Appearance:

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.

Appearance:

Summer plumage unmistakable, with black underparts framed in white, with white and grey-speckled upperparts. Diagnostic in all plumages are the black armpits, which are clearly visible in flying birds. Also shows white wing-bars and very pale tail, with some barring. Winter-plumaged and juvenile birds speckled in grey with white underparts. Can be mistaken for Golden Plover. Especially the juveniles, which may have faint golden tone to plumage. Note instead heavier bill with swollen tip and bulkier body.

Sound:

Contact call diagnostic. A plaintive, drawn and trisyllabic (but continuous) "kleeooowee". Pitch falls on second syllable and rises on last.
