About These Birds
Hartlaub's Gull
Hartlaub's Gull, 38–40 cm, is endemic to the Benguela Current coast of Namibia and South Africa. White with grey mantle, dark red bill. Resident; forages on beaches, at harbours, and over cold upwelling waters for fish offal and marine invertebrates. Population stable but range restricted.
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.
