Mediterranean Gull (Ichthyaetus melanocephalus)
Great Black-backed Gull (Larus marinus)
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.
