Bald Eagles feed mainly on fish, either self-caught or taken from Osperys. But when fish are scarce they prey on smaller mammals like hares, muskrats and beavers. They will also take waterfowl and can be seen forcing ducks and coots to dive again and again until the exhausted bird is easily captured. However in winter when the waters freeze the Bald Eagles that remain in the Columbia Valley rely largely on carrion.
