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.
Western Gull
Western Gull, 55–68 cm, is the dominant large gull on the US Pacific coast from Washington to Baja California. Dark-mantled with pink legs, yellow bill with red spot. Omnivore; breeds on offshore islands, scavenges at harbours and landfills. Non-migratory; resident along its breeding coast.
