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.
Antarctic Tern
Antarctic Tern, 31–38 cm, breeds on sub-Antarctic islands and Antarctic Peninsula, dispersing across the Southern Ocean in austral winter. Grey above, white below, with red bill and feet. Unlike Arctic Tern, does not undertake pole-to-pole migration; remains in high southern latitudes year-round.
