Summary ³

The Great Basin pocket mouse (Perognathus parvus) is a species of rodent in the family Heteromyidae. It is found in British Columbia in Canada and the western United States.

Description ⁴

The Great Basin Pocket Mouse is the largest member of the genus. It inhabits arid and semi-arid habitats in nearly the entire Great Basin region of western North America, particularly where sagebrush dominates the vegetation. The Mice increase the amount of water available from the small seeds they eat by storing them in the burrow, where humidity is higher than it is aboveground - the seeds actually absorb water while they are stored. Great Basin Pocket Mice become inactive from about November through March, entering torpor for long periods of time. The breeding season begins in April and ends as early as July in the northern part of the range, and as late as October farther south. Females have 1-3 litters of 2-8 young annually, though they may not breed during a drought.
