Plains harvest mice carry a NatureServe S4 apparently secure rank in Nebraska, and the record leans heavily toward GBIF (51 of the state’s 53 records) over iNaturalist (6), since this tiny grassland mouse is far more often caught in a trap than photographed.
Records build through the year to a late peak, November and December together account for 19 of the year’s monthly-tallied sightings, more than a third of the total, a pattern that likely tracks fall trapping-survey timing rather than any real late-year surge in mouse activity, since the record shows nothing at all from January through March.
