About These Birds
Glaucous-winged Gull
Glaucous-winged Gull, 56–68 cm, is the common large gull of the North Pacific from Alaska to California. Distinctive pale grey wing tips (not black) give a uniform grey appearance. Omnivore; forages on rocky shores and at harbours. Hybridises with Western, Herring, and Glaucous Gulls.
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.
