About These Birds
Black-billed Gull
Black-billed Gull, 35–38 cm, is endemic to New Zealand, breeding on South Island braided riverbeds. All-white plumage with a slender black bill and black-tipped wings. Endangered; river modification and mammal predation depress breeding success. Insectivore and piscivore in river and coastal habitats.
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.
