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.
