Phalacrocorax kenyoni (Siegel-Causey, 1991:5)

Kenyon's shag, Amchitka cormorant

Taxonomy & Nomenclature

Synonym/s: Stictocarbo kenyoni Siegel-Causey, 1991:5 (original combination)

This species was tentatively synonymized with the extant P. pelagicus by (Rohwer et al. 2000) on the grounds that the three type specimens seem to belong to the latter species. However, they also found that at least some of the characters originally used by (Siegel-Causey, 1991) to diagnose P. kenyoni are also present in P. urile.
