Texas deermice stick to rocky hills and wooded canyons, exactly the terrain at Balcones Canyonlands, across the Hill Country, and along Devils River, where broken limestone ledges and oak-juniper cover give this large-eared, white-footed mouse the crevices it dens in. Almost all of the state’s 946 records come from GBIF specimen data rather than photographs, since a mouse this compact and nocturnal rarely gets caught on camera.

Records spike in March, ease, then rise again in May and August rather than settling on one peak, a scattered pattern more typical of trapping surveys than a single breeding season. Texas ranks the species occasional, at the 36th percentile among the state’s mammals and well below the record density of its Hill Country neighbors, though NatureServe still lists it S5, Secure statewide.
