The Centre Wildlife Care in Pennsylvania, which had been helping to rehabilitate the bald eagle, released the bird Thursday at Prince Gallitzin State Park in Cambria County.
The bald eagle can be seen in a video posted by the Centre Wildlife Care taking a minute to explore its surroundings before spreading its wings and flying away.
Once absorbed in the gastrointestinal tract, the lead becomes toxic. Lead poisoning can cause a lack of judgment and impaired ability to walk or fly, resulting in seizures, accidents and death.
Depending on the severity of the poisoning, some eagles survive after veterinarians use chelation therapy, injecting the birds with a drug that binds the toxins in their bloodstream and allows it to be removed from their bodies.
However, those in too much pain are put down, and many still die despite treatment.
