I expect I'll mostly be in mammals, as you'd expect, but it looks like there's some good interesting discussions going on.
I live in Cornwall, and unsurprisingly, I have a lifelong obsession with bats. when I was little we used to walk the dogs in the evening and I'd be counting the bats all the way round.
we recently rescued an underweight male pipistrelle (he's in my avatar, looking a wee bit skinny) and as advised, tried re-releasing him in the evening. but he couldn't get airborne. he would crawl to the edge of my hand, flap his wings rather desparately, and drop. luckily my mum had a towel held out underneath to break his fall. when it became obvious he couldn't manage it, we kept him safe overnight, and took him to be looked after the following morning.
several weeks later we had the phonecall that he was up to weight and flying again, and ready to come home. so we had the wonderful experience of re-releasing him.
this encounter put me in contact with the local bat workers, and I'm in the process of starting training, therefore filling a lifelong dream. I always wanted to work with bats, but real life got in the way a bit, and full time work meant I didn't have the time. now I'm part time, I do have the time for voluntary work, and was actually looking into different options at around the time the bat turned up on the kitchen floor.
at the moment, most evenings when the weather is up to it, I'll be out somewhere or other in the area with my clicky box. I'm lucky that Cornwall is a very good area for bats. we have pretty much most of the species somewhere to be found.
I also love using the bat detector to listen to my pet rats. especially when they're being tickled. rat laughter is fantastic.
open to any questions, and looking forward to getting stuck in.
