However, over the next 70 years we almost lost the eagle, as it was forced to the brink of extinction.In the 1960’s the National Audubon Society had completed a survey showing there were only 417 breeding pairs of eagles left in the lower 48 states. After searching for what might have been causing the decline of the eagles, scientist discovered the culprit was DDT, or Dichlorodiphenyltrichloroethane, a pesticide that started being used in the 1960’s. Unknown at the time, DDT caused eagles and other birds to absorb less calcium, so that when they laid their eggs, the shells, weakened from the chemical, would be crushed when the parents nested over them. This led to a rapid and terrible decline in bird populations all over the countryIn 1973, the use of DDT was banned and that same year the Endangered Species Act was passed by Congress, giving protections to dozens and dozens of species on the brink of extinction. Through captive breeding, protection laws and stopping the use of DDT, the bald eagle was downgraded to a threatened species in 1994. By 2007, they had made such a comeback that they were taken off the endangered species list entirely
