Western harvest mice post the largest record count of any species in this Nebraska rank tier by far, 1,116 sightings, yet only 5 come from iNaturalist, an overwhelming GBIF specimen and trapping-survey signature rather than casual photography. NatureServe rates the state population S5, secure, fitting a species that’s genuinely widespread across Nebraska’s grasslands but rarely seen given its tiny size and nocturnal habits.
Records peak sharply in June (229 of the year’s monthly-tallied sightings) with a secondary spike in November (182), a two-peak pattern that likely tracks survey timing and possibly a fall population bump before winter rather than the mouse’s own visibility, since a dataset this GBIF-dominated says little about when people actually encounter the animal.
