Audubon's Shearwater (Puffinus lherminieri)


Taxonomy

French: Puffin d’Audubon German: Audubonsturmtaucher Spanish: Pardela de Audubon
Taxonomy:

Pufflnus [sic] Lherminieri

Lesson

, 1839,

Antilles

.

Treated in HBW as comprising ten subspecies including P. bailloni, P. persicus and P. bannermani, but present races baroli and boydi were then treated as subspecies of P. assimilis. In recent past baroli and boydi have been split from P. lherminieri as one species#R or as two species#R, while in a third treatment baroli was split from lherminieri and boydi#R. Given that (a) the various points of morphological similarity and divergence in these taxa compose a mosaic of half-shared characters, (b) a recent molecular analysis#R identified a clade involving lherminieri, baroli and boydi, and (c) these three taxa are geographically grouped together in the N Atlantic, for the present we opt to retain them as one species, with race loyemilleri (breeding on islands off NW Panama) now regarded as synonym of nominate#R. Three subspecies currently recognized.
