The Grey Long-eared Bat is a very rare bat that can only be found in the south of England because it is warmer there. It can’t tolerate cold winters. It can be seen in mature gardens and in small villages. It has long grey ears nearly the same length as its body and this is why it has the name the 'Grey Long-eared Bat’. It is related to the Brown Long-eared Bat.

The Grey Long-eared Bat has a very dark face, especially between the eyes which makes it look like it is wearing a ‘highwayman’s mask’. It has long light brown fur on top and grey-white fur below. Its wings are grey-brown and quite broad. This bat is a slow and fluttery flier that sometimes likes to hover.

In summer Grey Long-eared Bats roost in old houses with large attics and large roof spaces. When they roost, they curl their ears back or tuck them underneath their wings, leaving only the tips of their ears visible. Brown Long-eared Bats roost in small groups of up to twenty. They leave their roost about an hour after sunset and hunt for most of the night.  In winter they hibernate in caves, mines and cellars.
