Pitcairn Islands, South Pacific.
This taxon was first recorded, and named “Procellaria atrata”, in 1769, during Captain Cook’s first voyage, but that account became known only later, in 1912, when species was formally described under present name. Thereafter it was long considered merely a dark morph of very variable P. arminjoniana, and the name “atrata” was not mentioned in HBW 1. Monotypic.
Tropical Pacific Ocean, breeding on Henderson I (Pitcairn Is), and recently found nesting on Easter I (c. 2000 km E of Henderson)#R; possibly also on some islands in French Polynesia, W of Pitcairns. Distribution in non-breeding period little known.
