Identification

Distribution

Mostly tropical, with the Caribbean, eastern Pacific, and Indian Ocean as main breeding grounds. All breeding grounds are islands. Subspecies subalaris breeds in the Galapagos Islands, and bannermani breeds off Japan.

Taxonomy

Heinroth's Shearwater and Persian Shearwater have been split from Audubon's Shearwater.

Subspecies

Audubon's Shearwater currently has a total of 9 subspecies. Two of these are treated in detail below, the rest are: lherminieri, loyemilleri, dichrous, gunax, bailloni, nicolae, and temptator (colstoni recognized by some authorities).

Subspecies subalaris

Status of Galapagos Shearwater subalaris

According to Boegh (2007), the Galapagos Shearwater (P. l. subalaris) is "now known to differ strikingly both in DNA (with high support), physiology and voice from the members of the Audubon's/Little complex. Indeed, they're not even the closest relatives of the Galapagos Shearwater, which actually is closer to the Christmas Shearwater." SACC (2008) treats subalaris as a full species, citing the genetic data of Austin et al (2004) and long-ago noted morphological distinctiveness by Murphy (1927). However, Clements 6th edition (2007) and Howard & Moore (2003) retain it as a subspecies of lherminieri, and the Opus follows in this consensus.

Status of Bannerman's Shearwater bannermani

Austin et al (2004) treat bannermani as a full species based on molecular phylogeny, and are followed by Onley & Scofield (2007). Sibley & Monroe (1996) also grant it species status. However, Clements 6th edition (2007) and Howard & Moore (2003) retain it as a subspecies of lherminieri, and the Opus follows in this consensus.
