About These Birds
Inca Tern
Inca Tern, 39–42 cm, is unmistakable — dark slate grey with white facial plumes curling from the bill like a Victorian moustache. Restricted to the Humboldt Current from Peru to Chile. Piscivore; snatches anchovies and other prey at the surface. Near Threatened; population tied to anchovy availability.
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.
