Near Threatened; range highly restricted.
Vega Gull
Vega Gull, 55–68 cm, breeds in Siberia and winters on Pacific coasts from Japan to China. Formerly considered a subspecies of Herring Gull; slightly darker grey mantle, pink-fleshed orbital ring. Omnivore; scavenges at ports and forages along rocky coasts. Migratory; common in East Asian harbours in winter.
