Last year I had quite a few bat adventures. I (eventually) managed to see five different species of bats, but frequently struggled with not being able to distinguish the calls captured by my bat detector. I could tell it was a species that I didn’t have ticked off my list, but not which one. So this year, I decided I needed to learn more about bats to help me in my quest.
This week I attended a Bat Ecology course, hosted by Surrey Wildlife Trust and taught by a member of Surrey Bat Group.The course was fascinating. A particular highlight was getting to see some bats up close, as there were a few captive bats present (who can’t be released back to the wild as they can’t fly properly). I learnt a lot about the different species of bats, and how to distinguish between them if I get a good view of them (when they’re not flying about in the dark). I was also reassured to learn that it’s not just me being rubbish at interpreting the sounds from my bat detector – even experts can’t tell distinguish between the Myotis bat species (Daubenton’s, Bandt’s, Whiskered, Alcathoe, Natterer’s, and Bechstein’s) using just a basic detector like mine.
So, having been reassured that it’s not (just) my incompetence that’s stopped me being able to identify some of the bats I’ve come across, I need to come up with a new way of seeing those species that I haven’t yet ticked off my list. I think I may need to start volunteering on some bat surveys.
But that’s not going to stop me walking around at night waving my bat detector in the air. Surrey’s a great place to see bats, as most of the 17-18 (it’s complicated!) British bat species are resident here. And using a detector to eavesdrop their hunting is a good way of getting a glimpse into their night time audio world, so different from our own.
