Brief Summary

Read full entry


Long-eared chipmunks are striking, with sharp, bright markings and the longest ears of any chipmunk. They live at middle elevations (970-2,290 m) in the Sierra Nevada Mountains. They sometimes nest in trees in summer, but more often den in secluded places on or near the ground. In November, they begin a four-month hibernation, first by adding about 20 percent to their body weight. They eat the same wide variety of foods as most chipmunks, including seeds, fungi, flowers, berries, the pupae of butterflies, and other insects.
