Appearance:

Told from Common Nightjar by evenly broad pale bands on coverts, no dark leading edge of wing and rufous necklace all around nape. Underparts more rufous than C. Nightjar, and white throat-patch larger. Sexes are very similar, and both show white patches on wings and tail. Larger than C.N. and with experience possible to identify in silhouetting flight by it's larger head and longer tail.

Sound:

Female calls with rasping series of "eech-eech-eech-eech". Flightcall resembles C.N. Song very diagnostic, and not likely to be confused with any other sound. May be described as a fairly deep and resonant knocking, with a steam-engine-like rhythm; "ko-tok, ko-tok, ko-tok, ko-tok ".

Appearance:

Small vulture with characteristic flight profile, and distinct plumage with white body, white coverts and black flight feathers (in adults). Long, wedge-shaped tail, but not longer than wings are broad (as opposed to Lammergeier). Wings square with broad, full hand (slightly pointed in Lammergeier). Small head with thin bill. At long distance plumage of adults slightly similar to White Pelican, White Stork and pale Booted Eagles, but note wedge-shaped tail. Immature birds dark brown with paler coverts. Despite the less distinct plumage, the silhouette is similar to adults. Noticeably more active wing flapping and quicker wing-beats than in the large vultures.

Sound:

Almost never heard. May emit different grunting sounds and a slightly mallard-like "ga ga ga ga ga ga ga".
