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.
South American Tern
South American Tern, 40–44 cm, is the largest South American tern, breeding from Peru around Cape Horn to southeastern Brazil. Red bill, grey mantle, black cap. Pelagic and coastal piscivore; strong plunge-diver. Movements poorly known; some populations may migrate north along both coasts.
