About These Birds
Silver Gull
Silver Gull, 36–44 cm, is Australia's most familiar gull, present year-round on all coasts and increasingly inland. White body, grey mantle, red bill and legs. Opportunistic omnivore; thrives on human food waste and follows fishing boats. Expanding range inland as irrigation provides new habitat.
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.
