Montane shrew in Arizona is restricted to the cool, moist forest floor of the state’s highest Sky Island and White Mountains ranges, and its mid-tier record traces almost entirely to two months of the year.
August and September together account for every logged sighting, which reads as trapping-survey timing rather than a true two-month activity window; a shrew this small and this seasonally undersampled needs a longer record before any real seasonal pattern can be claimed.
