North American least shrews carry a NatureServe S5 secure rank in Arkansas, and the record leans heavily toward GBIF (116 of 122 records), since a shrew this tiny and secretive is far more likely to turn up in a trap than in a photograph.
May, June, and July together account for 49 of the 122 records, exactly 40 percent of the total, tracking the shrew’s peak breeding-season activity, while January shows zero records at all, a gap that likely reflects reduced trapping effort in the coldest month rather than any true winter absence, since this species doesn’t hibernate.
