About These Birds
Olrog's Gull
Olrog's Gull, 55–58 cm, is an Endangered South American gull breeding in small colonies in Buenos Aires Province, Argentina. Very similar to Belcher's Gull. Piscivore; entirely dependent on mudflats and estuaries of the Buenos Aires coast. Threatened by industrial development of breeding and foraging sites.
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.
