Bat Sound Library
Access the Bat Sound Library (password required)
BCT has created an online bat sound library which features bat calls recorded from tuneable heterodyne detectors. It is an ongoing project which aims to provide recordings of all UK bat species, illustrating the differences and similarities between different species' calls and how they vary in different habitats.
This resource is exclusively for BCT Members and National Bat Monitoring Programe (NBMP) volunteers. If you fall into one of these categories then BCT will send you your user name and password. If you haven't received these yet then please contact Philip Briggs at email@example.com or on 020 7820 7179.
