Some controversy has existed over the origins of captive-breeding stock used by the Peregrine Fund in the recovery of peregrine falcons throughout the contiguous United States. Several peregrine subspecies were included in the breeding stock, including birds of Eurasian origin. Due to the extirpation of the eastern subspecies (Falco peregrinus anatum), its near extirpation in the Midwest, and the limited gene pool within North American breeding stock, the inclusion of non-native subspecies was justified to optimize the genetic diversity found within the species as a whole.. Such strategies are common in endangered species reintroduction scenarios, where dramatic population declines result in a genetic bottleneck and the loss of genetic diversity.
