Most likely to be confused with Black-tailed Godwit, but easily recognized in flight by plain dark wings, white wedge on back and barred tail. More difficult to identify when not flying. Generally more compact, heavier built and less upright than Black-tailed, and with clearly upcurved bill and shorter legs. Belly always unmarked. Base of bill dark in summer and pinkish in winter and in juveniles. Back with arrow-shaped streaking. Adult winter also streaked, and the pale supercilium reaches behind the eye.

Sound:

Quite vocal at breeding ground but mostly silent elsewhere. Varied repertoire of mewing and sharp sounds, some resembling Black-tailed, some almost Snipe-like. Contact call a sharp "kwee-kee-wee-kee", with alternating high and low pitch, and decreasing intensity. Display call a hard and sharp "kuwek-kuwek-kuwek-kuwek", with emphasis on second syllable.
