Tennessee’s evening bat overlay lists 13 iNaturalist records and 64 GBIF records from 2000–2026. Within the dated monthly series, June leads with six entries, followed by July with four and August with three; database totals and monthly records document submissions, not bat abundance.

Reelfoot Lake State Park is the only top place recorded in the overlay, with one entry, while Hatchie and Tennessee national wildlife refuges are also suggested search areas. The summer cluster is useful for describing this dataset, but sparse counts in the other months prevent a firm statewide activity conclusion.
