About Bald Eagle
- Bald eagle, the only eagle solely native to North America, and the national bird of the United States.
- IUCN Status: Least Concern
- The bird is not actually bald; its name derives from the conspicuous appearance of its white-feathered head.
- Human predators and use of DDT pesticide are major threats to this bird.
- DDT (Dichlorodiphenyltrichloroethane) is used as pesticide for agricultural uses, But this pesticide accumulated in the birds’ tissues and interfered with the formation of the shells of their eggs; the thin, weak shells laid by heavily contaminated birds were easily broken and fewer young were produced.
- Their population dropped to just 450 nesting pairs in the 1960s.
Why in the news?
- In the recent report published by the United States, the population of the bald eagle has quadrupled since 2009.
- The step of banning DDT pesticide since 1972 has been a great boon for this bird.
