Life History of the Bald Eagle
Bald eagles are predominantly fish eaters, which is why they build their nests and live near water and why they migrate to open water areas like the Upper Delaware region in the winter.
However, when times are tough, they are very opportunistic and will eat birds, small mammals and carrion (dead animals).
Bald eagles normally mate for life, but will secure other mates if one is lost.
Females lay 1-3 eggs and incubate them for 35 days.
Migratory immatures often return to the general vicinity (within 200 miles) of birth when they reach maturity and are ready to find a mate and build a nest.
