Yellow-pine chipmunks favor open, sunny conifer forest and rocky clearings, exactly the mix of habitat that spans Glacier National Park’s lower forests, the Missouri River Breaks, and Custer-Gallatin National Forest, all named sites in the state’s 222-record set.
Records climb sharply into a July peak, more than 80 times the March low, tracking the heart of the active season when this day-active chipmunk is out foraging for seeds and insects before a long winter of hibernation. Every one of Montana’s records comes through GBIF rather than a photograph, and NatureServe rates the species secure (S5) statewide.
