Considered France's foremost expert on wildlife and wildlife regulations, Jérôme Pensu is an unstoppable advocate of its cause, to the extent that he has often been commissioned by the courts to appraise sensitive cases over the last thirty years. On the front line in collecting seized parrots or removing birds from oil spills in the 2000s, he is a tireless campaigner against the "recreational wildlife industry" and for the release into the wild or, failing that, the preservation in sanctuaries of wild animals that have fallen victim to trafficking.
