Chipmunks can be hard to identify from afar, so knowing what habitat types certain species prefer can really narrow-down your options. Here in western Montana, three species regularly co-occur (Red-tailed, Yellow-pine, and Least). Red-tailed Chipmunks tend to prefer moist coniferous forests like those in Glacier National Park, while Yellow-pine Chipmunks tend to prefer drier, Ponderosa/Doug-Fir forest edges. Least Chipmunks are found everywhere in between including alpine, sagebrush, coniferous forests, and meadows.
