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.
Snowy-crowned Tern
Snowy-crowned Tern, 33–35 cm, breeds along the Atlantic coasts of Argentina and Uruguay, wintering north to southern Brazil. White crown with black post-ocular mark (unlike a full black cap), yellow-tipped red bill. Coastal and estuarine piscivore; plunge-dives for small fish.
