At the start of the autumn many birds migrate over long distances, primarily from temperate areas to the south, before returning north during the spring. Through its geography and varied climate, France is a crucial stage for millions of them. Why do some species migrate and not others? How do the birds prepare themselves? How do they know where they are going? What are their strategies? Whereas these species are increasingly threatened by hunters, pollution and global warming, Christian Moullec, the man who flies alongside migratory birds in a ULM, and Xavier Muller, a scientific journalist, conduct the enquiry and meet the ecologists involved in working to protect them.
