Appearance:

Big and white waterfowl with orange bill and black knob at base of bill. Juveniles more greyish and differs from juvenile Whoopers by all grey bill and black lores. Neck usually held more S-shaped than other swans when swimming. Long tail prominent when upending.

Sound:

Silent compared to other swans. A repertoire of snorting, grunting and hissing sound when interacting. No far carrying sounds. Wings produce prominent singing sound which may function as a flight contact-call.

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.
