Appearance:

May only be confused with Egyptian Goose, but differs in short, dark legs, dark bill, thicker neck, rufous belly and lack of eye-patch. Black and white wings conspicuous in flight as in Egyptian Goose, but lacks thin, black stripe at rear of white coverts. Sexes quite similar. Male with ringed neck in breeding plumage, and female with more contrasting facial pattern. Immature similar to female, but with "dirty" white wing-patches. Less dependent on water than most other ducks.

Sound:

Distinct voice and quite vocal. Nasal, trumpeting, donkey-like calls, often drawn out to a rattling, trill (Chewbacca of Star Wars). Male higher pitched than female.
