Range Description

Pterodroma atrata is known to breed only on Henderson Island, Pitcairn Islands (to UK), but may have also bred on Pitcairn Island in the past and has apparently become extirpated from Ducie, also in the Pitcairn Islands (Brooke 1995a). It is likely to breed on other islands in the region too (Murphy and Pennoyer 1952), such as the Gambier and Marquesas Islands (French Polynesia) (Murphy and Pennoyer 1952, Thibault and Bretagnolle 1999). In 1991-1992, the breeding population on Henderson was estimated at c.16,000 breeding pairs and it was suggested that the species could be undergoing a long-term decline (Brooke 1995a). While its non-breeding range is not well known, it has been sighted at Easter Island (A. Jaramillo in litt., 2011).
