Deer mice are one of the most widespread native rodents in North America, and Indiana’s 17 records scatter across a dozen counties, from Indiana Dunes National Park and LaGrange County in the north to Lawrence and Decatur in the south, wherever fields and brush give this mouse ground to forage across at night while staying hidden from hawks and owls by day. All of them are research-grade iNaturalist observations, 10 also held in GBIF, a thin file for a small nocturnal mouse rarely caught on camera.
Records peak modestly in March and April and scatter thinly through the rest of the year, too few to show a firm seasonal pattern, and deer mice stay active through Indiana’s cold months rather than hibernating. NatureServe rates the species secure (S5) statewide.
