About These Birds
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.
Wedge-rumped Storm-petrel
Wedge-rumped Storm-petrel, 19–21 cm, breeds in enormous colonies in the Galápagos and on islands off Peru. The largest white rump patch of any storm-petrel — nearly triangular, extending to the uppertail coverts. Unlike most storm-petrels, daytime activity at colonies. Planktivore in eastern Pacific upwelling.
