Osprey #17-0622 update

Osprey #17-0622 was found dead in his enclosure on the morning of May 10. 

The bird's health deteriorated during the days leading up to its death; its lead levels persisted, and unfortunately, the bird died before completion of the second round of chelation treatment. 

Acute chronic lead poisoning can be difficult to treat, as lead hides in the bones when ingested in small amounts over a prolonged period of time.  The small amount is not enough to cause neurologic symptoms, but levels build up in the bones after passing through the blood stream.
