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.
Grey-backed Tern
Grey-backed Tern, 35–37 cm, is a Pacific seabird breeding on islands from Hawaii to Micronesia and Polynesia. Pale grey back distinguishes it from the similar Bridled Tern; white below with black cap. Piscivore; surface-dips and shallow plunge-dives. Largely pelagic when not breeding.
