That this is a white-tailed eagle is easy to see from the powerful beak and the short tail feathers. The yellow colour of the beak, the greyish-brown of the plumage and the pure white tail disclose that this is an elderly individual.
As indicated by this display, the white-tailed eagle is a carrion eater. The carcass is that of a roe deer, but it has not been felled by the eagle. Roe deer sometimes succumb to starvation and illness, especially during the winter.
The white-tailed eagle also eats fish such as bream and pike, and waterfowl such as eider ducks and mergansers. It hunts these pray itself, sometimes exhausting them with lengthy pursuits.
