Last week I went into the large roof space of a house near Alnwick and came across this huddled group of day-time roosting Brown Long-eared Bats. If you carefully count the ears there are six individuals here and they didn't react at all to the camera's close presence or even to the flash. There were two other individuals flitting about.
I've seen occasional individuals before in flight, but never come across them roosting. Really quite exciting, even though the species isn't uncommon according to the Northumbrian Mammal book published last year.
