To my surprise, I opened the back door and found a bat laying on the doormat. It appeared injured and was kind of flopping around. Eventually it crawled across the lawn and up our rock retaining wall and nestled in between two rocks. I called animal rescue and they said bats could not fly unless they were around 15 feet above ground(didn't know that.) They suggested I put on leather gloves and put it in a tree. Well, thats what I did. It hung out there most of the day, and I checked an hour ago and it was gone. Hopefully it made it out OK. Another fact I did not know is that they can eat around 1200 insects an hour. So I hope he hangs around. He did hiss at me and show his teeth while I was handling him.
