Last year I had left the back door open one night to get a bit of cooler air into the house, plus give the dogs free access to outside when nature called them. I was sitting in a spare bedroom that I use for a computer room surfing the net when I thought I saw something whizz by the door. I put it off as my imagination, but then, it happened again...and then a third time. Can't be my imagination, I figured, probably some big old moth. I went looking to see what it was and get rid of it, and lo and behold, it was a little bat, maybe 6-7 inch wingspan.
I tried to shoo it out the back door, but the silly thing flew downstairs into the basement! So, down I go and finally get it to fly up the stairway and then it flew outside, since the stairway leads straight up to the back door. It's about the only bat I have ever seen around here, although others have seen several. The mosquitoes the little bugger ate more than made up for the little bit of effort it took to get him back outside and I was glad he made it unharmed...plus, it made for a nice story to tell my friends!
