SPECIES Tamiasciurus douglasii

Author:Bachman, 1838.
Actual Date:1839
Citation:Proc. Zool. Soc. Lond., 1838: 99.
Common Name:Douglas's Squirrel
Type Locality:"Shores of Columbia River" Restricted by J. A. Allen (1898:284) to mouth of Columbia River, [Clatsop Co., Oregon, USA].
Distribution:Coast and Cascade ranges and Sierra Nevada of SW British Columbia (not Vancouver Isl) (Canada) to S California (USA).
Status:IUCN Lower Risk (lc).
Comments: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.
