The one bird that Eagles fear is the Great Horned Owl. GHOs have been known to run Bald Eagles off their nests. A realistic GHO decoy (one with a moving head) that you move from day-to day, may help until you get covered runs built. Look at the "Prowler Owl" or 'Rotating Owl" or even the inflatable one. A couple of them rotated out and around and moved may work for awhile.
