Aplomado Falcons were once widespread residents of the American Southwest, but by the 1950s, they'd disappeared entirely from the region. Loss of habitat, loss of prey, and pesticides all played a role. But in the 1980s, a group called The Peregrine Fund began breeding captive Aplomado Falcons. Over the next 25 years, 1,500 fledglings were set free in South Texas. At the same time, conservation pacts with private landowners provided more than two million acres of habitat.
