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).
