Silky pocket mouse turns up across the open grassland and shrubland of the Trans-Pecos, with Big Bend, the Guadalupe Mountains, and the Davis Mountains anchoring the record set. It’s a small, seed-eating rodent that’s active at night and rarely seen by casual visitors, and the data shows it: of 48 Texas records, only 9 come from iNaturalist photos, and the rest are GBIF specimen and survey records built up through decades of trapping work.

Records pile up hard in summer, with July and August together holding 360 of the 48 records, almost certainly reflecting when small-mammal surveys ran rather than a true seasonal spike in the animal itself.

NatureServe lists it S5, Secure, in Texas, matching its Secure (G5) status across its full range.
