About These Birds
Fork-tailed Storm-petrel
Fork-tailed Storm-petrel, 20–23 cm, is a distinctive pale grey storm-petrel of the North Pacific, breeding on islands from California to Japan. Pale blue-grey body, dark wing tips, forked tail. Unlike most storm-petrels, feeds largely on fish and marine debris rather than zooplankton alone. Winters offshore.
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.
