What are bats up to November to January?

Throughout November bats increase the time spent in torpid states and begin hibernating as reliable insect food supplies disappear.  By doing this they save energy and can survive the winter without food.  It’s essential that torpid bats are not disturbed as they may be unable to replace the energy they use waking and warming.

In December and January bats are hibernating and will wake seldomly.  Some bats hibernate in trees and caves, others will use the cold parts of buildings.  Additionally, a small number of sites have been created or modified by the bat group to afford better roosting opportunities for hibernating bats.   Members of the group, who hold the appropriate Natural England licence, visit hibernation sites over the winter to record species and numbers.   These visits contribute to a national population monitoring programme and are used to determine successful approaches to creating and enhancing hibernacula.   However, visits must be carefully regulated and limited to minimise disturbance.

If you find a grounded bat or are concerned about a bat’s welfare, then please refer to the Bat Rescue tab above.
