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.
Andean Gull
Andean Gull, 45–48 cm, breeds at high-altitude Andean lakes from Colombia to Argentina, typically above 3000 m. Black hood in breeding plumage; white below with grey mantle. Largely insectivore, following cattle or foraging at lake edges. Partial altitudinal migrant descending to Pacific and Atlantic coasts in winter.
