Appearance:

Small, but bulky gull. Black hood with white crescents above and below eye, blood-red bill and legs in breeding plumage. The rest of the body seems all white at a distance. Wingtips pure white in adult birds. Chest deeper than in Black-headed gull, and wings fairly broad and rounded. In winter the black hood is largely lost, but dark streaking around, and at the back of the eye remains. Juveniles can be confused with juvenile Mew Gull (Common Gull), but note white under wing-coverts, pale grey band (greater coverts) across secondaries, black or reddish bill and more narrow terminal band of tail. Paler belly than Mew/Common Gull. Second year birds are similar to adult winter, but varying degrees of black markings remains on wing-tips.

Sound:

Distinct calls which can be identified even in mixed flocks. Most common call a short, mewing "yeah". Pitch rises and fall rapidly, with a "surprised" intonation. Timbre is nasal but clear and pure. Alarm call a series of short "ke-ke-ke", with similar timbre.

Appearance:

Small eagle with evenly broad wings and relatively short tail. Easily confused with Greater Spotted Eagle (C. clanga). Flight-feathers darker than the pale brown coverts, both on upper- and underwing. Head and body distinctly paler than flight feathers. Conspicuous pale patch at base of inner primaries on upperwing (diffuse only in C. clanga). Double "commas" on underwing, formed by pale base of primaries and primary-coverts (one "comma" in C. clanga). Wings more narrow than C. clanga, which makes the tail look slightly longer. U-shaped white patch at base of tail. Immature birds with white tipped greater and median coverts, forming two narrow wing-bands. Wings "fingered", but 7th finger shorter than in C. clanga (but varies with age). Sours and glides with wings held horizontally, but with characteristic drooping hand (similar to C. clanga).

Sound:

Vocal at breeding ground, and when courting. Short, barking, high-pitched whistles, not unlike a small dog. Slightly higher pitched than C. clanga and with a purer tone, but very similar.
