Black Kite (Milvus migrans)
Red-billed Chough (Pyrrhocorax pyrrhocorax)
Medium sized, brown raptor with shallowly forked tail. Juveniles with mottled appearance, due to buffed tips of wing coverts. Easily mistaken for Red Kite, but tail is not that deeply forked, upper side of tail is dark brown and head not so pale (plumage colours overall more uniform). Base of primaries paler than the rest of the underwing (especially in Middle-East birds), but with much less contrast to the black wing tips than in Red Kite. Differs from dark morphed Booted Eagle by the forked tail. Wings held horizontally (separates it from harriers). Typically twists it's tail frequently to maintain position in the air (like Red Kite).
Sound:A piercing, first ascending then descending long "piuuu". Starting as a clear tone then gradually taking on a vibrating character that differs from Red Kite. Also a sharp "kieee -ki- ki-ki". More vocal than Red Kite.

CCAll black plumage, red legs and long, curved, red bill. Bill of juveniles yellowish-brown and shorter. Though never as pure yellow as in Alpine Chough, and more curved. Easily confused with Alpine Chough at a distance where both species occur, but note broader, more fingered wings, shorter and squarer tail with broader base and different calls. Flight extremely acrobatic.
Sound:Call: A rapidly descending "keeaaaw", sometimes resembling a coarse jackdaw. At other times a more mewing sound, with similar coarseness, or a sharper, descending "kieew". Easily distinguished from the thin, trilling, whistling sounds of Alpine Chough.
