Stone Curlew (Burhinus oedicnemus)
River Warbler (Locustella fluviatilis)
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).

CCA long-tailed and relatively long-winged Locustella, with olive-brown plumage and pale belly. Conspicuously broad, rounded tail, and substantial vent. Under tail coverts brown with with prominent pale fringes, and almost reaches tail tip. Faintly streaked throat and breast. Rump and tail warmer brown than back. Faint and short supercilium and pale eye-ring. First long primary with pale outer web, and a slight curve. Song-posts often more exposed than Grasshopper Warbler.
Sound:Song an insectlike, buzzing like Grasshopper and Savi's Warbler, but easily distinguished from those by it's distinct steam locomotive-like rhythm. About 8 accents per second. Perhaps easier to confuse with certain species of ground crickets or cicadas than it's congeners. Contact call a sharp "tsikk-tsikk", similar to Savi's Warbler.
