* Predation: Eaglets and eggs can be preyed upon by other birds of prey, such as great horned owls and golden eagles. Adult bald eagles are typically not preyed upon, although they can be killed by larger predators, such as cougars and bears.
* Collisions: Bald eagles can collide with power lines, wind turbines, and other structures.
* Human activities: Bald eagles can be killed by humans through hunting, trapping, and habitat destruction.
