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.
Greater Crested Tern
Greater Crested Tern, 43–48 cm, is the largest crested tern of the Indo-Pacific, breeding from South Africa to Japan and Australia. Yellow-green bill, prominent black crest, grey back. Colonial breeder on sand islands; plunge-dives for fish. Partially migratory; disperses across Indian and Pacific Oceans.
