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 least chipmunk is the smallest species of chipmunk and the most widespread in North America.
The Hopi chipmunk, Neotamias rufus, is a small chipmunk found in Colorado, Utah and Arizona in the southwestern United States. It was previously grouped with the Colorado chipmunk, T. quadrivittatus. This species is listed as "Least Concern" on the IUCN Red List as it is common, widespread, and without any major threats. It was last evaluated in 2016.
The cliff chipmunk is a small, bushy-tailed squirrel that typically lives along cliff walls or boulder fields bordering Pinyon-juniper woodlands in the Western United States and Mexico. Cliff chipmunks are very agile, and can often be seen scaling steep cliff walls. Cliff chipmunks do not amass body fat as the more common ground squirrel does. They create caches of food which they frequent during the cold winter months.
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.
Merriam's kangaroo rat is a species of rodent in the family Heteromyidae. The species name commemorates Clinton Hart Merriam. It is found in the Upper and Lower Sonoran life zones of the southwestern United States, Baja California, and northern Mexico.
The yellow-pine chipmunk is a species of order Rodentia in the family Sciuridae. It is found in parts of Canada and the United States.
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.
The gray-collared chipmunk is a species of rodent in the family Sciuridae. It is endemic to Arizona and New Mexico in the United States.
The yellow-cheeked chipmunk, also known as the redwood chipmunk, is a species of rodent in the squirrel family, Sciuridae. It is endemic to areas near the coast of northern California in the United States where it inhabits coastal coniferous forest.
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.
The long-eared chipmunk, also called the Sacramento chipmunk or the four-banded chipmunk, is a species of rodent in the squirrel family, Sciuridae. It is endemic to the central and northern Sierra Nevada of California and Nevada in the United States. Long-eared chipmunks have the longest ears of all species of chipmunks.
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.
The red-tailed chipmunk is a species of rodent in the family Sciuridae. It is found in Alberta and British Columbia in Canada and Montana, Idaho and Washington 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 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.
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.
