Yellow feet (unique among large western gulls), yellow bill with red spot. Piscivore and scavenger; forages on rocky shores. Resident; does not undertake long migrations.
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.
