The National Wildlife Property Repository, a government facility outside of Denver, stores more than a million products of the illegal wildlife trade, from tigers and bears to elephant ivory. These items are confiscated at points of entry around the United States, and sent to the Repository to be destroyed or used for educational purposes.
The bit about the National Eagle Repository is especially interesting. Under federal law, every dead eagle (and eagle parts, including feathers) must be sent to the repository, where they are made available for distribution to native tribes.
The primary objective of The National Eagle Repository (Repository) is to receive, evaluate, store and distribute bald and golden eagle carcasses, parts, and feathers to tribally enrolled Native Americans of Federally recognized tribes throughout the United States for religious purposes. The Repository serves as the collection and distribution point for bald and golden eagle salvages each year by State and Federal wildlife officials.
