Blyth's Reed Warbler (Acrocephalus dumetorum)
Black Kite (Milvus migrans)
Similar to Reed Warbler but note very short primary projection, evenly coloured wings with dull tertials. Under tail-coverts almost white, with very little buff tinge. Legs overall darker than congeners. Immature birds with slightly paler legs and warmer upperparts and fringes to flight-feathers. Leaves a slimmer impression than Reed- and Marsh W., with flatter forehead and tapering bill. Posture often Sylvia-like with frequent cocking, flicking and fanning of tail.
Sound:Contact call a short and sharp Lesser Whitethroat-like "tek", different from Mars W. Alarm call a dry, rolling "krrrreet", often with a register break splitting into high register overtones. Song recalls Marsh Warbler in timbre but is generally diagnostic. Tempo slow and deliberate, pace recalling that of Song Thrush, with marked pauses. Typical articulate, arpeggio-like whistling motifs alternated by mimicry are often repeated many times. Daytime song less typical than normal song at night, with faster pace and less repetition.

CCSound recording:Recorded by Edmunds Racinskis
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.
