Appearance:

Unmistakeable in all of WP except for Egypt where Senegal Thick-knee occurs. Differs from said species by more yellow on bill and only narrow white band on coverts framed in black (less prominent in immatures). Mostly nocturnal and easily overlooked at daytime when resting. Runs for cover with hunched posture if disturbed. Easily identified in flight by dark wing with white window, long tail and trailing toes. Betrays it's presence at dusk when groups of birds often starts calling and moving about.

Sound:

Very vocal at twilight with various wailing, curlew-like calls, undulating in crescendoes, often in joined choruses. Most typical call a cyclic "turrru-leeek", with rolling "r" and second part higher pitched (at end of sound file).

Appearance:

Slender and elegant bird, about the same size as Grey Heron. Bill dark in breeding birds, otherwise yellow. Legs and feet dark, but tibia often with red tinge in breeding season. Long, S-shaped neck with sharp angle/bend. Erect posture, and less skulking, horizontal hunting behaviour than Little Egret. Almost twice the size of Little Egret, and wing-beats are considerably slower. Wings give the impression of being attached more upfront than in Little E. Feets protrude well beyond tail in flight.

Sound:

Silent outside breeding ground. In colonies various harsh calls like a dry, and mechanical "kerrrrrrr", and a very nasal "geet" or "ga-geet ga-geet" are heard.
