Appearance:

Small dabbling duck. Males unmistakable with broad white supercilium and high contrast between the dark mottled breast and the lighter flanks (visible at considerable distance). Female mottled in light brown colours with typical supercilium and contrasting eye-stripe. White spot at base of bill. Throat much lighter than in Teal. Both sexes with dark and fairly long bill. Head gives a square impression due to the flat crown. Speculum in flight shows narrow white edges, lacking Teal's broad front edge. Agile flight, but lacks the twists of Teals.

Sound:

Male display sound a characteristic dry rattling, like the sound of running fingernails along the teeth of a comb. A bit similar to Ptarmigan. Also heard at other times than when courting. Female: like female Teal, but typically a bit deeper and shorter calls.
