Introduced males were also less likely to establish and hold on to territories. Male otters and North American swift foxes, for instance, were less likely to mate and breed, probably because they lacked the social mating behaviors to compete successfully with wild rivals, Jule said. Zoo-raised predators also underperform socially in the wild, the study said. "Captive-born animals have less natural fear of other large carnivores," she said. "A lot of them are shot, poisoned, deliberately trapped, and killed," she said.Īfrican hunting dogs released in southern and eastern Africa are also regularly attacked by lions, Jule noted. The African hunting dog, or the African wild dog, was among the reintroduced species found to be especially vulnerable to humans, Jule said. More than half of the fatalities were attributed to human causes, such as vehicle collisions and deliberate shootings.Ĭaptive-born carnivores were also more likely to starve to death than their wild-bred counterparts, as well as become more susceptible to viruses and diseases, the study showed. The study team looked at survival rates for 17 species of reintroduced mammals, including tigers, wolves, lynx, cheetahs, brown bears, and otters. But here it is finally quantified, and the extent of the problem is critical," she said. "We have suspected for some time that captive-born animals fared less well than wild animals. "Their lack of hunting skills and lack of fear towards humans are major disadvantages," she said. "Animals in captivity do not usually have the natural behaviors needed for success in the wild," said lead author and animal behavior researcher Kristen Jule. The study, which reviewed 45 carnivore reintroductions worldwide, questioned the role of zoos and captive-breeding programs in conservation efforts. The odds of animals such as tigers and wolves surviving freedom are only 33 percent, according to a team of researchers from the University of Exeter in the United Kingdom. Most large, captive-bred carnivores die if returned to their natural habitat, a new study has found.
