First, most hunters follow the rules of hunter safety but some are ignorant. A lot of eagles are killed by hunters who kill them to sell their feathers and talons on the black market. Next, tons of bald eagles are killed from being electrocuted. Their wings can sometimes get caught in the power lines. A lot of them also can get lead poisoning. They get it from eating deer or other animals that have already been shot. Younger eagles usually eat more roadkill or animals that have already died. They usually end up eating poisoned meat that are used as bait. Some die from being hit by cars. They can also starve to death, because they don't have enough hunting skills yet. They can also die from falling into the water.
