The eagle's light wight is due to the fact that the bird has hollow bones. The lightness of the bird accounts for the the smallness of it's prey. The eagles nest in trees and usually hatch two to three eggs a year. The gestation period is about 35 days. The baby eagles can fly about three months after they are hatched and they leave the nest shortly thereafter.
Eagles often follow sea birds in order to catch their fish prey.
Eagles will also eat other already dead animals. Interestingly, the bald eagle has very few enemies. The eagle's main predator is man. River pollution is a main cause of the decline in the population of the bald eagle. Often, the eagle's habitat is ruined due to human development.
