Seen quite a few Bats around during the past few weeks, the first sighting coming on the 11th March and seen virtually everytime i've visited the lake at dusk
I believe they are probably Pipistrelle. I've bought a Bat detector so hope to get some positive ID's soon.
Also bought a couple of the Schwegler woodcrete bat boxes, so it's be interesting to hear from others who've used these boxes
