About These Birds
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.
Aleutian Tern
Aleutian Tern, 32–34 cm, breeds colonially in Alaska and Russian Far East, wintering in Southeast Asian waters — one of the most poorly tracked migrations among seabirds. Dark grey above, white below, black cap with white forehead. Piscivore; dives for small fish. Near Threatened.
