Description

"Canyon Mice inhabit arid shrublands and grasslands in the inhospitable ""slickrock"" deserts of the West. In the canyons where they live, the common denominator is bare rock, and they are remarkably agile at scampering on vertical or even overhanging walls. Where they are in competition with other mice, canyon Mice live in rockier, more desolate areas and the other, larger species use the areas with trees or shrubs. When they can, canyon Mice feed mostly on green vegetation and insects, but when those are not available, fruits and seeds are the mainstays of their diets. They are active all year long, but probably enter torpor if food (and therefore the water they need, which they obtain from food) is scarce."
