The PeregrineFund (named after the bird of prey of the same name the peregrine falcon) is a non-profit organization founded in 1970 that conserves threatened and endangered birds of prey worldwide. The successful recovery in the United States of the peregrine falcon, which was removed from the U.S. Endangered Species List in 1999, enabled the organization to expand its mission to include other endangered raptors around the world. The Peregrine Fund is headquartered at its World Center for Birds of Prey in Boise, Idaho, on a 580-acre (2.3 km2) campus with breeding and research facilities, an administrative office, interpretive center, research library, and archives.
