13 Wild Zoo Escapes That Actually Happened

Zoos are built around one very important assumption: the animals stay on their side of the barriers. Every so often, an orangutan, tiger, gorilla, panda, or other resident decides that arrangement is apparently negotiable.

Some escapes lasted only a few minutes and ended with everyone safely back where they belonged. Others caused lockdowns, evacuations, citywide searches, or much more serious consequences. A few animals even became minor celebrities for their ability to outsmart the humans trying to contain them.

Here are 13 remarkable zoo and wildlife park escapes that really happened, including an orangutan who repeatedly outwitted keepers, a panda that climbed its way to freedom, and three kangaroos who received some accidental help from a fox and a wild boar.

Ken Allen did not merely escape once. The Bornean orangutan became a San Diego legend after repeatedly finding ways out of his enclosure during the 1980s. His first famous escape came on June 13, 1985, followed by more that summer. Ken generally stayed around the zoo rather than trying to disappear into San Diego, calmly wandering public paths and inspecting his surroundings. Keepers eventually became so desperate to discover his methods that some disguised themselves as ordinary visitors to watch him. He still kept figuring out new ways to beat the system, earning the nickname "Hairy Houdini."

On Christmas Day 2007, a Siberian tiger named Tatiana escaped from her open-air enclosure at the San Francisco Zoo. She attacked three visitors, killing a 17-year-old and seriously injuring two others before police shot and killed her. Investigators and zoo officials spent months examining how Tatiana managed to get over the enclosure barrier. The incident became one of the most serious zoo escapes in modern U.S. history and led to major scrutiny of the facility's tiger enclosures and safety procedures.

In February 2019, chimpanzees at Belfast Zoo discovered that storm-damaged tree branches made a surprisingly effective ladder. The chimps propped a large branch against the wall of their enclosure and climbed up, with at least one making it onto a visitor pathway. Videos of the escape quickly spread online. The good news was that the chimps apparently decided freedom had been overrated and returned to their enclosure on their own. Sometimes the best escape plan apparently comes with a return policy.

Valerio, a 3-year-old jaguar, escaped from his habitat at New Orleans' Audubon Zoo before the park opened on July 14, 2018. Zoo veterinarians sedated him and secured him within about an hour, and no people were injured. The consequences for nearby zoo animals were much worse. Valerio attacked alpacas, foxes, and an emu, and nine animals ultimately died from the incident. Investigators determined that a break in the stainless steel cable barrier over his habitat likely provided the escape route.

Washington, D.C., briefly had a very adorable fugitive in June 2013. Rusty, a young red panda at Smithsonian's National Zoo, vanished from his enclosure and triggered a search that quickly took over social media. He was eventually spotted in a tree in the nearby Adams Morgan neighborhood and safely recovered. Zoo investigators later concluded that rain had bent bamboo and tree limbs together near the exhibit, effectively creating a leafy bridge that Rusty could climb across. He returned home unharmed and with considerably more name recognition than when he left.

A keeper error led to a tragic escape at England's Dudley Zoo in October 2018. An enclosure door was accidentally left open, allowing an 8-year-old snow leopard named Margaash to get out. Staff attempted to persuade him to return, but with darkness approaching and the animal close to surrounding woodland, the zoo determined that using a tranquilizer would take too long to guarantee public safety. Margaash was shot. The zoo later reviewed its security procedures and took disciplinary action over the mistake.

This was less an ingenious escape than a natural disaster ripping a zoo apart. Severe flooding struck Tbilisi, Georgia, in June 2015 and destroyed animal enclosures at the city's zoo. Lions, tigers, bears, wolves, a hippopotamus, an elephant, and other animals escaped into the surrounding area. Images of zoo animals wandering through a flooded capital circulated around the world. Some were safely recovered, while others died during the flooding or afterward. The sight of a hippo walking through a major city square became one of the disaster's most unforgettable images.

London Zoo went into lockdown in October 2016 after silverback gorilla Kumbuka slipped out of his den. Despite dramatic early reports, he never reached public areas. A den door had not been properly secured, allowing Kumbuka into a staff-only service corridor. During his brief taste of freedom, he opened and drank roughly five liters of undiluted blackcurrant squash. Staff kept him calm until he could be tranquilized and returned safely. If you're going to stage a gorilla escape, apparently raiding the drinks cupboard is part of the itinerary.

Pulang, a 15-year-old female orangutan at Perth Zoo, managed a remarkably clever escape in July 2009. She pulled a rope loose inside her enclosure, used it to swing toward the edge, and climbed into a public area. Visitors were evacuated while staff coaxed her back inside, a process that took about 15 minutes. Zoo officials described Pulang as extremely intelligent and later reviewed the security of the primate enclosure. She was definitely not, as some retellings claimed, the zoo's elderly 62-year-old orangutan Puan.

In April 2000, a 4-year-old cheetah named Casper somehow made it out of his stone-walled enclosure at the Cincinnati Zoo. His freedom lasted roughly 15 minutes. Rather than sprinting through Cincinnati at cheetah speed, Casper wandered into a shallow lake and took refuge on a small island. Zoo staff tranquilized him and carried him safely back. Officials were left trying to figure out how he had managed to clear an enclosure wall roughly 15 feet high in the first place.

Jabari, a western lowland gorilla at the Dallas Zoo, escaped his habitat on March 18, 2004. The roughly 340-pound gorilla cleared a wide trench and tall retaining wall that officials had not believed a gorilla could cross. Four visitors were injured during the roughly 40-minute incident before police shot and killed Jabari. The zoo later investigated how he had accomplished the escape and made extensive changes before reopening the habitat.

In June 2020, Copenhagen Zoo discovered that even an enclosure surrounded by electric fencing was not enough to discourage a determined panda. Seven-year-old Xing Er climbed a metal pole and worked his way out of the panda habitat before the zoo opened for the day. A janitor found him wandering in the garden. Staff tranquilized Xing Er and returned him safely to his enclosure, then began examining exactly how a giant panda had managed to turn into a surprisingly capable escape artist.

This may be the closest any zoo escape has come to an animal heist movie. In August 2012, three kangaroos escaped from a wildlife park near Frankfurt, Germany, with some completely accidental help from other animals. A fox had dug a hole beneath the kangaroo enclosure, allowing the trio out. A wild boar had separately dug beneath the park's outer fence, giving two of the kangaroos a path completely outside the facility. Two were soon recovered, while staff continued searching for the third. Somewhere, a fox and a wild boar deserved accomplice credits.
