Birds of Namibia
Introduction: Great-winged petrels (Pterodroma macroptera) prefer the warmer, oceanic water of the open ocean and are observed inshore in times of onshore winds. Rests on the water in calm weather, flies singly, in pairs or in small groups of up to 10.
Diet: Attracted to fishing vessels with a more moderate seabird attendance. The most common seabird at trawlers off the southern Namibian coast in summer. Feeds mainly at night by surface-seizing or dipping for squid, crustaceans, carrion and fish. Is associated with dolphins and toothed whales.
Description Fairly large, blackish-brown coloured petrel with a short, stubby bill, long and slender wings. Macroptera is Greek for 'long-winged' and Pterodroma for 'winged runner' referring to their rapid flight.
