American Bald Eagle - status in your state
The bald eagle was made the national bird of the United States in 1782.
The image of the bald eagle can be found in many places in the U.S., such as on the Great Seal,
Federal agency seals, the President's flag, and on the one-dollar bill.1
The Bald Eagle is protected by the United States government and many state governments.

The bald eagle first gained federal protection in 1940, under the Bald and Golden Eagle Protection Act. The law curbed illegal hunting and shooting of eagles for their feathers. They began to recover.
But eagles, as well as other birds, soon fell victim to another threat: DDT. After World War II, the USDA encouraged spraying DDT (dichloro-diphenyl-trichloroethane) to control mosquitoes in coastal areas. Farmers used DDT to control agricultural pests. When it rained, DDT would wash off the soil and into the waterways. There, it was absorbed by aquatic plants and animals. Fish ate the plants and animals, and then eagles ate the fish. When eagles ate contaminated fish, they would then be poisoned. DDT prevented the proper formulation of calcium necessary to produce strong eggshells. Consequently, the thinned eggshells cracked when an adult bird tired to incubate them. Few chicks were born. The Environmental Protection Agency banned the use of DDT on December 31, 1972.
The U.S. Fish and Wildlife Service officially listed the bald eagle as a national endangered species in 1973.
An “endangered” species is one that is in danger of extinction throughout all or a significant portion of its range. Watch - Saving the Bald Eagle video @ The Futures Channel
A “threatened” species is one that is likely to become endangered in the foreseeable future.
Through captive breeding programs, reintroduction of eagles into their historic habitat, protecting nest sites during the breeding season, conserving roosting habitat for food and shelter and enforcing the law against those people who illegally killed eagles, the Endangered Species Act provided protections for the bald eagle.
The last year the FWS conducted a national bald eagle census was 2000. They estimated there were 6471 nesting pairs of bald eagles. In 2007, they announced that they were removing the American Bald Eagle from the Endangered Species List, because there was an estimated high of 9,789 breeding pairs.

Should someone intervene?
Bald Eagles regularly nest along the Susquehanna River in PA. In 2011, a growing number of fishermen and environmentalists were concerned due to the decline in smallmouthed bass populatioons and the blotches that were appearing on the fish. What implications could this have for bald eagles in PA?
