Evening bats show one of the starker source imbalances in this Alabama rank tier: 132 GBIF records against just 15 from iNaturalist, nearly nine to one, meaning specimen and roost-survey data, not casual sightings, document most of what’s known about this small colonial bat in the state. NatureServe rates the population S5, secure, fitting a species that’s widespread across the Gulf Coast’s bottomland forests.

The handful of iNaturalist-visible records cluster from May through September with a June peak (4 sightings), tracking the maternity-colony season, though with GBIF dominating the total record so heavily, that pattern likely says more about when casual observers happened to encounter one than about the bat’s actual seasonal activity.
