About These Birds

Ringed Storm-petrel

Ringed Storm-petrel, 21–23 cm, is an extremely poorly known species with a highly restricted range over the Humboldt Current off Peru and Chile. White underparts with a distinctive dark breast band — giving the 'ringed' appearance. Breeding grounds unknown until recently; likely nests in Atacama Desert.

European Storm-petrel

European Storm-petrel, 14–18 cm, wingspan 36–39 cm, is the smallest seabird in European waters, breeding in burrows and rock crevices on Atlantic islands from Iceland to the Mediterranean. Entirely sooty black with white rump. Strictly nocturnal at colonies. Planktivore; patters over wave surface picking up oil and plankton.
