DDT was considered the main reason the bald eagle was put on the endangered species list. DDT was a spray pesticide that often ran off into rivers and contaminated fish. DDT decayed slowly making this problem even worse. When a bald eagle ate a contaminated fish the pesticide caused the eagle to receive less calcium. The lack of calcium resulted in weaker eggs so when the bald eagle would sit on the egg the egg would break.


    Poachers killed bald eagles for their feathers and talons. Today the migratory bird treaty act and bald and golden eagle protection act protect bald eagles from taking, transporting, selling, bartering, trading, importing and exporting, and possession of eagles, making it illegal for anyone to collect eagles and eagle parts, nests, or eggs without a permit.
