About These Birds
Australian Gull-billed Tern
Australian Gull-billed Tern, 38–42 cm, is a large, heavy-billed tern endemic to Australia, breeding in arid inland wetlands. Pale grey above, white below, with a robust black bill. Takes insects, small reptiles, and crabs rather than diving for fish. Nomadic in response to inland rainfall.
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.
