Great-winged Petrel

Pterodroma macroptera

Large532 gMarine

This is a large seabird, with a body length of 42–45 cm. The bird is completely dark brown except for a variable patch of white near the base of the bill, which is black. It is separated from sooty shearwater and short-tailed shearwater by the all-dark underwing, the thick, stubby bill, and different jizz. The similar flesh-footed shearwater has a light, pinkish bill. Petrels in the genus Procellaria are larger and have a less bounding flight.
