The Return of Bald Eagles

In 1782, the bald eagle was named the U.S. national symbol—representing strength, courage and freedom. Today it could also be considered a symbol of survival. A few decades ago, the bald eagle was dangerously close to becoming extinct throughout the lower 48 U.S. states. Today, they're back from the brink and doing better than ever.

Habitat loss, over-hunting and the now-banned pesticide DDT were largely to blame for the eagles' rapidly declining numbers between 1870 and 1970. In Indiana, bald eagles were extirpated by 1900 due to the loss of wetland habitats. As breeding pairs continued to decrease in numbers throughout the country, it was apparent that something had to be done. In 1972 DDT was banned in the U.S., and in 1978 the bald eagle was listed as endangered. In August 2007, the U.S. Fish & Wildlife Services removed the bald eagle from the endangered species list as a result of their remarkable recovery.

 In winter, bald eagles are best seen near dams and power plants where open water abounds.
