Eagles roost near the water in a big, twiggy nest built on top of the largest conifer they can find. More social than other birds of prey, Bald Eagles can sometimes be fond flying to communal roosts in the winter. It has no feathers on its feet, and females are bigger than males. Immature Eagles lack the golden eyes and white head and tail of their parents. These colors won't develop until the Eagle is between three and seven years old.
Eagles mate for life.
About one out of every four fledgling Eagles die, primarily of starvation. Pesticides, habitat loss and heavy metals have also hindered reproduction. Eagles are considered endangered in many parts of the United States.
