About These Birds
Swallow-tailed Gull
Swallow-tailed Gull, 55–60 cm, is the world's only fully nocturnal gull, breeding on the Galápagos Islands and roosting on the Humboldt Current. Distinctive red orbital ring, black-and-white head, deeply forked tail. Feeds at sea at night on squid and fish attracted to surface by bioluminescence.
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.
