The long-tailed pocket mouse turns up in a narrow corner of Arizona. Open databases hold 308 Arizona records, and nearly all of them come from just two counties tucked against the state’s northwestern border.
Arizona Strip country, not the Sonoran Desert
Mohave County holds 235 of those records and Coconino County another 67, together accounting for nearly every report filed for this species in the state. Both counties sit in Arizona’s far northwest, where the Mojave Desert’s rocky slopes and canyon washes reach south from Nevada and Utah across the Arizona Strip and the plateau country west of the Grand Canyon. Only a couple of records turn up anywhere near Phoenix or Tucson, so this pocket mouse’s Arizona range reads like a thin extension of Mojave and Great Basin habitat rather than a Sonoran Desert animal.
A tail longer than its body, a burrow full of seeds
The giveaway is the tail: it runs noticeably longer than the head and body combined, tipped with a small tuft of hair. Fur-lined cheek pouches open beside the mouth and let the mouse carry dry seeds home without wetting them, separating gathering from eating. It forages after dark on rocky slopes and gravelly desert ground, then empties its pouches into an underground cache and spends the heat of the day below ground, where the air stays cooler and moisture is easier to hold onto.
Status in Arizona
NatureServe ranks the long-tailed pocket mouse S5, secure, and it’s native to Arizona. Its narrow foothold in the state’s far northwest looks stable, tied to the same rocky Mojave Desert terrain that supports it across Nevada, Utah, and California.
