We analyzed whether captive-bred greater rheas conserve antipredator behavior, and evaluated the efficiency of antipredator training by recording survival after reintroduction into the wild. Training involved 12 individuals and consisted of a stimulus representing the natural predator (taxidermized puma) paired to an aversive stimulus (simulated capture). The control stimulus consisted of an innocuous object (chair) that was not paired to the aversive stimulus. Thirty and 60days after the last training session, we presented the trained and control individuals (nine untrained individuals) to the predator stimulus, which was not paired to the aversive one. All of the greater rheas showed vigilant and running behaviors in the presence of the predator model. Trained individuals did not discriminate between a predator and a non-predator stimulus but they recognized the predator up to 2months later. Survival was nil 8months after release. However, only one individual was killed by a puma, whereas the remaining individuals died due to dog attack and poaching. Training did not increase survival of reintroduced greater rheas because of the failure to consider other potential predators, such as dogs or humans. Therefore, captive breeding might have affected greater rheas' behavior by preventing them from recognizing man as a predator.
