The complete county distribution, spread across 46 Kentucky counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Eastern red bats have 82 Kentucky records, with distinct peaks in April, August, and October. That spring-to-fall pattern fits a tree-roosting bat documented along wooded river corridors and greenways, while survey timing and accessible flight paths shape the map.

Kentucky treats the species as native, and the current monthly series has no January records. Its tie at twenty-sixth in the record ranking describes reported encounters only; it doesn’t indicate that red bats are absent from quiet areas or quantify their statewide abundance.
