The Colorado chipmunk (Neotamias quadrivittatus) is a species of chipmunk in the squirrel family Sciuridae. It is endemic to Colorado, Utah, Arizona and New Mexico in the United States. This species is the largest of the three species of chipmunks found in the Colorado Front Range (which also include the least chipmunk and the Uinta chipmunk). On average it weighs about 62 grams (2.2 oz). Chipmunks are distinguished from ground squirrels in that their faces have a stripe going across under the eye. There are no dimorphic differences between males and females.
Their vocalizations are essential for defending their territories. Three subspecies are recognized. N. q. quadrivittatus - Colorado, northern New Mexico, northern Arizona, eastern Utah The Colorado chipmunk primarily occupies coniferous forests in the Southern Rocky Mountains. In northeastern Colorado, the Colorado chipmunk's range is strictly bounded by competition with the higher-elevation Uinta chipmunk and it predominately occurs in open woodlands between 1,500 metres (4,900 ft) and 2,100 metres (6...

With luck
About 10% of wildlife watchers report a Colorado Chipmunk sighting in Rocky Mountain National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 27 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May and October–November
In those months about 20% of wildlife watchers report a Colorado Chipmunk in Rocky Mountain National Park on a given day, against under 5% in April and December–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Colorado Chipmunk sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Rocky Mountain National Park, in our data
Rocky Mountain National Park is the only park on Wallace's Line with enough records to rate Colorado Chipmunk sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Tamias
The closest relatives of the Colorado Chipmunk that you can see in Rocky Mountain National Park (genus Tamias, Eastern Chipmunks) are Least Chipmunk (about 20%) and Uinta Chipmunk (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Colorado Chipmunk is recorded against all the mammals logged in Rocky Mountain National Park (42 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.
