Least Chipmunk
The least chipmunk (''Neotamias minimus'') is the smallest species of chipmunk and the most widespread in North America. Description It is the smallest species of chipmunk, measuring about in total length with a weight of . The body is gray to reddish-brown on the sides, and grayish white on the underparts. The back is marked with five dark brown to black stripes separated by four white or cream-colored stripes, all of which run from the nape of the neck to the base of the tail. Two light and two dark stripes mark the face, running from the tip of the nose to the ears. The bushy tail is orange-brown in color, and measures long. In some areas, where range overlap with the yellow-pine chipmunk occurs, it may be difficult or impossible to distinguish the two species in the field; laboratory examination of skeletal structures may be required. As in other chipmunks, there are four toes on each of the forefeet and five on the hindfeet. Females have eight teats. The brain to body mass ...

Uinta Chipmunk
The Uinta chipmunk or hidden forest chipmunk (''Neotamias umbrinus''), is a species of chipmunk in the family Sciuridae. It is endemic to the United States. Formerly known as ''Tamias umbrinus'', phylogenetic studies have shown it to be sufficiently distinct from the eastern chipmunk as to be placed in a separate genus, ''Neotamias''. The same studies have also suggested that Palmer's chipmunk may actually be a subspecies of Uinta chipmunk, although the two are still generally regarded as separate species. Description The Uinta chipmunk is a medium-sized chipmunk, with adults ranging from in length, including the tail at , and weighing an average of . The predominant color of the summer coat varies from yellowish brown-grey to dark brown, often with a reddish tinge.

Townsend's Chipmunk
Townsend's chipmunk (''Neotamias townsendii'') is a species of rodent in the squirrel family, Sciuridae.

Siskiyou Chipmunk
The Siskiyou chipmunk (''Neotamias siskiyou'') is a species of rodent in the family Sciuridae. It is endemic to northern California and central Oregon in the United States. Anatomy and morphology The Siskiyou chipmunk is closest in appearance to Allen's chipmunk (''Neotamias senex'') and the yellow-cheeked chipmunk (''Neotamias ochrogenys'')''.''
