Nelson's Pocket Mice live in the Chihuahuan Desert of north-central Mexico and adjacent parts of western Texas and southern New Mexico. They are found mostly in rocky areas where there are some shrubs to provide cover. Kangaroo rats, woodrats, and deermice are often found in the same habitat. Many species of pocket mice become inactive during the winter, but Nelson's Pocket Mouse remains active all year, feeding on shrub and grass seeds. Only about 14 percent live longer than one year.
