While bald eagles have no natural predators, they are at high risk from human activity such as chemical pollution, habitat destruction and hunting. The mortality rate for juvenile bald eagles is just over 50 percent in their first year of life and falls to around 25 percent after that.
Bald eagles are at risk of death from DDT poisoning used in Mexico that passes over the border into the United States by wind. Eagles are also at risk of lead poisoning from bullets and other poison in dead animals they eat. Other risks to the bald eagle population includes electrocution from power lines, accidental and deliberate hunting, and human development that destroys their hunting and living habitats.
