Taxonomic note
Pterodroma macroptera and P. gouldi (del Hoyo and Collar 2014) were previously lumped as P. macroptera following Sibley and Monroe (1990, 1993).

Distribution and population
The Great-winged Petrel breeds in the Southern Hemisphere between 30 and 50 degrees south with colonies on Tristan da Cunha and Gough Island (St Helena to UK), the Crozet Islands and Kerguelen Islands (French Southern Territories) the Prince Edward Islands (South Africa), and on the coasts of southern Australia and northern New Zealand. Outside the breeding season it dispereses widely in subtropical parts of the Atlantic, Indian and Pacific Oceans, mainly between 25 and 50 degrees south, though some birds will stray into the Antarctic zone (del Hoyo et al. 1992).

Ecology
This marine species is highly pelagic and has a widespread but sparse distribution at sea. It feeds mostly on squid, with some fish and crustaceans, most of which it obtains by dipping and surface-seizing. It feeds mainly at night and may locate some cephalopods by their bioluminescence. It can occasionally be seen following cetaceans and will associate with other Procellariiformes. Breeding occurs in winter, starting in April, nesting being either solitary or in small colonies on oceanic islands on ridges, slopes or flat ground. Breeding usually occurs below 400 m, but has been recorded as high as 1400 m on Tristan de Cunha. It nests in burrows or above ground in rock crevices, among tree roots or under scrub (del Hoyo et al. 1992).
