LISTEN TO THE BAT

Introduction

The barbastelle is a medium sized bat, with a distinctive, pug-shaped nose. The ears are broad, joined across its head by skin, and covered in a ginger-brown fur on the rear surface. The tragus is triangular – broad at the base but with a nearly parallel tip which starts about half-way along its length. The barbastelle is predominantly a woodland species, but it will also forage over a range of other habitats including wet meadows and streams.
