Wind turbines can kill and injure birds, including eagles, potentially exposing their operators to criminal liability under the Act, even those which have taken steps to reduce eagle mortality.

"Along with the passage of the Endangered Species Act, the United States ban on DDT is a major factor in the comeback of the bald eagle (the national bird of the United States) and the peregrine falcon from near-extinction in the contiguous United States. DDT is similar in structure to the insecticide methoxychlor and the acaricide dicofol. It is highly hydrophobic and nearly insoluble in water but has good solubility in most organic solvents, fats and oils. DDT does not occur naturally and is synthesised by a Friedel–Crafts hydroxyalkylation reaction between chloral () and chlorobenzene (), in the presence of"

The pesticide was banned in 1972 eventually leading to the restoration of many birds and larger mammals. For example, the bear population doubled from the 1980s to 6,000 in 2013. In 1964, the US Supreme Court forced ""one-man, one-vote"" redistricting on Vermont, giving cities an equitable share of votes in both houses for the entire country.

"Moreover, small animals ate plants that were sprayed with other pesticides which were then eaten by the birds of prey. More than 100,000 bald eagles were killed in Alaska from 1917 to 1953. Public awareness arose during this time, and many groups and individuals dedicated to make the conservation of eagles a national issue. The Patuxent Wildlife Research Center in Maryland started to breed eagles in captivity to increase the population numbers. The goal was to breed enough birds to increase the population of bald eagles in areas where the population was declining and to re-introduce them in those areas"

By the 1960s, much of the forest had grown back, but residential development as a suburb of Washington posed another threat. In 1969, local residents and conservation groups achieved the establishment of the Elizabeth Hartwell Mason Neck National Wildlife Refuge, with the specific objective of protecting the bald eagle. This, along with Mason Neck State Park and Pohick Bay Regional Park, provides a variety of recreational activities while preserving the land's natural resources.

"it interfered with the bird's calcium metabolism, making the bird either sterile or unable to lay healthy eggs. Female eagles laid eggs that were too brittle to withstand the weight of a brooding adult, making it nearly impossible for the eggs to hatch. It is estimated that in the early 18th century, the bald eagle population was 300,000–500,000, but by the 1950s there were only 412 nesting pairs in the 48 contiguous states of the US. Other factors in bald eagle population reductions were a widespread loss of suitable habitat, as well as both legal and illegal shooting. In 1930"

However, the associated nontarget mortality, i.e., the deaths of animals other than the rats, was significant. Some nontarget mortality was expected, but the actual quantity greatly exceeded what was predicted. The Ornithological Council reported that more than 420 birds were killed as a result of the rat eradication program.

Biologist Rachel Carson consequently argued against spraying elms and for improved sanitation, which she saw as having been more effective in areas with earlier and greater experience countering Dutch elm disease. Although modern critics of Carson have argued that the bird deaths were caused by other factors such as mercury poisoning in the soil, spraying against elm bark beetles declined very rapidly after 1962, a trend aided by fungicides without dangerous side-effects being discovered for the first time after many years of research.

"Three Catalina Island Conservancy wildlife biologists continue to monitor the population through pit tagging, trapping and inspection. The Institute for Wildlife Studies, a separate conservation organization, has worked to restore bald eagles to the island on Conservancy land since the late 1970s. Bald eagles had been common on the island until the 1960s, when it is believed that the effects of dumping the pesticide DDT off the coast of Southern California made it impossible for eagles to successfully hatch their young. The reintroduction of the bald eagle to the island may also edge out an invasive golden eagle population that"

In the late 1980s, Dorset County Council asked the Institute for Freshwater Ecology (now the Centre for Ecology and Hydrology), then based in Wareham, Dorset, to investigate a means of ameliorating the problem. They suggested using a biological insecticide, ""Bacillus thuringiensis israelensis"" (Bti), which was sprayed into the weed beds, resulting in the destruction of 80–90% of the Blandford fly larvae and a corresponding reduction in the numbers"

Bald eagles have also been killed by oil, lead, and mercury pollution, and by human and predator intrusion at nests. The species was first protected in the U.S. and Canada by the 1918 Migratory Bird Treaty, later extended to all of North America.

Twenty-five others have been down listed from ""endangered"" to ""threatened"" status.

In 1972, the United States Environmental Protection Agency (USEPA) banned DDT usage in the United States and limited the use of other pesticides. There has been a decline in chemical contaminant levels in brown pelican eggs since then, and a corresponding increase in its nesting success. It became extinct in 1963 in Louisiana.

When the bald eagle was removed the FWS had collected data on 9,789 breeding pairs. In 1983, the Northern States Bald Eagle Recovery Plan was proposed.

In the 1980s, California ground squirrels, considered agricultural pests, were poisoned by the anticoagulant rodenticide, Chlorophacinone. In turn, the poisonings caused golden eagles, as one of the major natural predators of California ground squirrels, to die in turn.

This species, as well as the Indian vulture and slender-billed vulture has suffered a 99% population decrease in India and nearby countries since the early 1990s. The decline has been widely attributed to poisoning by diclofenac, which is used as veterinary non-steroidal anti-inflammatory drug (NSAID), leaving traces in cattle carcasses which when fed on leads to kidney failure in birds. Diclofenac was also found to be lethal at low dosages to other species in the genus ""Gyps"". Other NSAIDs were also found to be toxic, to ""Gyps"" as well as other birds"

This average level of thinning was not thought likely to result in significantly more breakage overall, however individual clutches that had been even thinner might have broken.

The pesticide interfered with the bird's calcium metabolism which resulted in thin-shelled, easily broken or infertile eggs. Possibly because of the banning of DDT in many countries in the early 1970s, together with reduced persecution, the osprey, as well as other affected bird of prey species, have made significant recoveries."
