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.
