Giant petrel

Giant petrels form a genus, Macronectes, from the family Procellariidae, which consists of two species. They are the largest birds of this family. Both species are restricted to the Southern Hemisphere, and though their distributions overlap significantly, with both species breeding on the Prince Edward Islands, Crozet Islands, Kerguelen Islands, Macquarie Island and South Georgia, many southern giant petrels nest further south, with colonies as far south as Antarctica. Giant petrels are aggressive predators and scavengers, inspiring another common name, the stinker. South Sea whalers used to call them gluttons.
