The pairs usually return to the same nest site in January or February, year after year. Occasionally, they will build a new nest in a different tree within their territory. One to three eggs are laid in March and hatch 35 days later. Young eagles begin to fly 12 weeks after hatching, usually in July. Adult eagles continue to feed their young until the immature eagles learn to forage for themselves and disperse.
Eagles feed primarily on fish, which is why they live and nest along shorelines.
If other food sources become readily available, such as waterfowl or carrion, they will take advantage of the situation. Bald eagles often perch in a tree and rely on their keen eyesight to spot their prey. Although hunting from a perch requires less energy, eagles remain alert for a potential meal even when flying. Eagles fly with their wings spread straight out and do not hover. They fly with a bend in their wings and frequently hover.
