Appearance:

Medium sized dabbling duck. Noticeably big and wide bill, giving the whole bird a front-heavy look. Male with dark green head, rusty brown flanks and belly. Vent and lower back black, flight feathers dark. Female brown with dark speckles, but with similar huge bill. Speculum green, lacking white rear edge. In flight the darker belly separates it from female mallards. Conspicuous forewing in flight; grey in females and light blue in males.

Sound:

Male is characteristic and most often heard: A hoarse nasal knocking sound "took took", often staccato or disyllabic. Female similar to Mallard but flatter and more creaking.

Appearance:

Fairly large warbler with long tail, giving the whole bird an elongated look. Tertials, secondaries and coverts with rufous fringes in contrast to greyish brown back. Underparts pale with buff flanks. Outer tail feathers white. Steep forehead and white throat. Males with slate grey head.

Sound:

Variable. Usually recognized by fairly concise phrase, usually with three ascending and descending parts. Often ends with more indistinct mimicry, or subsong. May omit characteristic phrase and sing more cryptic for periods of time, and may be more difficult to identify. Warning call a harsh, drawn "weeet", usually with accented ending, sometimes rising abruptly in pitch.
