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.
Andean Gull
Andean Gull, 45–48 cm, breeds at high-altitude Andean lakes from Colombia to Argentina, typically above 3000 m. Black hood in breeding plumage; white below with grey mantle. Largely insectivore, following cattle or foraging at lake edges. Partial altitudinal migrant descending to Pacific and Atlantic coasts in winter.
