Eastern red bat records in Minnesota concentrate in the northwestern Red River Valley, at Agassiz and Tamarac national wildlife refuges and nearby wildlife management areas. As a solitary tree bat that roosts hanging in foliage rather than in colonies or buildings, it’s rarely caught in the hibernacula counts that dominate records for cave-roosting bats.

GBIF’s 65 records outnumber iNaturalist’s 32 roughly two to one, likely reflecting acoustic and mist-net survey data gathered across the bat’s long June-through-September reporting window. NatureServe has not assigned Minnesota’s population a subnational rank, though its global G3 rank signals real vulnerability across its full range.
