Big brown bats carry a NatureServe S4 apparently secure rank in Arkansas, and 58 of the state’s 59 records are iNaturalist observations, so casual sightings document most of what’s known about this building-roosting bat here. Ozark National Forest, with 2 records, is the top named site.
June leads with 12 of the 59 records, about a fifth of the year’s total, tracking the maternity-colony season, with a smaller rise in September, while records fall to just 1 in both January and December, consistent with reduced winter activity as the species enters periods of torpor.
