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.
Lava Gull
Lava Gull, 52–55 cm, is the world's rarest gull — only ~800–1,000 individuals exist, all on the Galápagos Islands. Sooty grey overall, white eyelids, red bill and feet. Scavenges at fishing ports and seal colonies; omnivore. Restricted range makes it highly vulnerable to any environmental change.
