The staff did an amazing job of putting together a wonderful program including talks about bats and bat conservation and actually hiking in the woods at night. Live bats were brought by Leslie Sturges, a bat rehabilitator who works to release injured bats back into the wild.
And while this was a really fun evening, one of the key points was that many bats are dying from White Nose Syndrome (WNS), a fungus (Psuedogymnoascus destructans) that attacks them during hibernation and has in many places created population losses of more than 90 percent for some species.
Little Brown Bats (Myotis lucifugus) have been hit hard, and while they were one of the most common bats in the northeast ten years ago, they are now absent or very rare across the area. There is a site working to save them, run by Ms. Sturges, and they do accept donations. The campaign is called Save Lucy. Lucy being the common name among biologists for the species, Myotis lucifugus.

There is lots of info on this site. But I also recommend reading the Wikipedia site for WNS

And to see a map of the spread of the disease the Pennsylvania Game Commission has been a leader with this:
