Threat ImpactHigh
Range Extent200,000 to >2,500,000 square km (about 80,000 to >1,000,000 square miles)
Number of Occurrences6 - 20
Rank ReasonsLimited number of breeding occurrences; apparent decline of almost 20 per cent 1995-2000; projected decline of greater than 20 per cent over next 3 generations (60 years).
Range Extent CommentsBREEDS: northwestern Hawaiian Islands (Kure east to Kaula) and on Torishima in Seven Islands of Izu (AOU 1998). Began breeding on San Benedicto Island, off the Pacific coast of Mexico, in 2000 (1 pair); apparently also nesting on Guadalupe Island, Mexico (Pitman and Ballance 2002). Formerly on northern Bonin, Volcano, Marianas and Marshall islands and Marcus, Wake and Johnston islands. RANGES: North Pacific south to Baja California, to Aleutians, Bering Sea (AOU 1998).
Occurrences CommentsBreeds on several northwestern Hawaiian Islands, on Torishima in Seven Islands of Izu (AOU 1998), and on San Benedicto and Guadalupe Islands, Mexico (Pitman and Ballance 2002). More than half of the breeding population nests at two sites: Laysan Island and Midway Atoll.
Threat Impact CommentsHistorically (until 1992) threatened by mortality from squid fishing and drift-nets. Currently, at least 3000 individuals estimated to die annually because of interactions with longline fisheries, perhaps many more (IUCN 2000). Other threats include pollution, introduced predators, oiling, ingestion of plastics, and the possibility of volcanic eruption on Torishima (IUCN 2000).
