We have three types of bats that we can recognise round here, but the local Rangers say there are actually twelve
We've been lucky and they don't seem to want to come into the houses, but then, we do have the trees right next to us.
It's surprising just how tiny they actually are, and how even tinier a space they need to get into.
The Rangers said that they mostly roost behind pieces of bark round here, and you really need to know what you are looking for to find them.
I admit I haven't gone looking, but I do watch them flittering along the tree line, around the blocks of houses, and back in a sort of flittery loop, and am quite happy they munch the moths.
My hearing is pretty bad, but I still hear the high tones easily and I can hear when the bats are about. I doubt I'm hearing all of their sounds but I do hear the high pitched chirps and burps. It's fascinating to hear them with the bat recording machine though. The Rangers can interpret them, and a kind of raspberry/gulp noise is apparantly them guzzling a moth
