![]() Inactive above ground from fall to spring, depend- ing on food reserves and minimum nightly temperature (Chew and Butterworth 1964, Bradley and Mauer 1973, Kenagy 1973a). Enters torpor under conditions of food-stress or low temperature (Bartholomew and Cade 1957, Chew and Butterworth 1964). Peak activity tends to occur early in the night (Kenagy 1973a). Species Life HistoryĪctivity Patterns: Nocturnal. Occurs in virtually all canopy coverage classes in most desert habitats. The nest chambers, 8 cm (3.2 in) wide by 5 cm (2.0 in) high, were found 52 and 65 cm (1.7 and 2.1 ft) beneath the surface. A burrow system excavated by Kenagy (1973a) had runway diameters of 1.5 to 2.0 cm (0.6 to 0.8 in). Reproduction: Nest made of green leaves and dry roots, usually beneath shrubs. Searches for seeds mainly beneath shrub canopy (Brown and Lieberman 1973).Ĭover: Sandy soil preferred for burrowing (Hall 1946), but also found commonly on gravel washes and on stony soils (Beatley 1976b, Miller and Stebbins 1964). Cheek pouches of pocket mice in Nevada contained seeds of Franseria, Plantago, Festuca, Eriogonum, and Chenopodium (Burt 1934, Hall 1946). In coastal scrub, grass seeds are eaten in summer, fall, and winter, and forb seeds are eaten in spring (Meserve 1976b). Green vegetation of grasses, forbs, or shrubs is consumed in spring (Bradley and Mauer 1973). Range Mapįeeding: Predominantly granivorous. ![]() Elevations range from sea level to 1700 m (5600 ft). Preferred habitats include desert riparian, desert scrub, desert wash, coastal scrub, and sagebrush. ![]() It also is found on the Northeastern Plateau in eastern Modoc and Lassen cos., and in the Los Angeles Basin south through coastal areas to Mexico. Range extends northward into southeastern Mono, Tulare, and Kern cos. The little pocket mouse is a common to abundant yearlong resident of the southern deserts.
