Velvet Scoter (Melanitta fusca)
Black-winged Pratincole (Glareola nordmanni)
White secondaries the most striking feature in all plumages. Generally heavy built with large bill, heavy head, thick neck and short tail. Male: black with white crescent below eye and partly orange bill. Female sooty black with variable light patches at lore and cheek. Flaps it's wings with a raised head when on water. Dives without jumping and with wings slightly open. Swimming birds may not always show white secondaries. Tends to form less dense flocks than Common Scoter, often with birds in single file.
Sound:Seldom heard. Calls: Short accented "tup tup tup" and a shivering "gahhahahaha".

CCOnly likely to be confused with other pratincoles, but diagnostic field marks often difficult to see. Differs from Collared Pratincole by black underwing and lack of white trailing edge to upperwing (both characters requires good light). Tail streamers shorter than wing-tips and base of bill with less red (in breeding plumage). Build slightly stockier than Collared Pratincole, with longer legs. Lore and forehead often darker. Sexes alike. Lacks black necklace in winter plumage. Immature birds are similar to winter-plumaged adults, but with additional scaly upperparts. A third species, Oriental Pratincole, is a rare vagrant with rufous underwing, no wing-bar, and even shorter tail.
Sound:Also see Collared Pratincole. Differs from latter by the hard parts being dryer, more clicking and staccato, while the more melodic components are more mewing. Like with Collared Pratincole beware confusion risk with Little Tern, which is similar in timbre.
