Mexican free-tailed bats carry a NatureServe S5 secure rank in Mississippi, and the record leans toward iNaturalist (36 of 42 records) over GBIF, suggesting casual sightings, not survey data, document most of what’s known about this fast-flying, colonial bat in the state.

January and March together account for 21 of the year’s monthly-tallied sightings, exactly half the total, an unusual winter-leaning pattern for a species better known farther south and west for massive summer emergence flights; Mississippi likely sees this bat as a wintering or passage visitor from larger colonies rather than hosting maternity roosts of its own.
