The Great-winged petrel is an all dark-brown gadfly petrel found in the 'Roaring Forties.' They breed in winter and lay a single egg in May to July in burrows excavated out of vegetated peat slopes. Chicks fledge in November and December, just when the summer-breeding burrowing petrels are getting started. Like most burrowing petrels, Great-wings arrive at their burrows after dark, to reduce their chances of being caught by predatory Antarctic skuas. Great-wings eat primarily squid caught at night.
