Bald Eagle In Flight - Attacks Another Eagle on Ground

This was shot next to casino. I noticed the one Bald Eagle in the river and two others in the air. I tracked the one adult and there's a glimpse of a second Bald Eagle in the air. The one that I track circles and spars with the Bald Eagle in the river. The flying Bald Eagle hit the other twice. In another video, it comes back and the two spend time in the river.
