Crawford’s gray shrew breaks the usual shrew mold twice over: it survives desert scrub instead of damp ground, and it keeps hunting insects after dark with a metabolism that barely lets up. New Mexico turns out to be one of its real strongholds, with 189 records, second only to California’s 285 and well ahead of Arizona, Texas, and Colorado.

Reports concentrate around Gila National Forest and rise through summer, peaking in August, likely reflecting when field surveys ran rather than a true seasonal shift in a nocturnal hunter that stays active year-round.

NatureServe lists the species S4, Apparently Secure, in New Mexico, consistent with the state’s importance for a shrew that’s otherwise easy to overlook across its dry Southwest range.
