Four African long-tailed shrikes escaped from an aviary at the Minnesota Zoo last summer when a worker inadvertently left open a door to the enclosure. The previous year the zoo lost a Eurasian eagle owl that escaped its enclosure. It was later found dead along a roadside.
Escaped animal proceduresWhen an animal escapes, guests are immediately evacuated from the area and escorted to secured buildings on zoo grounds by the zoo's emergency response team (veterinarians armed with tranquilizer equipment, zoo firearms team and animal management staff).
AZA-accredited zoos and aquariums have collaborated on breeding and reintroduction programs that have helped save at least nine species like California condors, black-footed ferrets, Przewalski's horse, golden lion tamarins, American red wolves, and more from the brink of extinction.
Six Species Saved From Extinction by ZoosAs of 2017, 1,000 animals had been restored to the wild, while thousands more were living in zoo environments. Przewalski's Horse: The only truly wild species left in the world, Przewalski's Horse is native to the grasslands of Central Asia.
In a comically unfortunate series of events, five African lions recently escaped their enclosures at Sydney's Taronga Zoo during an overnight guest program.
Most of these animals were born in captivity, with zoos playing a major role in such projects, while other schemes involve moving wild animals to new areas. This study reviewed 45 case studies, involving 17 carnivore species, and found that only 30% of captive animals released survived.
London Zoo gorilla drank five litres of blackcurrant juice after escaping enclosure. The silverback gorilla whose escape sent ZSL London Zoo into lockdown made an “opportunistic” exit through two unlocked doors into a corridor where a keeper was working, the zoo said.
Most animals confined in zoos are not endangered, nor are they being prepared for release into natural habitats. In fact, it is nearly impossible to release captive-bred animals, including threatened species like elephants, polar bears, gorillas, tigers and chimpanzees into the wild.
“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 need to be very careful about introducing diseases to a wild population. But for some animals, if we proceed scientifically and thoughtfully, it can be done.”
Even a lifetime in the most humane zoo will have left animals too affected by years of sheltered existence. Captive animals seldom learn crucial survival skills and often 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.
In summary, lions in captivity suffer a high level of stillbirths, a much higher frequency of behavioural abnormalities compared to smaller carnivores, and skeletal deformities likely to cause neurological complications.
The 215 AZA-accredited zoos and aquariums in the U.S. serve more than 183 million annual visitors and support over 212,000 jobs, generating $24 billion in the total value of goods and services generated directly and indirectly as a result of annual outlays by AZA members and their visitors.
