Biologist and film-maker M. Terrasse has been working for over 35 years to return vultures to their natural habitat in the Cévennes, a project that won him a Rolex Award in 1984.
Patrick Chiron, of the League for the Protection of Birds (LPO), collects dead animals from farmers of the region to supply vultures' open-air feeding sites.
M. Terrasse hides from the clear-sighted vultures to film them at their open-air feeding site. The French biologist has 22 wildlife documentaries to his credit, mostly about birds.
