Perognathinae is a subfamily of rodents consisting of two genera of pocket mice. Most species live in complex burrows within the deserts and grasslands of western North America , They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches [ 2 ] to their burrows.
These pocket mice live in soils that may be vegetated with creosote bush, palo verde, burroweed, mesquite, cholla and other cacti, and short, sparse grass, as well as in lower edges of alluvial fan with yucca, mesquite, grama, and prickly poppy. Six subspecies are currently recognised: [4] C. pencillatus pencillatus - south-central Arizona
4. Predation Risk: Pocket mice living in highly vulnerable predator areas are less likely to scavenge for food and must do so with caution. 5. Type of soil: If the soil is too hard, pocket mice must find other means of obtaining their food. When a pocket mouse has found sufficient seeds, it will begin to store these resources in its fur-lined ...
The mating habits of cactus mice are currently not well studied, but are inferred from other Peromyscus species to be promiscuous. They mate year around, but more so during warmer months. Unlike other muroids, male cactus mice have a simple penis, rather than a complex one, and females have two pairs of teats, rather than three. The number of ...
Spinifex hopping mice live in small family groups of up to 10 individuals in deep, humid burrow systems. Typically, there is a large nest chamber lined with small sticks and other plant material about a metre below the surface, from which several vertical shafts lead upwards. Shaft entrances do not have spoil heaps.
For the study, Dinets, the lead author and assistant professor of psychology at the University of Tennessee, observed and studied the reptiles' pack-hunting habits while in Cuba.
The eastern harvest mouse mates during spring and autumn. The males are always prepared to mate while the females will not mate during the summer period. [3] The gestation period for pregnant females is ~21 days and they only need as little as 24 days to begin reproducing again. [2]
The California deermouse has very large ears, and its tail is longer than the head and body combined. Including the tail, which is about 117 to 156 mm (4.6 to 6.1 in) long, the mouse ranges in length from 220 to 285 mm (8.7 to 11.2 in). [6]
