Norway rats are commensal rodents that live wherever people do, not wild habitat specialists, so their New Mexico records cluster around developed sites inside otherwise wild-sounding places: White Sands National Park’s visitor facilities, Lincoln National Forest’s campgrounds and cabins, Oliver Lee Memorial State Park’s picnic grounds.
Only 25 records exist for the state, split between iNaturalist (6) and GBIF (22), placing the species in the rare bucket for New Mexico mammals (15th percentile, rank 151). Sightings are scattered thin across ten of twelve months with no real high month, more a sign of how seldom this nocturnal rodent gets photographed than of true absence elsewhere.
NatureServe doesn’t rank Norway rats in New Mexico at all (SNA, Not Applicable) because the species is classified as exotic here. It arrived with European ships centuries ago and now lives almost entirely around human structures, not truly wild landscapes.
