Habitat:
It nests in colonies on islets or islands at low altitude, often coral atolls or volcanic islands, and feeds mainly on squid, supplemented by fish and crustaceans; it may obtain much food by following cetaceans (Holyoak and Thibault 1984, Carboneras 1992). Records on land are up to 475 m above sea level (GBIF.org 2022).
Range:
Pterodroma alba breeds in the Line and Phoenix Islands (Kiribati), Marquesas Islands (French Polynesia), and Pitcairn Islands (to UK) (c.12-20 pairs on Oeno in 1997 and 1998 [Bell and Bell 1998, B. Bell pers.comm 1999]). In the Line Islands, the stronghold is Kiritimati (= Christmas Island). During the non-breeding season, the species disperses over much of the tropical Pacific as far north as Hawaii and as far south as the Kermadec Islands (Gangloff et al. 2009).
Conservation:
Conservation Actions Underway
On Kiritimati, a cat eradication programme has failed to limit predation by feral cats outside villages (M. Rauzon in litt. 1999, E. A. Schreiber in litt. 1999). There are plans to attract the species to cat-free Jarvis Island National Wildlife Refuge (200 miles from Kiritimati) using acoustic playback recorders (Rauzon 1985). On Oeno and Ducie, the Polynesian Rat Rattus exulans was successfully eradicated in 1997 (B. Bell pers. comm 1999). In the Marquesas Islands, there is work ongoing to keep protected areas free of introduced predators (P. Raust in litt. 2012). Biosecurity action plans have been completed for Kiribati, some of the Line Islands, and some of the Pitcairn Islands (Pierce et al. 2020).
Conservation Actions Proposed
Monitor breeding populations at key sites. Survey for and control invasive species on key breeding islands. Improve biosecurity for key breeding islands. Restore former breeding sites that are currently overrun by invasive species. Restore populations using translocations and audio lures (Pierce et al. 2020), for example to attract the species to cat-free Jarvis Island National Wildlife Refuge (200 miles from Kiritimati), using acoustic playback recorders. Research the species's biology and threats to help guide recovery efforts, and raise local public awareness with regards to the threat of hunting (Pierce et al. 2020).
