About These Birds
Black-tailed Gull
Black-tailed Gull, 44–48 cm, is common on East Asian coasts from Russia to China, Japan, and Korea. Grey mantle, white body, yellow bill with red spot and black subterminal band, yellow legs. Omnivore; very vocal, known as the 'cat gull' for its mewing calls. Migratory; winters south to Vietnam.
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.
