I have an Osprey nest behind my house. Once, a young bald eagle got into a fight with the Osprey which were sitting on eggs at the time. One Osprey stayed in the nest and the other fought in mid-air with the eagle, locking claws with each other. The eagle then flew off with the osprey right on it's tail. I kept checking the nest and it was 3 hours before the Osprey was back. I thought for sure he had lost the fight. Young eagles have checked out the nest site before, and once a pari of adults. The interloper was too young to be thinking about nesting.

Hi, My guess is that the Bald eagle was probably trying to steal the Great Blue Heron’s prey. Eagles are known to nest near GBH rookeries, as they prefer the same type of trees to build their nests on. I have heard of them preying on their chicks, but not an adult. There is a nesting pair of Bald Eagles at the Great Swamp NWR, but I’m not sure if this Bald Eagle was one of the pair. The Raptor Trust has reported just the other day, that a Bald Eagle has been visiting Uno, their resident Bald Eagle. Crazy, isn’t it?
