Trilobite

We have a hibernating bat in our hallway. At first we thought it was dead, and possibly trapped in some insulation foam. I climbed up on a ladder to remove the body and when I touched it, the little guy sleepily lifted his head and glared at me! I think he’s a little brown bat (Myotis lucifugus), or possibly a big brown bat (Eptesicus fuscus). I hope he has a relaxing winter.
