Tamiasciurus douglasii (Bachman 1838)

[Sciurus] douglasii Bachman 1838 , Proc. Zool. Soc. Lond., 1838: 99.

Type Locality: "Shores of Columbia River" Restricted by J. A. Allen (1898:284) to mouth of Columbia River, [Clatsop Co., Oregon, USA].

Vernacular Names: Douglas's Squirrel.

Subspecies: :

Subspecies Tamiasciurus douglasii subsp. douglasii Bachman 1838

Subspecies Tamiasciurus douglasii subsp. mollipilosus Audubon and Bachman 1841

Distribution: Coast and Cascade ranges and Sierra Nevada of SW British Columbia (not Vancouver Isl) ( Canada) to S California ( USA).

Conservation: IUCN – Lower Risk (lc).

Discussion: Formerly included mearnsi ; see Lindsay (1981). Hall (1981:466) suggested that douglasii might be conspecific with hudsonicus , but Lindsay (1982) showed that apparent hybrids were probably due to character convergence. Reviewed by Steele (1999, Mammalian Species No. 630). Arbogast et al. (2001) found that mitochondrial DNA differed only slightly among the three species of Tamiasciurus .
