If I made a film about pigeons, it was for ethological reasons. I had noticed in the square near the Conservatoire National des Arts et Métiers that there were often one or two pigeons from outside the neighborhood that kept their distance from the locals, did not take part in their food, and two or three days later had left or accepted. I wanted to film this behavior and show it to kids to find out what they thought about it...and then it changed. I became interested in these birds... The film begins with a tribute to the animal photographer Ylla and ends with a tribute to Étienne-Jules Marey, creator of scientific cinema.
