Silver-haired bats carry no NatureServe state rank in Arkansas, SNR unranked, and the record leans toward GBIF (10 of 14 records) over iNaturalist, with Ouachita National Forest’s 3 logged sightings anchoring the top named site for this solitary, tree-roosting bat.

October alone accounts for 4 of the 14 records, close to a third of the total, fitting the fall passage window when one of North America’s most migratory bats moves south through Arkansas; the record goes silent from May through July, consistent with the bat spending the breeding season farther north or elsewhere.
