Eagles and other scavengers ingest lead when they feed on the remains of animals killed with lead ammunition. But theyre also expert fishers, theyre better fishers than bald eagles are. area, nationwide have chronic lead poisoning, study finds Large-scale report found nearly half of 1,200 golden and bald eagles suffered from repeated lead exposure By Dana.
