North American deer mice carry no NatureServe state rank in New Jersey, SNR unranked, despite being one of the continent’s most widespread native rodents, a gap that likely reflects how easily this species gets confused with the more commonly documented white-footed mouse rather than any real data scarcity. All 11 records were logged on iNaturalist, and 8 of them also appear in GBIF, so the state’s record rests on photographs, unusual for a small nocturnal rodent that’s usually caught more often than photographed.
Records spread thin across seven separate months with a modest November peak (3 sightings), too uneven a pattern in a count this small to describe any real seasonal trend beyond confirming the species turns up sporadically across ten counties, from Bergen and Passaic in the north to Cape May in the south.
