Two years after the American peregrine falcon (Falco peregrinus anatum) was declared endangered, the United States banned DDT in 1972. The pesticide lingered in the environment, however, and by 1975, North America’s population of peregrine falcons hit a low of 324 nesting pairs. State and federal agencies worked with conservation groups to breed the species in captivity, with some 6,000 birds released into the wild since 1974. The species was removed from the U.S. endangered species list in 1999.
