Most birds of prey, such as eagles, hawks, ravens and gulls, get lead poisoning through leftover gut piles, un-retrieved carcasses and varmint carcasses left in the field. Birds of prey, also known as Raptors, and scavengers will ingest lead ammunition fragments left in the tissue of carcasses. They can also ingest lead tackle left behind in fish.
If not treated by professional veterinarians or licensed rehabilitators, these birds will die a slow death. Depending on the level of toxicity, lead poisoning could take weeks for a bird to succumb to the effects. Symptoms include weakness, emaciation, and un-coordination. They can not fly or even walk. Because of this, these birds are found along roadsides scavenging off of roadkill and are then hit by cars.
