Nest snags must be sturdy to support nests. Nest trees should have an open form and sturdy branches in the upper one-third of the tree. Eagles nest in the overstory. Roosting sites need not be as near to water as nesting sites. It is more important that roosting sites are in dense stands of old growth that offer protection from weather.
Eagles usually arrive at roost sites after dark and depart roost sites before dawn.
Bald eagles eat fish, reptiles, birds, mammals, invertebrates and carrion, including that of livestock. They are most easily disturbed by pedestrian traffic and least disturbed by aircraft.
