The Museum Bat Colony

Bats hanging in roof of museum.


The museum building provides a nursery roost for one of the largest colonies of soprano pipistrelle bats in the country. The female bats come into the museum in the Spring to roost and to produce and rear their young. Bats are unusual in that breeding pairs mate in the autumn but the young are not born until the summer. This is known as ‘delayed implantation’. The babies or ‘pups’ are born naked and blind but their fur soon appears and covers their bodies and their eyes are open within a few days. They depend on their mother for the first six weeks.

Last year, we carried out regular bat counts throughout the spring / summer season. Counting bats involves standing outside the roost for an hour after dusk and recording the numbers of individuals exiting the building in ten minute intervals. The bats return to our building following hibernation in early spring.
