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.
Bridled Tern
Bridled Tern, 30–32 cm, breeds on tropical islands across the Indo-Pacific and Atlantic. Dark brownish-black above with a white forehead stripe extending behind the eye — the diagnostic 'bridle'. Pelagic outside breeding; piscivore, takes fish and squid at the surface.
