Vogelmenschen plot
This making of of the spectacular nature documentary “Winged Migration” (2001, Jacques Perrin) shows how twenty people sacrificed four years of their lives to raise the migratory birds that are followed in the documentary in their flight. The recording technique was unique: a light motorized glider with a camera flew with the birds so that the viewer sees the world from the birds' point of view. To familiarize the birds with the aircraft and the people, they are surrounded by human sound from the first moment they can hear - still in the egg.
