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.

The three type specimens of this species are recent specimens collected on 15 September 1957 (the two paratypes) and 22 February 1959 (the holotype). The remains of this species were also found in middens on Amchitka Island, one of the far western Aleutian Islands, between Russia and Alaska (Siegel-Causey, 1991).
