About These Birds
Heermann's Gull
Heermann's Gull, 46–51 cm, is distinctive — dark grey body, white head (breeding), red bill. Breeds almost entirely on Isla Rasa in the Gulf of California, then disperses north along the Pacific coast to British Columbia. Kleptoparasite; steals fish from Brown Pelicans. Near Threatened; range highly restricted.
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.
