  3. Whiskered bat


This small bat is very similar to a Brandt’s bat, in fact these bats were only separated into two species in 1970. The whiskered bats emerge from their roost sites soon after sunset to forage on moths and other small insects. 

How to identify

A small bat with shaggy, dark grey or brown fur with golden tips on the back and grey on the belly. Their flight is fast and fluttering and they forage over water and in woodland. They will fly often along hedgerows and woodland edges.

Where to find it

A rare species which may potentially be found throughout England and Wales but particularly in the north and west. They roost in older buildings and some hibernate in caves and tunnels but it’s not known where the majority overwinter.

How can people help

Decline in woodland and modern agricultural practices threaten these bats. They are also threatened by disturbance to hibernation sites. The Wildlife Trusts are working hard to restore our native woodlands and you can help our bats in your own garden, too, by putting up a bat box. Pick a tree that gets some sun during the day, but is near to a hedge or other trees. All UK bats and their roosts are protected by law, which means it is illegal to harm or disturb them.
