The species has also bred at least once on Ile des Pingouins (Crozet Islands, French Southern Territories). Non-breeding birds range widely through the south Pacific, with large numbers found along the Peru Current (2). Scarce in the southern Indian Ocean (2), and only a rare visitor to the South Atlantic (4).
