Appearance:

Unmistakable if seen well. Corvoid-like at a distance, and may be mistaken for Jay if no plumage characters are visible. Tail is however quite a bit shorter, and wings slightly longer. Flight-feathers dark, contrasting with turquois coverts, both below and above. Underparts especially striking in flight, being pale blue (sometimes seemingly white) all over, except dark flight-feathers and base of tail. Bill heavy. Immature duller than adults with faint streaked breast and slightly rufous coverts. Wing-beats deep and regular. Flies mostly in a straight line. Migrating birds move in characteristic procession-like formations.

Sound:

Various dry rasping, sometimes mewing, sounds and short clicks: "ahrahrahrahrahrahrahr" or pulse of clicks: "trrrtrrrrtrr". Also a clearer raptor- or jay-like descending "piiuu".

Appearance:

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.
