Arctic Warbler (Phylloscopus borealis)
Black Kite (Milvus migrans)
Like a large Willow Warbler, with distinct dark eye-stripe. Supercilium marked, but narrow. Starts at base of bill, continuing far behind eye. Wing-bar distinct on greater coverts, and sometimes on median coverts too. Primary projection long. Bill long and relatively heavy with orange base. Flanks often slightly grey, and throat sometimes with faint streaking. Appearance robust, but elegant. Moves faster and with more confidence than congeners.
Sound:Call and song diagnostic. Song a rattling series of 20-30 single syllables. Repeated as a monotonous phrase in stable pitch, lasting 2-4 seconds. Starts more softly with volume rising throughout each phrase. Contact call equally unique. A hard and short "tsrrt", recalling contact call of Dipper. Often given as introductory part of song.

CCMedium 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.
