Key information

Pipistrelles are tiny bats with reddish-brown coats and blackish-brown ears, nose and wing membranes. They are common throughout Britain. Like other bats, pipistrelles are nocturnal. They emerge at dusk to feed for a couple of hours before returning to their roosts.

In the winter they hibernate in trees and buildings. In the summer they use trees, buildings and bat boxes to roost. Pipistrelles are agile, fast fliers.

During the breeding season males defend a territory, Females visit these territories and after mating give birth in June and July, usually to a single baby. Bats are mammals and feed their young milk. After about three or four weeks the young bats are able to fly and leave the roosts in August.

IMPORTANT: If you find a sick or ailing bat, you should not approach or handle the animal but seek advice from the Bat Conservation Trust.
