About These Birds
Mediterranean Gull
Mediterranean Gull, 36–38 cm, has expanded dramatically since the 1970s, breeding across Europe from the Black Sea to Britain. Pure white body, jet-black hood in breeding plumage — the only gull with entirely white wingtips. Piscivore and invertivore; nests in colonies, often with Black-headed Gulls.
Slaty-backed Gull
Slaty-backed Gull, 55–68 cm, breeds on coasts and cliffs of the Russian Far East, wintering south to Japan and occasionally the US Pacific coast. Dark slate-grey mantle, pink legs, 'string of pearls' white mirrors on outer wing. Omnivore; scavenges at fishing ports in East Asian harbours.
