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.
Aleutian Tern
Aleutian Tern, 32–34 cm, breeds colonially in Alaska and Russian Far East, wintering in Southeast Asian waters — one of the most poorly tracked migrations among seabirds. Dark grey above, white below, black cap with white forehead. Piscivore; dives for small fish. Near Threatened.
