The eastern chipmunk (Tamias striatus) is a chipmunk species found in eastern North America. It is the only living member of the genus Tamias. The name "chipmunk" probably comes from the Ojibwe word ᐊᒋᑕᒨ ajidamoo (or possibly ajidamoonh, the same word in the Ottawa dialect of Ojibwe), which translates literally as "one who descends trees headlong." First described by Mark Catesby in his 1743 The Natural History of Carolina, Florida, and the Bahama Islands, the chipmunk was eventually classified as Sciurus striatus by Linnaeus, meaning "striped squirrel" in Latin. The scientific name was changed to Tamias striatus, meaning "striped steward", by Johann Illiger in 1811.
A small species, it reaches about 30 cm (12 in) in length including the tail, and a weight of 66–150 g (2.3–5.3 oz). It has reddish-brown fur on its upper body and five dark brown stripes contrasting with light brown stripes along its back, ending in a dark tail. It has lighter fur on the lower part of its body. It has a tawny stripe that runs from its whiskers to below its ears, and light stripes over its eyes. It has two fewer teeth than other chipmunks and four toes each on the front... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Eastern Chipmunk is recorded against all the mammals logged in Great Smoky Mountains National Park (92 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
