Do bald eagles leave their parents?

Young bald eagles typically shed their down feathers and grow primary feathers around 10 - 12 weeks after hatching. It is around this time that they will attempt their first flight. Those that survive (about 40% don't) will hang around the nest for another four to five weeks while their primary feathers continue to grow and strengthen. Therefore, a bald eagle will leave the next permanently around 14 - 17 weeks after hatching.
