The nest of the bald eagle is larger than any other nest in North America. This is because it is used again and again, and every year more is added to the nest until it may soon become as large as deep, across and weigh 1 tonne. One nest in Florida was found to be deep, across, and to weigh . The nest is built out of branches, usually in large trees near water. If there are no trees, the bald eagle will make its nest on the ground. Eagles have between one and three eggs per year. Both the male and female take turns incubating the eggs. The other parent will hunt for food or look for more to add onto the nest. The eggs are about long.
