Character Abstract
Identification Comments:
Subspecies Comments:
Food Habits:Seeds are the primary food source. Also eats some insects. Does not appear to utilize free water. Believed to store food in seed caches within burrow system (O'Farrell and Blaustein 1974).
Phenology Comments:Activity observed March-October. Peak nocturnal activity occurs in first 2 hours after sunset. Moonlight and ambient temperature influence activity (O'Farrell and Blaustein 1974).
Reproduction Comments:Possibly polyestrous (Hall 1946); majority of young are born in May and June. Litter size is 2-7 (average 3.9).
Migration Mobility:Mice from the Mono region are sparated from other populations of the species by more than 100km of unsuitable habitat and represent a peripheral isolate on the western margin of the species' distribution (Hafner 1981; Hall 1941). Hafner et al 2006).
Habitat Comments:Sand-obligate desert rodent inhabiting stabilized sand dunes and sandy ridges and valleys in the Great Basin of western North America that support a floral community dominated by sagebrush (Artemisia) and rabbit brush (Chrysothamnus).
