Appearance:

May be confused with Ruddy Shelduck, but differs in long, pinkish legs, pink bill, long neck, greyish underparts and striking, brown mask. Conspicuous black and white wing pattern similar to Ruddy Shelduck, but crossed with a thin, black stripe. Sexes similar. Immature duller and without facial mask, and thus closer to RS in appearance. Spends much time foraging while walking, but may also dive. Flight heavy and goose-like.

Sound:

Quite vocal when interacting. Female calls may resemble RS, but are coarser, harder and trills are more rolling. Single calls are longer, and falls markedly in pitch. Male calls quite different, with husky, wheezing or hissing "kaahhh", or with the same timbre in series lika a steam engine.

Appearance:

Unmistakable in summer with almost all black plumage. White oval wing-patches in all plumages. Only auk with white wing-panels. Bill quite slender and pointed, body and wings rounded. Winter plumage blotched in grey and white, with dark wings (with white coverts). Typically scans for food by frequently dipping forehead in the water.

Sound:

Call surprisingly high pitched. Quite pure, drawn out, plaintive whistling notes in same pitch range as Hazel Grouse.
