Bald Eagle Haliaetus leucocephalus
About a month or so ago I was able to count at least six Great Blue Heron nests in this group of trees. This group of trees have been the home for a pair of Bald Eagles, as long as I can remember.. Now why would Great Blue Herons want to build their nests in the same tree as a Bald Eagle! The answer is protection.; The eggs and young of the Great Blue Herons are subject to a whole group of predators, including snakes, owls, raccoons, hawks, and other eagles. These Bald Eagles, being territorial, will keep these predators at bay. The price, however, is that the resident Bald Eagles do prey on the eggs and young of their so called guest.
There are eggs in the nest but the eaglets, probably hatched, are still not visible.
