Just a few more Bat Facts: - Bats are nocturnal. - There are 17 species of bat living in the UK including the Common Pipistrelle (Pipistrellus pipistrellus) - Contrary to popular belief bats are not blind, they can see as well as humans but to locate their food they use echolocation. - Bats can live up to 30 years. - Bats don't build nests they creep into nooks and crannies, including the shadowy rafters of old buildings.
