"The recovery of the American Peregrine Falcon (Falco peregrinus anatum) (Peregrines) following the species' near total disappearance from much of the United States is a remarkable story of cooperation among private and public institutions. Peregrine populations were at their lowest in the 1960s and early 1970s, when Peregrines were eliminated from the eastern United States and across the Midwest, and reduced to a few hundred pairs at most in the western United States and Mexico .Due to a ban on the use of DDT and other chlorinated hydrocarbons, and to successful captive breeding, rearing, and release of over 6,000 Peregrines, there are now over 2,000 pairs breeding each year across the United States (White et al. 2002), more than 400 pairs in Canada (U. Banasch, pers. commun. Feb. 7, 2003), and an estimated 170 pairs in Mexico (Enderson et al. 1995); in addition there are probably as many unpaired "floaters" as paired birds across their range (White et al. 2002). As a result of this comeback and because other recovery goals such as estimates of productivity, thicker egg-shells, and reduced levels of contaminants were nearly completely met in all recovery regions, the Peregrine was removed from the FWS List of Threatened and Endangered Species on August 25, 1999" P. 1 [7].
