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.
Mediterranean Gull
Mediterranean Gull, 36–38 cm, has expanded dramatically since the 1970s, breeding across Europe from the Black Sea to Britain. Pure white body, jet-black hood in breeding plumage — the only gull with entirely white wingtips. Piscivore and invertivore; nests in colonies, often with Black-headed Gulls.
