Jun 16, 2011. Decorah bald eaglets branching out, soon to fledge. Nearly four months after the bald eagle mother laid her three eggs, and about 10 weeks after those eggs were hatched, the world-famous eaglets of Decorah, Iowa, are behaving as though it's time for them to leave their 80-foot-high nest and begin life on their own terms.
Owls breed before eagles do, so they try to move in before the eagles get there. Great Horned Owls and mice also nest in the lower parts of a big nest made by eagles -- even when the eagles are using it! Because of their size, adult Bald Eagles have very few predators.ald eagles also have a long, heavy yellow bill which is curved for tearing prey. Young eagles are mostly dark. They do not get the white head and tail until they are full grown. Bald Eagles live near water, including lakes, rivers, marshes, bays, and oceans.
