About These Birds
Brown-headed Gull
Brown-headed Gull, 41–46 cm, breeds at high-altitude Tibetan lakes and Central Asian wetlands, wintering on coasts from India to Southeast Asia. Brown hood in breeding plumage; white wing mirrors. Piscivore and invertivore; follows fishing activity in coastal bays.
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.
