North American least shrews carry a NatureServe S4 apparently secure rank in Nebraska, and nearly all of the state’s 40 records, 39 of them, come from GBIF rather than casual photographs, since this tiny shrew is far more often caught in a trap than spotted.

November alone accounts for 15 of the year’s monthly-tallied sightings, more than a third of the total, with September adding another 9, a fall-heavy pattern that likely tracks trapping-survey timing rather than any real seasonal surge, since this shrew stays active year-round without hibernating.
