The hispid pocket mouse is a coarse-furred grassland rodent that most Arizonans will never lay eyes on, a burrowing seed-eater known in the state largely from museum specimens and field surveys rather than casual photographs. Occurrence databases hold 175 Arizona records, the great majority of them specimen and GBIF occurrence data.
A mouse of the southeastern grasslands
In Arizona this is a species of the southeast corner, concentrated in Cochise County with lighter tallies in Santa Cruz and Pima. It belongs to open, grassy country: the high desert-grassland valleys, sandy uplands, and dry washes that skirt the Sky Island ranges, not the cactus flats or bare rock other pocket mice favor. The grasslands around Chiricahua National Monument, the Coronado National Forest foothills, and the San Pedro River corridor sit squarely in its range.
Secure across the Plains, rarely seen in Arizona
The thin Arizona record set is a story about detectability, not scarcity elsewhere. NatureServe ranks the hispid pocket mouse S5, secure, and it’s genuinely widespread across the central and southern Great Plains; in Arizona it simply lives a life that keeps it off camera. It’s nocturnal, spends its days underground, forages quietly for seeds it stuffs into fur-lined cheek pouches, and turns up mostly when a live-trapping survey catches one.
Status in Arizona
Hispid pocket mouse is native to Arizona, and NatureServe ranks it S5, secure. The rise in late-summer and autumn records here tends to follow monsoon plant growth and the fieldwork that comes with it, rather than marking any true peak in the animal’s year.
