Subadults (only 1 year old) come back later; they may not even start the return migration north until late April. Golden eaglets usually hatch in mid to late May or early June. When the chicks are about 70 -75 days (not quite 2 1/2 months) old they are ready to start learning to fly. They fledgings (eaglets learning to fly) remain in their natal areas (the area where they were born, their nest area) for four to eight weeks after fledging. During this time, they are dependent upon their parents for food and protection from predators and they spend most of their time exercising their muscles and learning to fly. They learn to fly independent of each other and their parents. In late September or early October, when the eaglets are about 4 months old, they leave their natal areas and begin their southward migration completely independent of their parents. The success
