Common Scoter (Melanitta nigra)
Great Bustard (Otis tarda)
Medium sized diving duck. Male all black except orange spot on bill. Female dark brown with contrasting light grey cheeks. Differs from Velvet Scoter in all plumages by lack of white wing-bars, and longer tail. Birds resting on the surface characteristically bow their head when occasionally flapping the wings. Wings held tight against body when diving. Last two characters usable for identification at very long range. Also tend to stay closer together in groups than Velvet Scoter.
Sound:More vocal than other Scoters. Short, whistling sounds, sometimes reminiscent of a male teal, but a little bit deeper in pitch.

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.
