Chipmunks are small, striped rodents of subtribe Tamiina. Chipmunks are found in North America, with the exception of the Siberian chipmunk which is found primarily in Asia.
The eastern chipmunk is a chipmunk species found in eastern North America. It is the only living member of the genus Tamias.
The alpine chipmunk is a species of chipmunk native to the high elevations of the Sierra Nevada of California. No significant threats to the species are known.
The gray-footed chipmunk is a terrestrial and forest-dwelling species of chipmunk and rodent in the family Sciuridae. It is endemic to New Mexico and in the Sierra Diablo and Guadalupe Mountains in the Trans-Pecos region of Texas in the United States. Its natural habitat are coniferous forests. First discovered in 1902, they are distinguished by the unique gray dorsal colouring on the hind feet, hence the common name. They demonstrate sexual dimorphism, and the female is larger than the male.
Palmer's chipmunk is a species of rodent in the family Sciuridae, endemic to Spring Mountains in southern Nevada. Its natural habitat is temperate forests. Palmer's chipmunks are limited to "sky islands" which are mountainous habitats that are surrounded by other lower elevation inhospitable habitats. It is primarily threatened by habitat loss. Palmer's chipmunk is named after Theodore Sherman Palmer, an American botanist and zoologist. With adequate habitat and food resources Palmer's chipmunks typically live from 1 to 4 years.
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 Sonoma chipmunk 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 two premolars. N. sonomae has two subspecies: N. s. alleni and N. s. sonomae.
The Lodgepole chipmunk is a species of rodent in the family Sciuridae. It is found in the U.S. state of California at elevations from 1,500 to 3,000 metres. The Lodgepole chipmunk has a variety of common names including: Tahoe chipmunk, Sequoia chipmunk, Mt. Pinos chipmunk, and San Bernardino chipmunk.
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.
The Ezo chipmunk is a subspecies or local population of the Siberian chipmunk; it is found in what was once known as Ezo, namely Hokkaidō, Japan, and Sakhalin and the Southern Kuriles, Russia.
The Ohio chipmunk, also known as the Ohioan chipmunk, or the Ohio eastern chipmunk, is a subspecies of the eastern chipmunk that is native to parts of Wisconsin, Illinois, Indiana, Michigan, Kentucky, and Ohio, with some populations potentially present in far north-eastern to western Pennsylvania, and very rarely into West Virginia. It was described by Patterson Bole and Philip Moulthrop in 1942. The subspecies has a very similar coloration, and appearance to that of other subspecies.
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.
Fremont's chipmunk, or Fremont's Uinta chipmunk, is a subspecies of the Uinta chipmunk that is endemic to parts of Wyoming.
The mountaineer chipmunk, also known as the mountaineer Uinta chipmunk, southern Rocky Mountains chipmunk, or the southern Rocky Mountains Uinta chipmunk, is a subspecies of the Uinta chipmunk that is native to parts of Colorado, southwestern Wyoming, and far northeastern Utah. It may overlap with the nominate subspecies, Neotamias umbrinus umbrinus in northeastern Utah.
