This beautiful video from Auvergne, France shows people flying with birds.
Since 1995 Christian Moullec has been working with geese and cranes, pioneering ultralight flights with them and assisting rare birds on migration.
His company, Voler Avec Les Oiseaux, now offers ultralight flights to the public with his own small flocks of birds.
