| Uinta chipmunks are common in coniferous forests, especially at elevations higher than 1,800 m. They readily climb trees and shrubs to forage for seeds, and often sleep in trees. Females use tree cavities, and sometimes even take over abandoned birds' nests, to raise their young. Uinta chipmunks are found in several widely-separated populations, isolated on mountaintops surrounded by desert habitat the chipmunks cannot cross. Over the next many thousands of years, these disjunct populations may evolve into separate species.
Females are significantly larger than males.
