Appearance:

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.

Appearance:

Small eagle with evenly broad wings and relatively short tail. Easily confused with Greater Spotted Eagle (C. clanga). Flight-feathers darker than the pale brown coverts, both on upper- and underwing. Head and body distinctly paler than flight feathers. Conspicuous pale patch at base of inner primaries on upperwing (diffuse only in C. clanga). Double "commas" on underwing, formed by pale base of primaries and primary-coverts (one "comma" in C. clanga). Wings more narrow than C. clanga, which makes the tail look slightly longer. U-shaped white patch at base of tail. Immature birds with white tipped greater and median coverts, forming two narrow wing-bands. Wings "fingered", but 7th finger shorter than in C. clanga (but varies with age). Sours and glides with wings held horizontally, but with characteristic drooping hand (similar to C. clanga).

Sound:

Vocal at breeding ground, and when courting. Short, barking, high-pitched whistles, not unlike a small dog. Slightly higher pitched than C. clanga and with a purer tone, but very similar.
