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.
If one of the pair dies, the surviving bald eagle will look for a new mate in the next breeding season. The nests are built on the tops of trees. The pair uses sticks and twigs to construct a platform nest. Some pairs return to the same nest the following year.
