Bald Eagle — Conservation Status

When the pilgrims landed in North America, the estimated Bald Eagle population was 500,000 birds. It is said that at that time, an eagle’s nest existed for every 10 miles of Great Lakes shoreline. As with other predators, however, eagles were trapped, shot and poisoned for many generations. The birds suffered particularly steep declines in the mid-20th century because of habitat loss and pesticide and heavy metal poisoning. By 1970, fewer than 1,000 Bald Eagles were raising broods in the continental United States.         next page >>
