Joshua,
Here is a link about the bats in Austin. BCI calls them mexican freetails. I am as confused as ever
about the difference but have read the mexican is a subspecies of the Brazilian bats. I have read that some folks in Florida call them Brazilian and they do not migrate. The mexican freetails do migrate and
many live in caves in great numbers. The Brazilian bats live in buildings and bat houses on the East coast.
Anyway it makes little difference to me because I can't tell one from the other. I do believe after
doing some reading that mine are Brazilians. I think I have improperly called them mexican freetails. They are here in small numbers and don't migrate. If you look at some of my previous posts, I took a photo of some this winter around January or February on a warm streak that we had here. Few on this forum know all there is to know about bats as they are always surprising us. I was really shocked a couple of years ago to see these freetails in with the little browns in my bat houses as they are not that common in my area of N.W. GA. I was glad to give you a reply and happy to see someone else interested in helping the bats.
Post your bat photos on the forum as it would be interesting to see them.
