picture info	Chipmunk Chipmunks are small, striped rodents of the family Sciuridae. Chipmunks are found in North America, with the exception of the Siberian chipmunk which is found primarily in Asia. Taxonomy and systematics Chipmunks may be classified either as a single genus, ''Tamias'', or as three genera: ''Tamias'', of which the eastern chipmunk (''T. striatus'') is the only living member; ''Eutamias'', of which the Siberian chipmunk (''E. sibiricus'') is the only living member; and ''Neotamias'', which includes the 23 remaining, mostly western North American, species. These classifications were treated as subgenera due to the chipmunks' morphological similarities. As a result, most taxonomies over the twentieth century have placed the chipmunks into a single genus. However, studies of mitochondrial DNA show that the divergence between each of the three chipmunk groups is comparable to the genetic differences between ''Marmota'' and ''Spermophilus'', so the three genera classifications have b ...

	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'')''.'' Its coat is brown-gray, with a pattern of five dark brown and four gray stripes along its back; the central stripe tends to be blackish and darker in color compared to the other stripes. Additionally, ''Neotamias siskiyou'' have three brown and two gray stripes on each cheek. The specific appearance of the Siskiyou chipmunk varies due to the large geographic range the species inhabits, with larger and darker members found on the coasts compared to those found further inland.

	Allen's Chipmunk Allen's chipmunk (''Neotamias senex'') is a species of chipmunk. It is also known as the shadow chipmunk. It is native to the western United States, where it occurs in California, Nevada, and Oregon. It is a common species of the Sierra Nevada. ''Neotamias senex's'' length measures about 229-261 mm. Female chipmunks are larger compared to males, with a dimorphism ratio of 1.033. Females weigh around 73.0 grams to 108.5 grams, while males weigh 66.8 grams to 99.3 grams. This chipmunk generally prefers mature coniferous forests and chaparral slopes dominated by ponderosa pine, Jeffrey pine, sugar pine, black oak, Douglas fir, white fir, red fir, incense cedar, and mountain hemlock.

picture info	Sonoma Chipmunk The Sonoma chipmunk (''Neotamias sonomae'') is a species of rodent in the squirrel family Sciuridae. It is endemic to northwestern California in the United States. Members of Neotamias are characterized by having 2 premolars. ''N. sonomae'' has 2 subspecies: ''N. s. alleni'' and ''N. s. sonomae''. Distribution The Sonoma chipmunk is only found in California, north of the San Francisco Bay. Most of its range is within Sonoma and Marin counties. Habitat Sonoma chipmunks are found in areas of forest or chaparral. They can be found in forests of sticky laurel, Ponderosa pine, Douglas fir, spruce, redwood, and black oak. They are generally associated with coniferous forests. The chaparral that Sonoma chipmunks inhabit is characterized by sagebrush plains. Sonoma chipmunks are found in elevations from 0 to 1800 m. These chipmunks typically live on the ground and make burrows in the ground, but they can climb and may make nests in trees. Physical characteristics The Sonoma ch ...

	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 .

picture info	Townsend's Chipmunk Townsend's chipmunk (''Neotamias townsendii'') is a species of rodent in the squirrel family, Sciuridae. It lives in the forests of the Pacific Northwest of North America, from extreme southwestern British Columbia through western Washington and western Oregon. Townsend's chipmunk is named after John Kirk Townsend, an early 19th-century ornithologist. Description A large chipmunk, adults can be from nose to the tip of its tail. In much of its range, it is the only chipmunk; it can be identified by its tail which is grayish above and reddish below, and by its brown coloration with indistinct tawny stripes.
