  3. Bechstein's Bat


Found almost exclusively in woodland, Bechstein's Bat is one of our rarest bats. Like all British bats they are nocturnal, feeding on midges, moths and other flying insects which they find in the dark by using echolocation. Bechstein's Bats hibernate over the winter. Mating occurs in autumn and spring, with maternity colonies forming in April and May. Females gather in colonies of between 10 and 30 bats, but can number up to 100 in some cases. Babies are born in June and July.

How to identify

Bechstein's Bats have pink faces, long ears which are clearly separated at the forehead, reddish-brown fur on their back and pale-grey fur underneath.

Where to find it

Very rare, found in southern Wales and parts of southern England.

How can people help

Bechstein's Bats are very rare due to the extensive loss of our woodland habitats. Pesticide-use has also reduced their insect-prey. 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.
