This video is called Greenland White Tailed Sea Eagle.
Translated from Staatsbosbeheer in the Netherlands:
The sea eagle couple in the Oostvaardersplassen, a nature reserve of Staatsbosbeheer between Lelystad and Almere, this year have two eaglets in their eyrie. Rijkswaterstaat Waterdienst were counting birds from the air. After studying the photos it became clear that there were two chicks in the nest. This is the third year that white-tailed eagles are breeding in the Oostvaardersplassen. However, this is the first time that two eaglets have hatched.
