If you find a dead bald eagle, you are legally bound to mail to gov't

Falconers with appropriate licenses and wildlife rehabilitators are also allowed to possess eagles and eagle parts.
The article is inconsistent -- at the beginning the author says only Native Americans can possess eagles/parts, then at the end he says "Go ahead and pick up a dead eagle." You can't have it both ways. It is absolutely illegal for a regular citizen to disturb an eagle, dead or otherwise. Picking it up is "possession."
Same goes for all migratory, non-game birds, technically speaking; they are protected by the Migratory Bird Treaty Act.
If you find one and want it sent to the Repository, please call your state Fish & Game office to send someone out.
However, the law does bend for a regular citizen who finds an injured live raptor. They can take to a vet or rehab with no legal consequences.
