Like all species of bat in Britain, the Natterer's bat is less common than it used to be. The reason for its decline is that its food and shelter has been seriously threatened by modern farming practices and destruction of natural habitats.

Hibernation

Like all British bats, Natterer's bat hibernates during the winter, when there is a shortage of insects. In December the bats look for a cool spot around the entrances to caves, but if they cannot find a suitable cave, a hollow tree or similar site is used. They may wake up from time to time during hibernation but do not emerge until early March.
