In reply to Darron:
This makes no real difference and I've no idea whether you're a bat expert or not, but I'm sure I remember someone who knew a lot about this posting quite recently that there were many tiny bat species in the UK and that not all that we might assume are pipistrelles actually are. And IIRC that some were only identifiable in the hand.
I made/make exactly the same assumption with one I saw hunting in daylight earlier this year (and with the ones I see by streetlight down my road) but I've no idea whether they actually are/were pipistrelles.
I've also got no idea how you tell the various species apart but I'm damn sure it's not as easy as IDing the local blackbird 😁
