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.
Ivory Gull
Ivory Gull, 40–43 cm, is entirely white with black legs, breeding only on High Arctic ice caps and cliffs in Canada, Greenland, Svalbard, and Russia. Winters at sea ice edges in the High Arctic. Scavenges on marine mammal carcasses and sea ice invertebrates. Near Threatened; climate-sensitive.
