Bald Eagle — Conservation Status, page 2

A 1972 ban of the harmful pesticide DDT, along with passage of the Endangered Species Act in 1973 helped set the eagle on a path to recovery. Since then, Bald Eagle populations have grown, and the species was reclassified as “threatened” in 1995. Although the eagle was considered for removal from the federal Endangered Species List in 1999, the species’ full recovery is far from complete. Populations in the lower 48 states remain relatively low, and the birds’ reproductive success along Great Lakes shorelines remains poor. Many eagles still show high pesticide residue in their systems, and loss of nesting habitat to development presents a continuous challenge.
