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:

Smaller and more delicate than Crane. Front of neck and chest black, with long plumes. Immatures show only faint black markings on neck and head. Upper wing lacks pale patch close to alula, and show little contrast between secondary and primary coverts. Easily mistaken for Crane in flight if black chest is not visible. Identification by call then helpful. Wing beats significantly faster than in Crane.

Sound:

Recalls Crane but timbre very dry, almost rasping and pitch higher.
