White-footed mice are easy to confuse with Arizona’s cotton mice and deer mice, all close Peromyscus relatives sharing the same brushy, rocky ground, but this species leans toward the oak woodland and grassy canyon bottoms of the Sky Islands around Chiricahua National Monument, Coronado National Forest, and the San Pedro Riparian National Conservation Area.
Records carry four separate bumps, March, May, July, and September, rather than one clean peak, with May the strongest single month. That scattered, multi-peak shape likely reflects a mix of breeding activity and uneven trapping-survey timing more than a species with one true seasonal high, since this mouse forages actively through most of the year.
