The bald eagle is a large North American bird. Therefore, it has very few natural predators. However, the eggs and fledglings of these eagles are often predated by a number of animals and birds. Some of the predators that prey on the nestlings and eggs of bald eagles are raccoons, ravens, black bears, wolverine, bobcat, Black-billed Magpies, hawks, crows, gulls and owls. Arctic foxes usually attack the ground nests of these eagles. The baby bald eagles that stay on ground and are not yet ready to fledge are more vulnerable to mammals.
