Appearance:

Olive green upperparts, yellowish chest with gradual transition to off-white belly. Very similar to Willow Warbler, and most field characters are subtle and often hard to see. Distinguished by (usually) black, or dark-brown legs, only faint dark framing to ear-coverts, less marked supercilium. Shorter primary projection (1/2 to 2/3'rds the lenght of tertials), with regularly spaced tips (visible when wing folded). Wings more fan-shaped and less pointed than in Willow Warbler. Juveniles much less yellow below than in W.Warbler. Generally leaves a duller and greyer impression than W. Warbler, but plumage very variable. Frequently flicks tail, even sideways. Generally also more active when moving among the foliage.

Sound:

Contact/alarm call a soft, plaintive ascending "hooeet". Similar to W.Warbler, but shorter with a monosyllabic feel. Song a very distinct: "chiff-chaff-chiff-chiff-chaff-chiff", in a regular clock-like rhythm. Each syllable at seemingly random pitch, but no large intervals tonally. Sometimes "get stuck" at one note.

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.
