Chipmunks are small, striped rodents of Sciuridae, the squirrel family; specifically, they are ground squirrels (Marmotini). 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 least chipmunk is the smallest species of chipmunk and the most widespread in North America.
Tamias is a genus of chipmunks in the tribe Marmotini of the squirrel family. The genus includes a single living species, the eastern chipmunk. The genus name Tamias means "treasurer", "steward", or "housekeeper", which is a reference to the animals' role in plant dispersal through their habit of collecting and storing food for winter use.
The Siberian chipmunk, also called common chipmunk, is native to northern Asia from central Russia to China, Korea, and Hokkaidō in northern Japan. It was imported from South Korea and introduced in Europe as a pet in the 1960s.
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.
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 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.
Ctenophthalmus pseudagyrtes is a species of fleas in the family Hystrichopsyllidae. It is widespread in North America, east of the Rocky Mountains, and is found mainly on small mammals. In Missouri, it has been recorded on the Virginia opossum, northern short-tailed shrew, eastern mole, raccoon, eastern chipmunk, Florida woodrat, prairie vole, woodland vole, white-footed mouse, including nests, marsh rice rat, hispid cotton rat, house mouse, and brown rat. Hosts recorded in Tennessee include the Virginia opossum, northern short-tailed shrew, eastern mole, eastern chipmunk, southern red-backed vole, rock vole, woodland vole, white-footed mouse, golden mouse, hispid cotton rat, marsh rice rat, and house mouse.
The Southern Great Lakes lowland forests is a temperate broadleaf and mixed forest ecoregion of North America, as defined by the World Wildlife Fund. Located near the Great Lakes, it lies mostly in the central northeastern United States and extends into southeast central Canada. In modern times, little of it remains intact due to land use, including agriculture and urban uses.
Tamias aristus is an extinct species of chipmunk that lived during the late Pleistocene epoch. It was characterized from a fossilized skull found in a limestone quarry in Ladds, Bartow County, Georgia. The name is derived from the Greek aristos, meaning noblest.
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.
Ixodes marxi is a species of tick, commonly known as the squirrel tick. It is a known vector of Powassan virus and can transmit the virus to human beings. These ticks can be found in numerous states of the United States as well as numerous Canadian provinces. Nymphs have been found on vegetation. Hosts include the eastern chipmunk, American red squirrel, Eastern gray squirrel, flying squirrels, snowshoe hares, foxes, and raccoons.
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.
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.
