I came across a roosting bat some years ago while climbing on Raven Crag, Langdale. I don't know what the route was but I remember I was leading a rising traverse, I went to put my fingers behind a flake crack and jumped when I saw this tiny face, no bigger than my thumbnail, blinking back at me. Luckily I was in a pretty stable position so didn't immediately fall off. The flat-ish face meant that at close range the bat's features looked remarkably humanoid, and it had this funny bemused expression on it. Given that I'd probably just woken it up, probably not surprising. I swear it made direct eye contact with me. We shared a sweet moment gazing at each other before I came to and moved off as quietly as I could, and warned my partner to avoid the spot. As I say, I have no idea what the route was, and no memory of the rest of the climb, but that image has stayed with me.
