Species Recovery, Peregrine Falcon


“By the mid 1960's, there were no peregrines in the eastern United States and the decline spread westwards so that by the mid-70's western populations had declined by up to 90 percent....Loss of habitat, shootings, egg collecting and other human disturbances had weakened North American populations for decades but drastic declines didn't occur until after the widespread use of a popular insecticide - DDT..... the peregrine falcon provided humans a warning as how chemical pollution can disrupt the environment and the life around it.... Encouraged by the EPA's banning of DDT in 1972, recovery projects began to take shape.” In 1999, the peregrine falcon was removed from the endangered species list.
