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.
Aleutian Tern
Aleutian Tern, 32–34 cm, breeds colonially in Alaska and Russian Far East, wintering in Southeast Asian waters — one of the most poorly tracked migrations among seabirds. Dark grey above, white below, black cap with white forehead. Piscivore; dives for small fish. Near Threatened.
