 In response to the capture of all the wild individuals of the California condor, in 1988 the US Fish and Wildlife Service began a reintroduction experiment involving the release of captive Andean condors into the wild in California. Only females were released to eliminate the possibility of accidentally introducing a South American species into the United States. The experiment was a success, and all the Andean condors were recaptured and re-released in South America before the reintroduction of the California condors took place.
