Appearance:

Very large tern, with deep, dagger-like, blood-red bill with dark tip. Large, black cap reaching well below the eyes. Grey upperparts and white underparts. Rather short tail. Outer primaries distinctly darker than the rest of upperwing, and outer underwing almost black. Unmistakable from the size alone, and leaves a gull-like impression, lacking the elegance of smaller terns. Immatures with paler bill and white forehead (as in adult winter), and markedly speckled back. Hovers and dives. Often rests on the surface, feeding like a gull.

Sound:

Easily recognized by its very harsh calls. Sometimes likened to the sound of a plate of steel being dragged across a concrete floor. Similar in harshness to Grey Heron, but more drawn, with an accented middle; "Kraaeeet", or with a double syllable start "ka-ha-kraaaeet". Immature birds begs with a penetrating, sharp whistle.

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.
