About These Birds
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.
Roseate Tern
Roseate Tern, 33–36 cm, is a globally distributed but declining species, breeding on both sides of the Atlantic, Indian Ocean, and Pacific. Nearly white with a rosy flush to breast in spring, very long tail streamers, and mostly black bill. Plunge-dives for small fish. Endangered in parts of range.
