Mexican free-tailed bats carry a NatureServe S3 vulnerable rank in Alabama, and the record leans toward GBIF (85 records) over iNaturalist (38), suggesting survey and roost-monitoring data document this colonial, cave-and-bridge-roosting bat more consistently than casual sightings. Conecuh National Forest’s single logged sighting sits at the edge of this species’ better-known range farther south and west across the Gulf Coast.

Records stay thin and scattered across eleven separate months with no strong single peak, February’s 5 sightings the closest thing to a high point, and November showing zero records, a pattern that fits a species whose enormous roost colonies are concentrated at just a handful of known sites rather than spread evenly across the state.
