Little Bustard (Tetrax tetrax)
Great Bustard (Otis tarda)
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.

Heaviest bird in area. Stocky with well developed chest. Male 50% larger than female. Mostly unmistakable, and differs from all other bustards in area in all plumages by pale, grey head (yellowish grey in female), clearly paler than the rufous upperparts and lower neck. Male with thick neck, rufous chest and long moustache feathers. Female with more slender neck and duller colours. In flight the big white wing-patch is conspicuous. Base of hand pale with smooth transition to dark tips. Secondaries black. When displaying the male raises wings and body feathers to a "foam-bath" posture with head held low, like a white ball of feathers. Flight heavy but majestic. Shy and alert bird.
Sound:Mostly silent, especially away from breeding ground. Display call a short deep, hollow thud "omp", using resonating gular pouch. Most heard is a nasal grunt used in various types of excitement. Sometimes given in a flatulent series.
