Most of the specimens referable to _ruficaudus_ were taken in talus slides high in the Pend Oreille Mountains. A smaller series was collected at a lower altitude in open pine forests near Pend Oreille Lakes, Stevens County. I could detect no difference between _amoenus_ and _ruficaudus_ in habitat or habits. =Tamias townsendii= Bachman Townsend chipmunk _Description._--The Townsend chipmunk is the largest of the chipmunks that occur in Washington. Head and body measure about 5-1/2 inches; the tail about 4-1/2 inches. The fur of the Townsend chipmunk is more lax and less sleek than that of other species. The upper parts are duller and darker ochraceous. Stripes are wide and not sharply delineated. The dark stripes are deep chestnut or blackish. The upper pale stripe is pale buffy gray; the lower is whitish. The tail is blackish frosted with white above and rich ochraceous below. Underparts are dull white. The Townsend chipmunk ranges from the Fraser River in southern British Columbia through western Washington and Oregon, to central California. Like other members of the Pacific Coastal Fauna which extend southward to California, its geographic range extends farther inland to the south and geographic variation is greater; 3 races are listed by Johnson (1943: 114) in California. The Townsend chipmunk is the largest and darkest chipmunk in Washington. Over much of its range it is the only chipmunk found although in some mountainous areas both _townsendii_ and _amoenus_ occur together. The larger size and richer coloration, especially the rich tawny color of the underside of the tail, separate Townsend chipmunks from _amoenus_. [Illustration: FIG. 82. Townsend chipmunk (_Tamias townsendii cooperi_), captured on Goat Creek, 3,000 feet, western Cascade Mountains near Chinook Pass, Washington, September 16, 1940, by Earl J. Larrison; photographed February 1, 1941. (Fish and Wildlife Service photo by Victor B. Scheffer, No. 1139.)] Townsend chipmunks are closely associated with the coniferous forest where they live in clearings and tangles of underbrush such as on steep hillsides, fire slashings, snowslide areas or mountain glades. Though capable of swift movement, they are less nervous and active than other chipmunks. Rarely are they as abundant, even locally, as other species, and the home range of an individual seems to be larger than that of an _amoenus_ or a _minimus_. Rarely are more than two seen in a locality. Their more sedentary habits make them less conspicuous than other species. In the fall, when berries are dried out and seeds are ripe, they are most often seen. The Townsend chipmunk seems to be the most arboreal species found in Washington and individuals are not uncommonly seen in trees.
