Something odd happened to me last night. I had taken a break from working and was sitting on my screened-in porch reading “The Amber Spyglass” (the third book in the “His Dark Materials” trilogy upon which the new “The Golden Compass” movie is based). This was about three in the morning. Anyway… As I was reading the book I heard something pretty heavy fly into the window about six feet away from me. I looked up and saw what looked like a large bat clinging to the screen outside. I got up to walk over to it, to get a better look, and it dropped off the screen as I got closer. I looked around a bit, through the window, but didn’t see anything, so I sat back down with my book. A few minutes later I heard the “bat” flapping around down by the bushes under the window, and beating its wings against the outside porch wall. I heard a high-pitched squeak, so I was pretty sure it was a bat at this point. It was moving along the wall towards the corner of the house away from me, as it kept beating its wings against the wall. It turned the corner, where the front door is, and kept beating and moving until it was beating on the front door and screeching. This bat seemed to be trying to get into the house – onto the porch I was reading on. It was the oddest thing. It beat on the front door for a good four or five minutes. I thought maybe it was confused somehow, by the lights – I had no idea – so I turned the porch light off and went to get a flashlight. When I got back the bat wasn’t making any more noise. I went outside with the flashlight and looked around, but saw nothing. I turned the porch light back on, and went back to finish my book, and it never came back. I think it was a bat. Is this odd behavior for bats? I recently moved to a new house, and where I used to live, you really wouldn't see bats any larger than palm-sized fruit bats, so I have little experience with them.
