How Can Training An Animal In Captivity Be Difficult
For some species, the road to release is a long one.
In many ways, humans have vastly improved how we treat captive wild animals. Once Romans routinely tortured and slaughtered lions, leopards, rhinos and even elephants in the Colosseum and carry-baiting was commonplace across Europe until the 19th century.
Today, with circus animals increasingly becoming a thing of the past (especially now the British authorities has banned them entirely) , what happens too all those newly-freed animals that spent their lives in zoos and circuses or as pets? Tin can any brute, afterwards years in captivity, always be freed?
Even a lifetime in the most humane zoo will have left animals too affected by years of sheltered being. Convict animals seldom acquire crucial survival skills and frequently are too habituated to human contact. Lacking a natural fear of humans, they are vulnerable to poachers and ill equipped for life in the wild.
No case makes this more heartbreakingly obvious than the story of Keiko, the orca star of Free Willy (1993). A massive letter-writing campaign demanding his freedom led to Keiko being flown to Iceland in 1999 for release. Unfortunately, Keiko was ill-equipped for survival in the wild. Captured at a very immature age and likewise accustomed to homo contact, several attempts to aid him join a wild pod failed. In the end, Keiko swam into a harbor in Norway, actively seeking the company of humans. He never managed to integrate with a wild population, struggled to hunt, and eventually died of pneumonia in 2002.
"Release to the wild is not automatically in the best interests of the animal," says Dr Chris Draper caput of animal welfare and captivity at Built-in Free – a charity that campaigns to keep animals in the wild. "The damage was done when that animal was brought in from the wild in the first place; it is dangerous to presume can could be released without simply adding to the misery."
For fish, reptiles, and amphibians, reintroduction can be fairly straightforward: frogs for instance can often be bred in huge numbers in the lab and released to the wild. But with circuitous mammals such equally primates, large cats, elephants, dolphins and whales, who may require years of instruction from their mothers, and an entire group of other members of their species in which they tin can thrive every bit adults, reintroduction is far more difficult.
"For the longest time, the thought of returning animals such as large mammals to the wild was just off the table, only now we're seeing people in the field questioning the long-held belief that it'southward impossible to return convict animals to their natural habitat," says Katie Moore, deputy vice president of conservation and animate being welfare for NGO the International Fund for Creature Welfare . "Yes, in a lot of cases it is still impossible, especially if the animals have been traumatised or were very young when captured. And you demand to be very careful well-nigh introducing diseases to a wild population. Only for some animals, if we keep scientifically and thoughtfully, it tin can be done."
Consider the African King of beasts and Environmental Inquiry Trust (ALERT) in Zimbabwe, which for 15 years has worked to introduce lions to the wild. "Yes, lions can get habituated to humans, but nosotros make sure the ones we released are not habituated," says Dr Norman Monks, CEO of Alert.
Their method of release involves multiple stages, which somewhen sees the release of wild offspring from previously convict adults. First, lions that take been habituated to humans are released into a large enclosure with prey species to hunt. Next, those animals (which are never handled past humans again) eventually form a pride and produce new cubs. Then those cubs, who accept grown together and formed social bonds, are somewhen released equally a pride.
"This is important, every bit we would non want to put these cubs into the wild if they were not a cohesive pride that would treat each other." Considering lions are highly social animals (and the only social species of cat), and their innate need to live within a pride needs to be taken into business relationship when preparing them for release to the wild.
Many other groups are challenging quondam notions and working to develop new techniques tailored to the needs to different species to achieve what was in one case idea incommunicable, such equally the Chimpanzee Rehabilitation Trust, Wildlife Vets International, and Built-in Costless.
Wild release is easier for some animals than others, and the needs of individual species need to exist carefully taken into account.
"I species that would be incredibly problematic is polar bears. They live in a highly specialised environment, and need to acquire the skills to survive in that surroundings from their mothers. Learning those skills in a pre-release context would be next to incommunicable," says Dr Draper. "Merely other kinds of bears seem to exist reasonably successful when released back to the wild. But it depends so much on the individual animal: the historic period it was captured, whether it was bred in captivity, its experiences in captivity, any kinds of trauma, health, early nutrition. There is just no magic recipe."
For many species, just every bit with lions, frequently the key is to release animals in groups. "Even chimpanzees that have lived in laboratories for many years tin can practice pretty well when released in groups onto protected islands," says Dr Draper.
Since 2006, conservationists at Orangutan Rescue in Indonesia have taken in orangutan infants who frequently accept been kept as pets after their mothers were shot by famers for raiding crops. In the wild, an orangutan would spend up to nine years with its mother; an extraordinarily long time, fifty-fifty for a primate. This ways orphaned orangutans require an exceptional corporeality of nurturing and education. Infants will spend anywhere from 5 to 10 years at the middle beingness taught key survival skills such every bit how to climb copse, crack coconuts, fish for termites, and also that they need to fear threats such as spiders, snakes – and humans.
We try to be hands-off equally much as possible. We attempt non to let them get attached to u.s., considering nosotros need them to larn non to trust people"
"We endeavor to be easily-off every bit much equally possible. Nosotros try non to let them become attached to us, considering we need them to learn non to trust people," says Karmele Llano Sanchez, program director of Orangutan Rescue at International Animate being Rescue. "The fundamental is that they learn more from each other than they do from us: one fauna will learn a skill very speedily, and then go on to teach others. This is how they can re-learn how to exist orangutans again. It takes many years and a lot of effort, but it has been surprisingly successful – I didn't recall the release program would become as well as it is. Even wild orangutans that take been brought to united states after forest fires with injuries, or who have gone through starvation, can exist brought back into skillful wellness and returned to the wild."
Rehabilitating an orangutan doesn't come cheap: with the costs of fauna care at $250 a calendar month, information technology may price $five,000 or $10,000 to somewhen release an fauna, and their operations are always express by funds.
In that location nonetheless is an upside to the high costs that come with caring for orangutans. "Yes the costs are high, but the money goes mostly to paying guides and trackers that follow them in the wild once nosotros release them – we employ a lot of people," says Sanchez. "This mode we tin go the buy-in of the customs. It is ultimately an first-class mode to provide an alternative income to hunting or logging."
This points to one of the biggest challenges with reintroduction: finding suitable habitats in a world where hunting, logging, poaching and agriculture are erasing the wild places of the globe.
"Demand for palm oil is growing, and so the trouble of orphaned orangutans is merely going to get worse considering Malaysians are producing palm oil for the rest of the earth," says Sanchez.
"The dream is to never say never, merely the reality of the world we live in means that even if the creature is physically capable of doing this, finding suitable release sites is extremely challenging," says Dr Draper. "But we take to try. Yeah, it is time consuming and information technology is expensive, but if information technology is possible, we have to try, simply because is the right thing to practise."
For some animals, reintroduction will e'er be difficult, such equally baby elephants, or pet cheetahs, both of which habituate to human intendance very chop-chop, says Moore of IFAW. But we've only but started to challenge old ideas about reintroduction, and we take much to learn.
"If we don't push button boundaries we will never know what is possible," she says.
