About

The brown long-eared bat is a medium sized bat with huge ears. As with all UK bats, they are nocturnal, only coming out at night to feed on midges, moths and other flying insects. They have an incredible sense of direction thanks to echolocation, which they use to hunt prey. Brown long-eared bats roost in holes in trees and old buildings, and feed in parks, gardens and woodland. In the summer, females form maternity colonies and have just a single pup each. They hibernate over winter between November and April.

How to identify

The brown long-eared bat has greyish-brown fur and characteristically big ears, nearly as long as its body. It has a relatively slow, fluttery flight.

Did you know?

The brown long-eared bat is known as the 'whispering bat', because its voice is very quiet - no need to shout when you have such big ears! While at rest, it tends to either curl its ears back or tuck them under its wings.
