Adaptations
The Desert mouse is usually found in North America in the regions of California, Colorado, Mexico and Southwestern United states along with other desert animals. As the name suggests, the desert mouse prefers to live in areas that have a desert-like habitat. They are territorial creatures who prefer solitary.

Diet
What does a desert mouse eat? It mostly feeds on seeds of the mesquite, creosote, broomweed and palo verde tree or forbs. Along with that, it also feeds on grass, shrubs and sometimes insects. A desert pocket mouse stores the seeds that it collects in burrows and dispersed caches. Nothing much is known about their water consumption, except for the fact that they take the water content from the foods that they eat.

Habitat
The desert mouse excavates its burrows in sandy, silty or gravelly soils. They prefer soft alluvial soils that are found near stream bottoms, desert washes and valleys. The desert mouse is not found near the rocks. They dig out the soil from these places to make their burrows near the base of bushes. These burrows are closed in the daytime.

The desert mouse is a nocturnal creature. This creature is active throughout the year but maybe inactive during the winter season. They do not migrate to any other region during the winter, but might hibernate in the burrows during this time. Their young are born and raised in the burrow chambers that are especially dug out.

The breeding season of the desert mouse begins in late February and lasts till September. Most young are born in the months from April till May, while the number dips in June till August. The gestation period lasts for 23 days. The female will have a litter of 2-6 pinkies. It is difficult for the young to survive and only about 5% of these will survive. Another interesting fact about the desert mouse young is that the female pups will reach sexual maturity early on and will become pregnant while still young.
