The hunters say they found the bird lying on the ground Saturday morning in Delaware Township, about 70 miles northwest of Pittsburgh.
The Pennsylvania Game Commission gave the hunters permission to capture the bird and it was taken to the Tamarack Wildlife Rehabilitation and Education Center in Saegertown.
The Sharon Herald reports the bird died Monday. A necropsy is planned Tuesday, but officials expect to confirm the bird died of lead poisoning.
Bald eagles can be poisoned by eating the carcasses of animals that have been shot with lead ammunition.
Game officials say hunters should bury animal parts they leave in the woods to prevent eagles from eating the tainted meat.
