Through a container for birds (knobs, hollowed-out boxes, cages) one can glimpse the orni-culture in San Miguel del Padrón, Havana, Cuba. The coming and going of breeders, sellers and curious people is a sample of a local collaborative process, of a system of exchange relations + citizen initiative. It is an extensive network of practices and practitioners, organized outside of institutions and united by the passion (passion for trills, for flight).
