About These Birds
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.
Kerguelen Tern
Kerguelen Tern, 31–33 cm, is restricted to a handful of sub-Antarctic islands including Kerguelen and Crozet. Darker grey than Antarctic Tern, with reddish bill. Piscivore and invertivore; forages in kelp beds and coastal waters. Near Threatened; small, isolated population vulnerable to introduced predators.
