In 1983, the Northern States Bald Eagle Recovery Plan was proposed. This plan, like the Patuxent Wildlife Research Center`s plan, aimed to restore self-sustaining bald eagle populations in northern regions. Their original goal was to have 1,200 breeding sites occupied by the year 2000, i.e. «the local area associated with a pair of territorial eagles and containing one or more nesting structures» spread over at least 16 states in the region. The objective was to achieve an annual productivity of 1.0 young per occupied nest. The plan included specific tasks, characterized by the following categories: 1. identification of current populations and habitat status, 2. determination of the minimum population and habitat necessary to achieve the objective, 3. protection and enhancement of bald eagle habitats, and 4. Establishment of an information and communication coordination system. To accomplish these tasks, annual surveys, habitat assessments and site-specific management planning were conducted to improve communication and coordination.
They worked to improve habitat conditions, especially in winter, to maximize the survival rate of these eagles.  Initially, the religious use of eagle parts by Native Americans led to a challenge to BGEPA based on whether the law altered the rights of Native Americans to hunt eagles on their tribal lands. [Initially, the courts were divided on whether the law changed contract rights, as the law did not explicitly say whether this was the case] BGEPA does not explicitly indicate whether it is cancelling or modifying these contractual hunting rights. In 1986, however, the U.S. Supreme Court resolved any confusion on this issue by ruling that BGEPA had modified these contractual rights so that no one could take eagles without permission. As a result of this position, Native American legal challenges have shifted from treaty-based arguments to the exercise of religious freedom. The term «catch» includes pursuit, shooting, shooting, poisoning, wounding, killing, catching, catching, assembling, harassing, or disturbing (16 U.S.C. 668c; 50 CFR 22.3). DDT is a persistent toxin known to bioaccumulate in fish populations. A major component of the diet of bald eagles consists of fish, which in turn have exposed the population of these eagles to the toxin. In contrast, the golden eagle mainly eats rabbits, hares, ground squirrels and other common prey that have allowed them to escape the harms of DDT and other related chemicals.
Unlike bald eagle eggshells, golden eagle shells retain their thickness and cannot tear. DDT was banned in the United States in 1972. Other factors played a role in the decline of bald eagles and golden eagles in the 1950s, 1960s and 1970s. For example, one source of mortality for bald eagles is the bioaccumulation of toxins in their reproductive system and bloodstream.  Dieldrin and polychlorinated biphenyls are pollutants in the environment that have affected eagle populations. These chemicals are persistent in the environment and are known to harm these birds. Human activities are another reason for the decline in bald eagle populations. Habitat change and nest disturbance affect reproduction and foraging. In addition, power lines can expose these birds to possible electric shocks. For many years, power distribution companies have worked with wildlife biologists and government agencies to research, develop and deploy safer power lines and poles for all birds, including eagles. Some new power lines in non-urban areas have been built to «birds of prey» building standards.
 Another thing that affects Adler is animal trapping. Traps are set on the ground to catch or kill furry animals. Captive animals can bait eagles, which then have the potential to be injured or injured by the traps. Since eagle claws play a crucial role in foraging, an injured bird can starve to death if left injured for a long period of time. Hunting can also have a direct or indirect effect on eagles. Duck and geese hunters who shoot but fail to retrieve their game can have adverse effects on eagles. When an eagle finds and consumes food contaminated with lead shot, lead accumulates in the bird and can cause toxicity and even death. After all, most farmers and ranchers often shoot bald eagles and golden eagles, which they see as a threat to their livestock. Unfortunately, many assumptions are made about bald eagles and golden eagles because they think they are pests.
The two eagles search for dead animals that are killed by other factors.  Measures taken to protect bald eagles and golden eagles, such as the Bald Eagle and Golden Eagle Protection Act of 1940, the prohibition of DDT in 1972, the Endangered Bald Eagle Act of 1973, and the United States Fish and Wildlife Service program of 1992 (phasing out the use of lead shot for hunting). , waterfowl), All have contributed to elevating their status from «vulnerable» to «threatened». The bald eagle is the national bird of the United States, and as such, most Americans would not intentionally kill it. But what if you mistake the majestic bird for something else or accidentally pull it out somehow? In 2007, the USFWS removed the bald eagle from the federal endangered species list. Although the bald eagle is no longer protected under the Endangered Species Act, it is still protected under the Bald and King Eagle Protection Act and the Migratory Birds Treaty Act.
