Peregrine Comeback

Rachel Carson's Silent Spring, which came out in 1962, linked the pesticide DDT to the decline of many birds, including songbirds.  But Peregrine Falcons and other raptors had declined, too. When the birds ingested DDT, it caused their eggshells to thin and break under the weight of the incubating bird. With the ban of DDT, nesting success rebounded.
