Appearance:

A medium sized, long-winged raptor, with deeply forked tail. Adults with warm brown underparts and typical whitish "window" contrasting with black wing tips. Tail rufous above. Easily confused with Black Kite, but this has shallower forked tail and gives a darker brown impression. Note that birds gliding with tail fanned may give impression of less forked tail. Flight elegant, with frequent and typical tail twisting to maintain position in the air.

Sound:

Mainly heard in breeding season. A piercing long whistle, quickly ascending, then descending "piuuu". Often used in movies to give an eerie wildlife mood. Differs from Black Kite in being a clear whistle all the way through the call, without "shivering". Higher pitched than Buzzard, and with less pause between calls.

Appearance:

Very small gull with rounded wings and almost tern-like appearance. Underwing black, with broad white trailing edge. Lacks Black-headed Gull's conspicuous white outer primaries. Adult summer plumage with black (not chocolate) hood, that reaches far down on hind-neck. Winter plumage without hood, but with dark cheek-patch and dark cap. Juveniles differs from juvenile Kittiwake in slender body, dark cap, dark patch at trailing base of underwing, faint dark wing-bar and shorter wings. Can, with experience, be identified by fluttering, butterfly-like flight at long distance.

Sound:

Repertoire of short, tern-like, hard calls, uttered individually, or in series. E.g. "kep" or "krrk". Also a diagnostic, gull-like, sharp and bouncing "ka-tee,ka-tee,ka-tee", with second syllable rising in pitch.
