Back garden Pipistrelle 45

Over the past few evenings I've been gazing out the kitchen window at dusk looking for my first bat of the season. On the 21/03/2010 (at 18:54 looking at last years field notes) I saw (and heard) my first Common Pipistrelle. Last night I looked out the back window and again saw the hundreds of Jackdaws swirling over Shenley Wood before they roost. At 18:40, bang on cue a bat flew over the house. I found one of my bat detectors and raced outside with the frequency set to 45. I then had to wait another 5 minutes before a Common Pipistrelle (45) did a few flybys over the back gardens and happily fed. I even got the girls to come out and have a look (and listen) to this marvellous mosquito muncher. Mammal number 5 and Bat seasons open!
