Appearance:

Easily confused with Whooper Swan, but yellow on bill restricted to a rounded patch. May sometimes extend towards the bill-tip, but never beyond nostrils. Angle of mouth bold black. Gives a more compact impression than Whooper, due to shorter neck. Head shape noticeably more rounded, and seemingly larger. Juveniles paler grey than Whooper, with the same bill pattern as in adults, but in faint, pale yellow and pink. Flight easy and goose-like.

Sound:

More vocal than other swans. Both higher pitched and deeper sounds. Birds on the water often gives crooning, crane-like notes with less defined pitch. Tone is less full-bodied in these calls. Flight call a deep, yelping, soft barking sound. Each call short, with a "helpless" quality.

Small bustard about the seize of female pheasant. Stocky body, small head, slender neck and fairly long legs. Male: Grey head, black neck with two white rings, finely vermiculated upperparts and white underparts. Odd short p7 in male. Female lacks black neck and all upperparts are a vermiculated sandy brown. Young and non-breeding males similar to females, but often with a hint of white breast-band and more clearly defined white underparts. Told from Great Bustard in flight by clear cut black wing-tips and primary coverts in sharp contrast to white wing, and white secondaries. Flushed birds take off in noisy, grouse-like manner with rapid wing-beats and interspersed short glides on bowed wings. Longer flight with quick wing-beats mostly below level of back.

Sound:

Wings in male produces a whistling sound when flying and in display flight. Flushed birds give a hoarse grunt "ugh". Female sometimes utters e mewing "miee". Male song a short and dry "prrrt", that is far reaching. Given from ground in display in 5 - 10 seconds intervals with raised neck-feathers and jumps in the air.
