Eagle/Peregrine Territories

It seems in the latest Catalina update (3-25-17) that Peregrine Falcon are establishing more territories on Catalina. In a previous update, I took it they may have also contributed to the TH eagle pair moving nest locations. It seems the two species do not co-exist in the same territories, but can you clarify that and also give a little info on the differences in territories that each species requires (space, location due to food, etc.). Also, will the two species eventually reach a balance that precludes one species from negatively impacting the other? Thank you!

Both species prefer the coastline area on the islands, but peregrines nest in caves/potholes/ledges and the eagles either on exposed pinnacles or trees. The eagles feed mostly on fish, with some marine birds. The peregrines are almost exclusively bird-eaters, both marine and terrestrial. Because peregrines are smaller and more agile, they will harass the eagles, but the eagles could take peregrine chicks. They seem to space themselves so as to minimize interactions, but as the populations grow and the available space decreases, there could be more conflicts as they try to create a territory.
