This brown long-eared bat (Plecotus auritus) colony is occupying a hole made by grey squirrels (Sciurus carolinensis) that is also used by Natterer's bats (Myotis nattereri) and blue tits (Cyanistes caeruleus) | Bat Tree Habitat Key

Our pine marten project cameras get triggered by all sorts of visitors, including some very inquisitive bats! 🦇 Although the footage is fleeting, we think this little one is a brown long-eared bat. They’re named for a good reason, their ears are almost as long as their body. Also known as the “whispering bat”, this species has an incredibly quiet call. With ears like that, there’s no need to shout! Find out more 👉 https://buff.ly/czPcVs0 The Two Moors Pine Marten project uses cameras to monito

Grey Long-eared Bat - Back From The Brink

28 brown long-eared bats emerging from a squirrel-hole. The film is edited to show the bats emerging in quick sequence, but the actual emergence took 44 minutes with gaps of up to seven minutes between individual bats. The reason you can't hear the bats is that they didn't echolocate as they left; I had an Anabat Walkabout within 2 m of the entrance and it didn't record a single call... So, the message here is that without the camera, the emergence would have been entirely undetected. | Bat Tree
