Given Steve Howell's 2009 comments regarding a 3-way split of Oceanodroma leucorhoa, could a NAB subscriber please confirm whether the above article suggests a revised taxonomic treatment.

The complex:

• O l leucorhoa Leach's Storm Petrel
• O l chapmani 'San Benito Storm Petrel'
• O l socorroensis 'Socorro Storm Petrel'
• O l cheimomnestes 'Winter Storm Petrel'

Richard,
You mean this article: http://www.socalbirding.com/images/NAB_63-4_Leach_s_Storm_Petrel.pdf ?

Yes indeed. Many thanks, Daniel.

OK, so Steve Howell proposes to split O socorroensis as 'Townsend's Storm-Petrel' and O cheimomnestes as 'Ainley's Storm-Petrel'.

Tubenose books

It seems that we'll soon be spoilt for choice when it comes to tubenose guides!

Onley & Scofield 2007 (Field Guide to the Albatrosses, Petrels & Shearwaters of the World) will soon? be joined by Shirihai & Bretagnolle (Albatrosses, Petrels & Shearwaters of the World: a handbook to their taxonomy, identification, ecology & conservation), and Howell (Petrels, Albatrosses, & Storm Petrels of North America).

Mr. Howell published a small note discussing a “Western Specialty” with a picture of Chapman’s Storm Petrel in a recent Western Birds. http://www.westernfieldornithologists.org/journal.php .
Dark-rumped Leach’s Storm Petrel: “Birds like this one with variable whitish smudges on the sides of the rump are particularly frequent in the population breeding on Islas Los Coranados off Tijuana, B.C.”
Graf von Berlepsch described O. chapmani from the San Benito islands. (Oceanododroma [sic] leucorhoa willetti van Rossem, 1942, Proc. Biol. Soc. Washington, 55, p. 10 — Little Middle Island, Coronados Islands) So these birds are willetti but the merging of willetti and chapmani is supported by Bourne and Jehl (1982) and Power & Ainley (1986) as noted in the North American Birds article.


Howell gives English names for the two Guadalupe species to the scientists who originally described them. But he names chapmani for Frank Chapman not Hans Graf von Berlepsch! The scientist who originally described it. Graf von Berlepsch’s Storm Petrel, rolls off the tongue.

Graf von Berlepsch was not aware who collected these birds but I believe that it was either Horace A. Gaylord or A. W. Anthony who visited the islands in 1896. Anthony mistakenly called the birds there as O. soccorroensis as had whoever collected these type specimens. Charles Worthen, he of Worthen’s Sparrow fame who was a middleman for G. v. Berleplsch advertised in the Nidiologist the magazine Anthony discusses his trip to the San Benito Islands.

IOC Updates Diary July 7

Accept splits of Townsend’s Storm Petrel, Ainley’s Storm Petrel

IOC Version 6.3 (Draft) Species Updates

Townsend’s Storm Petrel Oceanodroma socorroensis

Townsend’s Storm Petrel is split from Leach’s Storm Petrel, and based on different vocalizations, morphology and from Ainley’s Storm Petrel O. cheimomnestes also by sympatry with seasonal isolation (Ainley 1980, Howell et al. 2009, Howell 2012,
NACC 2016-C-16).

Ainley’s Storm Petrel Oceanodroma cheimomnestes

Ainley’s Storm Petrel is split from Leach’s Storm Petrel, and based on different vocalizations, morphology and from Townsend’s Storm Petrel O. socorroensis also by sympatry with seasonal isolation (Ainley 1980, Howell et al. 2009, Howell 2012, NACC 2016-C-16).

TiF Update July 10, 2016

Leach's Storm-Petrel complex: Townsend's Storm-Petrel, Cymochorea socorroensis, and Ainley's Storm-Petrel, Cymochorea cheimomnestes, have been split from Leach's Storm-Petrel, Cymochorea leucorhoa. Besides the references listed in the AOU proposal, Adams et al. (2016) and Bicknell et al. (2012) are useful when considering the Leach's complex.
