Black Kite (Milvus migrans)
Willow Ptarmigan (Lagopus lagopus)
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.

CCSlightly bigger and more heavy build than Ptarmigan, with clearly heavier bill. Summer plumage warm brown above with white belly, showing a warmer brown than Ptarmigan. Winter plumage all white in both sexes, except for black tail. Males lacking black lores. Wings always white in all plumages in nominate ssp. lagopus, and brown in ssp. scotica.
Sound:Very characteristic calls: "Kuwa -Kuwa -Kuwa" (go back!) Also: "kauw kauwkkkrrrkekekekekeke" with a short pause after first "kauw", then a decelerating cackle, often followed by the "go back" call.
