Pyle et al., 2011,
Sand Island, Midway Atoll, north-central Pacific Ocean.
Description based on a 1963 specimen from Midway Atoll, originally identified as P. assimilis, but with several physical features suggesting closer alliance with P. lherminieri and relatives. Biometrics indicate that it is smaller than any other known shearwater, and phylogenetic analyses suggest that it diverged perhaps about two million years ago. Monotypic.
Insufficient data on breeding and non-breeding ranges. Singletons recorded in burrows at Midway Is, in NW Pacific Ocean, during winter (Feb and Dec–Jan, respectively); six individuals (one live and five dead) found in Bonin Is, S of Japan#R. Probably breeds in Bonin Is and ranges at sea in N Pacific Ocean#R.
