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.
