Pipistrelle bat

A few static shots of a common pipistrelle bat (Pipistrellus pipistrellus). I would like to try some flight shots but don’t have a working IR trigger which I reckon would be required for such a small and active mammal. Many years ago, in the days of film, I tried photographing bats in flight with an home made IR trigger but with little success. There was no way of shooting and checking the set-up and re-adjusting as necessary until the roll of transparencies had come back from the lab days later. Now, of course, with digital it would be instant feed back. I might have to dig around in the attic to see if I still have the trigger!
