Black-winged Pratincole (Glareola nordmanni)
Black Grouse (Lyrurus tetrix)
Only 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.

Male differs from Capercaillie in smaller size, stockier build, curled outer tail-feathers and pure white under tail-coverts. Both sexes with white wing bars. Female more evenly speckled than Capercaillie, lacking brick coloured patches on breast an neck. Much less noisy when flushed than Capercaillie.
Sound:Song: a far reaching, continuous, bubbly cooing, occasionally interrupted by a hissing "chooo-eee". Female calls with a nasal "go-go-go-gooo", ending on a falling drawn-out note.
