Black-necked Grebe (Podiceps nigricollis)
Great Bustard (Otis tarda)
Small and dark grebe, with squarish head and thin, uptilted bill. Adult breeding plumage distinct, with unique combination of black head and neck, and a spray of golden, fan-like feathers from eye to nape. Winter plumage birds are easily confused with Slavonian Grebe, but note dark, rear cheek-patch, and darker collar. Head profile distinct, with its steep forehead. In winter plumage highest point is above the eye, as opposed to nape in Slavonian. Much more contrasting plumage than Little Grebe. Avoids to take wing if possible.
Sound:Territorial song a disyllabic, flute-like "zoeeee-chk". First part drawn, ascending and plaintive, second part descending and clipping. Timbre is unpure. Other calls include chittering and trilling calls resembling Slavonian or Little Grebe.

CCHeaviest 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.
