About These Birds
Atlantic White Tern
Atlantic White Tern: 28–33 cm, wingspan 76–87 cm, ethereally white seabird with blue-grey bill, blue orbital ring, and large dark eyes. Breeds on tropical Atlantic islands including Ascension and Saint Helena; related species widespread across the Indo-Pacific. Nests on bare branches with no nest material. Feeds on small fish near the surface.
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.
