There are many independent organizations that protect bald eagles, however, the two most prominent organizations are through the United States federal government: the National Parks Conservation Association and the U.S. Fish and Wildlife Service. These are the two organizations that enforce the federal laws that protect the bald eagles.
Due to the bald eagles problems with DDT pesticides as well as overhunting, the bald eagle was placed under federal protection by the United States federal government. The law, "The Bald and Golden Eagle Protection Act" was passed in 1940 and then amended in 1962. It does not allow people to sell or take any bald eagle bird regardless of its condition, either dead or alive, and the "take" included shooting, poisoning and killing the bird.
