Appearance:

Large tern with black bill, with yellow tip (adults). Bill all black in juveniles. Long black cap and shaggy crest. Generally leaves a much whiter impression than other terns in the region (except Roseate Tern). Adult summer: Yellow bill-tip. Tail pure white, and upperparts pale grey. Outer primaries darker than rest of wing, and contrast increases in worn plumage. Broad white trailing edge to inner wing. Underside of primaries with faint narrow dark trailing edge. Forehead white in adult winter and first winter plumage. Juveniles: scaly upperparts and dark bill. Less evenly coloured than juvenile Gull-billed Tern. First winter birds similar to juveniles, but back purer grey and bill shorter. Can be mistaken for Gull-billed Tern, but note different profile. Flight powerful with evenly narrow wings and a front-heavy appearance, due to the long head and bill. Often dives from high above the surface and stays under water longer than Common and Arctic T.

Sound:

Contact call a sharp and grating "keeree-eek". Often compared to the pressing of amalgam into a tooth.

Appearance:

Large, long-winged vulture with slender body and long, diamond-shaped tail. Very different flight-silhouette from any other large raptor in the region. Most similar to Egyptian Vulture (Neophron percnopterus), but note very long tail (longer than wings are broad) and pointed wings. Size difference not always apparent. Adult birds unmistakable when plumage characters are visible. Yellowish head with black mask and "beard". Orangy underparts, contrasting with dark back, wings and tail. Immature birds are dark all over, with pale-tipped coverts. Note that young birds have shorter tail and less pointed wings than adults. Wings held flat when soaring, sometimes with tip pointing slightly downwards.

Sound:

Display call a thin whistling with several register breaks, reminiscent of Honey Buzzard (Pernis apivorus). A passerine-like trill is also sometimes heard, but generally not a vocal bird.
