Red-necked Nightjar (Caprimulgus ruficollis)
White-tailed Eagle (Haliaeetus albicilla)
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 ".
