Collared Pratincole (Glareola pratincola)
River Warbler (Locustella fluviatilis)
Slightly smaller than Golden Plover with much slender appearance. Only likely to be confused with other pratincoles, but diagnostic field marks often difficult to see. Differs from Black-winged Pratincole by rufous underwing and narrow, white trailing edge to upperwing (both characters requires good light). Tail streamers longer than wing-tips and base of bill with more red (in breeding plumage). Sexes alike. Lacks black necklace in winter plumage. Immature birds are similar to winter-plumaged adults, but with additional scaly upperparts. Often confusing at first glance when in flight, due to tern-like, acrobatic flight not resembling other waders.
Sound:Quite vocal. Nasal tern-like, far-carrying calls often betrays its presence before it is seen. Short and sharp "kiev" or "kip" frequently used. Most diagnostic call is a two-part, rolling "kivik-kirrrrrrr", with the latter part slightly descending. Easily confused with Black-winged Pratincole, but the hard parts are more resonant, and less clicking and staccato, while the more melodic components are less mewing. Also quite similar to Little Tern in timbre, but the two-part structure in the diagnostic call is different.

CCA long-tailed and relatively long-winged Locustella, with olive-brown plumage and pale belly. Conspicuously broad, rounded tail, and substantial vent. Under tail coverts brown with with prominent pale fringes, and almost reaches tail tip. Faintly streaked throat and breast. Rump and tail warmer brown than back. Faint and short supercilium and pale eye-ring. First long primary with pale outer web, and a slight curve. Song-posts often more exposed than Grasshopper Warbler.
Sound:Song an insectlike, buzzing like Grasshopper and Savi's Warbler, but easily distinguished from those by it's distinct steam locomotive-like rhythm. About 8 accents per second. Perhaps easier to confuse with certain species of ground crickets or cicadas than it's congeners. Contact call a sharp "tsikk-tsikk", similar to Savi's Warbler.
