Marine, It is an Immature Bald Eagle, they don't get the white head and tail until around 4 or 5 years old, there is a large nest a couple of miles from this site that has been used for many years, most of the time on our trips on the river ice you may see one in the nest, its large. If we make a trip on the river this year, depending on the ice I will try to get a picture of the nest and post it. Bald Eagles will feed on carrion, matter of fact that is where a lot of them get killed feeding on road kill.
