Rob, re Bats. I'm sure Jo and Simon would welcome your input. I found a Pipistrelle sp. and Noctule over the park a couple of years ago using my Magenta Bat Mk11b (which is not exactly accurate - it has difficulty distinguishing between bats and whales) so if you can add more species that would be very exciting. Would you be able to do a bat event in the park perhaps? I would certainly be up for that.
