Tristan is a bird educator, he prepares birds for theatre and cinema and develops their positive contact with humans in “ornitotherapy”. As a child, in the forest behind his parent’s house he realized that, while remaining still for a long time, the animals came out of the vegetation. The approach in respect of the rhythm of the other, remains the basis of Tristan’s method. His technique is based on the understanding of bird’s sensibility, that is more extensive than ours, moving to areas we have partly forgotten in the course of evolution. Body position, intensity of the look or even the intentions that animate us, have for birds a great deal of importance. Following Tristan, we can enter their world made of minimal, subtle and incorporeal events.
