Neotamias minimus is the smallest species of chipmunk. It is widely distributed in northern and western North America: from the Yukon eastwards to James Bay and the Great Lakes, and southwards to California and New Mexico (Map). Up to 21 subspecies have been described, including N. m. neglectus, shown on this page. Least Chipmunk is found in coniferous and mixed forests, riparian habitats, clearcuts, sagebrush, and alpine tundra. It feeds mostly on seeds, nuts, fruits, and insects. This species is less arboreal than other chipmunks. N. minimus enter long periods of torpor in late October-November, but does not truly hibernate; it is fully active by March-April.
