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:

Small head, short, thick neck, quite broad wings and fairly short tail. May be confused with a range of different species due to the highly variable plumage. Underparts range from almost white to very dark. Plumage tone ranges from chocolate to rusty brown. Dark morph usually with pale breast band. Shows 5 fingers like other Buteo, as opposed to small eagles. Tail lacks the broad terminal band of Rough-legged Buzzard. Neck thicker than in Honey Buzzard. Secondary coverts form a pale band in dark morph. Light morph typically with primary coverts forming black 'comma'. Soars with raised wings, but glides on straight wings.

Sound:

Quite vocal. Most typical call a wailing, mewing "peeoooo". Quite similar to Rough-legged Buzzard, but the pitch falls more rapidly and is then sustained for the last part of the call.
