Secret migrations

In the four episodes that make up this series, we travel the world alongside migratory animals of exceptional endurance.

Sometimes weighing just a few grams, sometimes even less, and totally inexperienced, our migratory animals don't hesitate to embark on veritable odysseys.

In the company of the best specialists on each species, we will discover the surprising journeys of these migratory birds, the routes they take, and lift the veil on some of the astonishing features of their migrations. Today's miniaturized transmitters, satellite tracking and DNA analysis reveal unsuspected behaviors that are essential to the survival of these little-known migratory birds.

With "Secret Migrations", we discover the extraordinary journeys of these extraordinary animals.
