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.
African Skimmer
African Skimmer: 36–42 cm, black-and-white skimmer with a long bright orange-yellow bill where the lower mandible is longer than the upper. Flies low over large rivers and lakes, cutting the water surface with the lower bill to catch fish. Resident and partial migrant along large rivers and lakes of sub-Saharan Africa. NT.
