Northern hoary bat has only 19 recorded sightings in Michigan, all from iNaturalist, clustered loosely around Hiawatha National Forest, Ottawa National Forest, and Seney National Wildlife Refuge in the Upper Peninsula. As Canada’s smaller, boreal-adapted counterpart to the widespread hoary bat, it roosts solitary in conifer foliage, a habit that keeps it out of the colony counts other bats show up in.
With records this sparse, spread thinly across May, June, September, and November, the state doesn’t yet have enough data to describe a real seasonal pattern, which is why this overlay flags timing as unresolved rather than guessing at a peak. NatureServe ranks the species S5, Secure, in Michigan even though its global G3 rank runs lower.
