| Summary: | 185. Colorado Chipmunk Tamias quadrivittatus French: Tamia du Colorado / German: Colorado-Backenhornchen / Spanish: Ardilla listada de Colorado Taxonomy. Sciurus quadrivittatus Say, 1823, “[Arkansas River].the place where the . river leaves the mountains:.” » Restricted: by C. H. Merriam in 1905 to about 26 mi. [42 km] below Canon City, Fremont County, Colorado. Three subspecies are recognized. Subspecies and Distribution. HT gq. quadrivittatus Say, 1823 — E Utah, Colorado, N Arizona, N New Mexico, and extreme W Oklahoma (USA). T.q.australisPatterson,1980—OrganMts,SCNewMexico(USA). T: q. oscuraensis Sullivan, 1996 — Oscura Mts, C New Mexico (USA). Descriptive notes. Head-body 125-3-132 mm, tail mean 99-6 mm; weight 45-2— 69-8 g. The Colorado Chipmunk has a dark gray to black mid-dorsal stripe and two lateral dark stripes, which are slightly paler than mid-dorsal stripe.

Subspecies oscuraensis is smaller than other subspecies and has reddish sides and a reddish brown dorsal surface on feet. Chromosome number of the Colorado Chipmunk is 2n = 38. Karyotype is type B for Tamias and consists of five pairs of metacentric autosomes, six pairs of submetacentric autosomes, seven pairs of acrocentric autosomes, a submetacentric X chromosome, and an acrocentric Y chromosome. Habitat. Rocky areas. The Colorado Chipmunk occurs in several types of vegetation, such as ponderosa pine forests (Pinus ponderosa, Pinaceae), spruce-fir forests (Picea, Pseudotsuga, Abies, all Pinaceae), pinyon-juniper (Pinus; Juniperus, Cupressaceae) or scrub oak (Quercus, Fagaceae) vegetation, desert shrub, and even alpine tundra.
