Taxonomic Comments
See Patterson and Norris (2016) for a revised classification of Marmotini (Sciuridae: Xerinae), based on Thorington et al. (2012), Ge et al. (2014), and Patterson and Norris (2016); the three chipmunk lineages should be recognized as three distinct genera, namely, Tamias Illiger, 1811, Eutamias Trouessart, 1880, and Neotamias A. H. Howell, 1929. Thorington and Hoffmann (in Wilson and Reeder 2005) noted that chipmunks could be legitimately allocated to one (Tamias), two (Neotamias, Tamias), or three (Tamias, Neotamias, Eutamias) genera; they chose to adopt the single-genus (Tamias) arrangement.

Pre-1953 references to T. quadrivittatus in some cases pertain to T. umbrinus. Bergstrom and Hoffmann (1991) found species-specific vocalizations, habitats, and bacular characters in sympatric umbrinus and quadrivittatus, but convergence in electromorphs. Former subspecies rufus now is regarded as a distinct species (Patterson 1984).

Change Date1996-11-06
Range Extent Comments
Eastern California and northern Arizona to northern Colorado, southeastern and northwestern Wyoming, and extreme southwestern Montana (Hoffmann et al., in Wilson and Reeder 1993). Elevations of about 6500-11,000 ft.
Ecology & Habitat

Habitat

Coniferous forests. Often found near logs and brush in open areas and at edge of forests. Found in Transition, Canadian and Hudsonian life zones. Excavates burrows beneath rocks and shrubs.

Reproduction

Probably similar to other western chipmunks which mate in the spring and produce 1 litter of 4-5 altricial young following a gestation period of approximately 1 month. Young weaned and foraging on their own in mid-July or August
