Non-migratory.

Habitat
In w. MT uses open stands of ponderosa pine and Douglas fir. Will use open grassland if cover is adequate. In absence of T. ruficaudus & T. minimus in central MT, T. amoenus ranges into subalpine forests & alpine tundra. (Hoffmann and Pattie 1968, Beg 1969).

Food Habits
Primarily fruits and seeds. Leaves and fruits important in spring, less so in summer, insignificant in fall. Occasion- ally eats arthropods. Seasonal shifts related to availabi- lity (Beg 1969).

Ecology
Contiguous allopatry with other chipmunk species (Beg 1969). Nest chamber in burrow which averages 11 inches below surface (Banfield 1974). In association with T. ruficaudus, will occupy lower elevations.

Reproductive Characteristics
Breed around April. Pregnant April-May. Give birth May- June. Lactation stops around mid to late June. (Beg 1969).
