Description ⁸

Pinyon Mice reproduce from mid-February through mid-November, giving birth to litters of 3-6 blind, hairless young that weigh about 2.3 g each. The young have fur by the time they are two weeks old. At about 16-21 days, their eyes open and their ears unfold. They nurse for 3-4 weeks; sometimes a female becomes pregnant while she is still nursing a litter. These Mice are common in arid and semi-arid regions in the West, at elevations from sea level to more than 2,300 m. They are found most often among rocks where pinyon pine and juniper grow, but are not limited to this habitat.
