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.
The Colorado chipmunk is a species of chipmunk in the squirrel family Sciuridae. It is endemic to Colorado, Utah, Arizona and New Mexico in the United States.
Allen's chipmunk, also known as the shadow chipmunk, is a species of chipmunk native to the western United States. Occurring in California, Oregon, and Nevada, it is a common species of the Sierra Nevada.
The Siskiyou chipmunk is a species of rodent in the family Sciuridae. It is endemic to northern California and central Oregon in the United States.
The Uinta chipmunk or hidden forest chipmunk, 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.
There are at least 50 small mammal species known to occur in Yellowstone National Park.
Neotamias is a genus of chipmunks within the tribe Marmotini of the squirrel family. It contains 23 species, which mostly occur in western North America. Along with Eutamias, this genus is often considered a subgenus of Tamias.
There are 67 native species of mammals in Rocky Mountain National Park, a 265,461 acres (107,428 ha) park in Colorado. Species are listed by common name, scientific name, habitat, and abundance. Species which are extirpated, or locally extinct, are marked with an EX.
Tamias striatus doorsiensis is a subspecies of the eastern chipmunk that is only found in Door, Kewaunee, northeastern Brown, and possibly Manitowoc counties in northeastern Wisconsin. It was described by C. A. Long in 1971. Compared to the other subspecies of eastern chipmunk present in nearby in Michigan and Wisconsin, they have brighter patches behind their ears, grayer hair along their backs, and more white on their tails. It is smaller than T. s. griseus but larger than the least chipmunk.
The Inyo chipmunk, or the Inyo Uinta chipmunk, is a subspecies of the Uinta chipmunk that is native to parts of central Nevada and eastern California, going into far north Arizona. It was described by Clinton Hart Merriam in 1897.
The Mount Ellen chipmunk, or the Mount Ellen Uinta chipmunk, also spelt as the Mt. Ellen chipmunk, is a rare subspecies of the Uinta chipmunk that is endemic to Mt. Ellen, Henry Mountains, Garfield County, Utah. Not many threats persist for the subspecies, so the current conservation status refers to it limitedness in the region. It is listed as "Critically Imperiled" by NatureServe because of its limited natural range.
Fremont's chipmunk, or Fremont's Uinta chipmunk, is a subspecies of the Uinta chipmunk that is endemic to parts of Wyoming.
