Hi I am newbie and just popped in to say hello, and to let you know that I have 3 bats that seem to regually visit my garden, I think they are the common pipistrelle bat, as I have managed to get a bat detector and they come in at about 55 Khz, but saying that last night as two flew off together the noise changed to like a shrill sound so don't know what that was about, anyway hello.
