Le Chevalier Errant is a migratory bird species that travels the world from Polynesia to Alaska. It is the subject of the Kivi Kuaka scientific program, which studies the way birds anticipate natural disasters. Adapting, negotiating with reality: a faculty inherent to animal species also at the heart of the artistic approach of the two artists presented. The trust they place in chance unfolds like a neo-Darwinian vision of creation.
