Peggy ‘bat sniffer’

Peggy is our professional sniffer dog. She has the important task of searching for bird and bat carcasses near wind turbine sites as part of post-construction monitoring. Unfortunately, some birds and bats collide with the turbines, but with the help of Peggy, we are trying to do our bit to understand the impact turbines may have upon these populations.

Peggy has poor IT skills and consequently is not on LinkedIn, although she features regularly on our Social Media with the help of our Marketing Officer Ashley. In her spare time, Peggy can often be seen enjoying the surf on various South Wales beaches.
