Grey long-eared bat
As their name suggests, long-eared bats have strikingly large ears, which are three quarters the length of the head and body. When resting, the ears are folded and held backwards.
The maximum recorded age is 14 years.
Body length: 4-5.8cm, Wingspan: 25-30cm, Weight: 7-14g.
Grey long-eared bats are very similar in appearance to brown long-eared bats except for the colour difference. The ears, face and wing membranes are dark grey-black.
They range across central and southern Europe. In the UK, grey long-eared bats are restricted to the far south, and are one of the UK's rarest mammals.
They prefer cultivated land and are usually associated with areas near to human settlement.
Grey long-eared bats emerge to feed after dark, hunting moths, flies and beetles. They are skilful fliers and use their large ears to listen out for prey.
In the summer, grey long-eared bats roost in buildings, and in the winter they hibernate in caves, mines and cellars. They hibernate from October to March, usually solitarily.
Little is known about the reproductive behaviour of grey long-eared bats, but they are thought to give birth to one young in mid-June.
Grey long-eared bats are not listed by the 2000 IUCN Red List.
