Serotine bat

Serotine bats are one of the largest British species, and one of the first to emerge in the evening. Serotines inhabit almost all of Europe and parts of Asia, but in the UK are restricted to southern England. They have a relatively slow, looping flight and in the summer, roost in tree hollows and attics. In the winter, they hibernate in tree hollows, caves, old mines and cellars. In Europe, the females give birth to one young, but in Asia, they typically have two and occasionally three.
