That makes a lot of sense. I never thought about the hybernation angle before, just figured they would fly to a different location if something disturbed them.
I live in Maryland, we have bats everywhere. One flew in my house last week. Our development is 20 yers old an the bats have found lots of trees and caves nearby to roost in. I guess I think of them as being a tougher species than they really are.
Not to mention the two moonbats you have in the Senate...
