Brown long-eared bat flying through oak leaves

Brown long-eared bat

Brown long-eared bats, as their name suggests, have strikingly large ears. These large appendages are three quarters the length of the bat's head and body. When resting, the bats fold their ears and hold them backwards. They have a slow and fluttering flight, often close to the ground, which makes them vulnerable to predation from domestic cats. In the summer, they roost in tree holes, bat and bird boxes and attics. In the winter, they hibernate in cellars, tunnels and caves, usually alone.
