Saga of the White-tailed Eagle – The Secrets of Nature
The sea eagle was once widespread throughout almost all of Europe and graced the coats of arms of many different countries. During the 19th and 20th centuries it was driven to the brink of extinction by hunting, the increased use of pesticides and the destruction of its habitat.
This touching animal drama recounts the true life story of one individual bird, observed over the course of a year. Beginning with its birth in a lowland forest in Central Europe the film team follows the eagle’s first outing with its brothers and sisters and subsequent distant migrations to places as far away as Scandinavia. Finally it chronicles its dramatic lead poisoning, recovery and resettlement in a nature reserve.
