In the Midwestern region of North America, a recovery program for Peregrine Falcons Falco peregrinus has been underway since 1982. The historic cliff nesting population was extirpated from the region by 1964 due to problems associated with organochlorine pesticides. Original recovery efforts centered on reestablishing Peregrines at historical sites. Because of predation and habitat changes, these efforts were unsuccessful. At the same time, the amount of urban nesting within the region was increasing. Based upon documented population and dispersal trends, we have suggested an approach at establishing and increasing populations of urbah nesting Peregrines through planned placement of nest boxes and sequential releases of captive-produced young. Many lessons have been learned throughout this recovery program which if addressed, may increase the chances of success for similar programs being initiated elsewhere.
