Appearance:

Very similar to Common Swift, and often difficult to identify in the field. Seeing the birds against a darker background, as opposed to the sky, brings out some of the characters more clearly. Generally paler and more sandy brown than Common Swift. Differs further from C. Swift by: Rounder wing tip (outermost primary shorter than the next), slightly broader wings, broader and flatter head. White throat patch bigger and more prominent. The face seems paler, which brings out the dark eye-mask. Back slightly darker than upper part of wings. More contrast between outer and inner primaries. Underparts with more pronounced scaly pattern. Flight less acrobatic, with slightly slower wing-beats, more frequent gliding and much less twinkling turns.

Sound:

Similar to Common Swift, but usually very helpful for ID. Almost di-syllabic, with marked accent on second syllable which rapidly drops in pitch, "srrrree-aah". Common swift has a more even call, with accents on first part, without the sudden pitch-drop.

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.
