Colorado Chipmunk
Look first for large chipmunk with dark facial stripes and warm ochre sides, then confirm it in rocky foothills, canyon walls, and open woodland in the central southwest. Those two clues make Colorado Chipmunk much easier to identify responsibly in Colorado.

Colorado chipmunks occupy rocky slopes, canyon country, and open woodland from Colorado into neighboring parts of Utah, Arizona, and New Mexico. Facial stripes, body size, geography, and voice all matter because several chipmunk species overlap in the state.
Observe natural foraging rather than feeding picnic-ground animals. Photograph the face and flank, record habitat and elevation, and resist confident identification where Hopi, Uinta, least, or cliff chipmunks may occur.
- Status
- Secure regional species; often confused with neighboring chipmunks
- Best clue
- Large chipmunk with dark facial stripes and warm ochre sides
- Colorado habitat
- Rocky foothills, canyon walls, and open woodland in the central Southwest
Quick guide
- Look
- Rock walls and open woodland below high alpine zones
- Confirm
- Photograph face, flanks, and rump in one sequence
Read Colorado Chipmunk in four field decisions
- Start with size
- Colorado Chipmunks appear robust, with a long tail and warm ochre wash along the sides.
- Read the face
- Dark facial stripes remain strong, but angle and shadow can make stripe counts unreliable.
- Check geography
- Use elevation and location to separate overlapping Least, Uinta, and Hopi chipmunks.
- Do not feed
- Food handouts erase natural foraging behavior and can pull chipmunks toward roads and people.
Good to know
The strongest Colorado Chipmunk record preserves the distinction between “Large chipmunk with dark facial stripes and warm ochre sides” and “Rocky foothills, canyon walls, and open woodland in the central Southwest” while also showing the surrounding habitat.
