Appearance:

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.
