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:

Similar to Reed Warbler but note very short primary projection, evenly coloured wings with dull tertials. Under tail-coverts almost white, with very little buff tinge. Legs overall darker than congeners. Immature birds with slightly paler legs and warmer upperparts and fringes to flight-feathers. Leaves a slimmer impression than Reed- and Marsh W., with flatter forehead and tapering bill. Posture often Sylvia-like with frequent cocking, flicking and fanning of tail.

Sound:

Contact call a short and sharp Lesser Whitethroat-like "tek", different from Mars W. Alarm call a dry, rolling "krrrreet", often with a register break splitting into high register overtones. Song recalls Marsh Warbler in timbre but is generally diagnostic. Tempo slow and deliberate, pace recalling that of Song Thrush, with marked pauses. Typical articulate, arpeggio-like whistling motifs alternated by mimicry are often repeated many times. Daytime song less typical than normal song at night, with faster pace and less repetition.
