Mediterranean Gull (Ichthyaetus melanocephalus)
Black-winged Pratincole (Glareola nordmanni)
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.

Only likely to be confused with other pratincoles, but diagnostic field marks often difficult to see. Differs from Collared Pratincole by black underwing and lack of white trailing edge to upperwing (both characters requires good light). Tail streamers shorter than wing-tips and base of bill with less red (in breeding plumage). Build slightly stockier than Collared Pratincole, with longer legs. Lore and forehead often darker. Sexes alike. Lacks black necklace in winter plumage. Immature birds are similar to winter-plumaged adults, but with additional scaly upperparts. A third species, Oriental Pratincole, is a rare vagrant with rufous underwing, no wing-bar, and even shorter tail.
Sound:Also see Collared Pratincole. Differs from latter by the hard parts being dryer, more clicking and staccato, while the more melodic components are more mewing. Like with Collared Pratincole beware confusion risk with Little Tern, which is similar in timbre.
