Stone Curlew (Burhinus oedicnemus)
Sooty Shearwater (Ardenna grisea)
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).
Two types of call:

CCDark-bellied, long-billed shearwater with small head and elongated body. Wings long, narrow and pointed, with pale patches/bands underneath framed in dark base colour of body. Flight fast and powerful. In strong winds hand held pointing slightly backwards. The pale underwing is clearly visible in good light, but the whole bird often seems completely dark. Only shearwater in the region with completely dark underparts, except from dark individuals of the much smaller, and short-winged, Balearic Shearwater. The latter also shows deeper belly and less deep chest. At long distance, and/or bad weather, Sooty Shearwater may be confused with Arctic Skua or even young Gannets. Differs from Gannets by size, shorter neck and no white rump patch. Told from Skuas by bursting series of stiff wing-beats with alternating glides.
Sound:Mostly heard at breeding ground. A peculiar, rhythmic, coarse moaning, with a disyllabic attack, followed by a deeper, cooing "in-breath".
