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.
Forster's Tern
Forster's Tern, 33–36 cm, breeds in interior North American marshes and winters along both US coasts and into Mexico. Distinctive frosted silver upperparts and orange-based bill. In non-breeding plumage, shows a black eye-mask. Piscivore; hovers and plunge-dives in coastal bays and lagoons.
