摘要: Captive animals may lose the ability to recognize their natural predators, making conservation programs more susceptible failure if such are released into wild. Collared peccaries American tayassuids that vulnerable local extinction in certain areas, and being conducted. Captive-born intended for release wild Minas Gerais state, southeastern Brazil. In this study, we tested of two groups captive-born collared predators they were habituated humans. Recognition tests performed using models (canids felids) non-predators animals, as well control objects, a plastic chair; human was also presented peccaries, separate stimulus. Anti-predator defensive responses fleeing threatening displays not observed response predator models. Predator detection behaviors both from visual olfactory cues displayed, although specifically targeted at These results indicate unable model predators. Habituation effects, particularly on anti-predator behaviors, with 1-h presentation across testing days. Behavioral humans did differ those other Thus, these be wild, should undergo training sessions enhance chances survival.
