About These Birds
Black-tailed Gull
Black-tailed Gull, 44–48 cm, is common on East Asian coasts from Russia to China, Japan, and Korea. Grey mantle, white body, yellow bill with red spot and black subterminal band, yellow legs. Omnivore; very vocal, known as the 'cat gull' for its mewing calls. Migratory; winters south to Vietnam.
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.
