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:

Slightly smaller than Eider. Male at close range unmistakable. At a distance the black back is diagnostic. Female similar to female Eider, but feathering on bill is not reaching nostrils, giving the bird a peculiar "smile". Head shape is less triangular with a steeper forehead, and nail of bill is black. V-shaped barring on flanks.

Sound:

Male: Calls similar to Eider but easily distinguished by the vibrating quality. A "aaaooooooh" (shorter in duration than Eider) Starting on a low note, slowly ascending and ending on a descending note with a distinct vibrato/pulse. Often in the form of three calls: "oohh, a-ohhh hahahaoohohohoh". Usually accompanied by the female "ga ga ga ga".
