Nests built on the ground or nearly level branches are disk-shaped. Bowl-shaped nests may occur where the tree trunk branches suddenly into several smaller, upright branches. The four shapes of an eagle's nest are cylindrical, bowl, inverted cone, and disk. The nests may be built in a tree, on a cliff, or even on the ground if there are no other options available. The eagle is very calm, except for when people try to hurt it or its family.
Scientists now put a colored number tag and a radio transmitter on each bald eagle they capture.
The scientists say this will help them keep track of eagles' behavior. A bald eagle eats 4 to 6 fish a day, usually in the early morning or late afternoon when there's a great amount of fish. Other foods the eagle eats are jackrabbits, ducks, waterfowl, and carrion. Baby eagles find their own food with no help from an adult because they have to learn to survive on their own. Life Cycle and Young As soon as a bald eagle reaches sexual maturity, about four or five years of age, the eagle concentrates on finding a mate and raising offspring.
