If there’s one thing Mark Avery knows (and before any wags start up, he knows far more than just one thing…) it’s how to talk to people about nature conservation. As a twenty-five year veteran of the RSPB, thirteen of those as the organization’s conservation director, Mark has quite likely spent more time communicating about the subject through his speaking, writing, and for all I know interpretive dance, than most anyone else I’ve yet met.
