The photographer and bird lover Xavi Bou presents this project, born from the innocent and restless look at the sky when he was a child. The proposal makes visible the invisible movement of the flocks of birds in our skies. Bou claims their presence, even in the urban world. The photographer investigates and condenses their delicate movements and displays a fascinating complexity in a set of photographs. He thus offers us the possibility of studying and enjoying the marvellous patterns hidden in the collective movement of birds.
