As their name indicates, Rock Pocket Mice dwell in rocky habitats, and only rarely live in areas with sandy or silty soils. Their inconspicuous burrows are located near or under rocks, in rocky gulches or canyons, or near boulders. The mouse pictured is sitting on a lava rock, probably in New Mexico, and the color of its fur blends with the dark rock. This is typical of pocket mice - their color often matches the background color of their habitat. Rock Pocket Mice breed from February or March through July, and young have been seen from April through August.
