Golden Lion Tamarin: Zlatka’s Incredible Return, the Monkey Stolen from Beauval Zoo

Ethan Hartwell | June 4, 2026

Found alive in Slovakia after a decade-long absence, this small endangered primate offers one of the most astonishing stories in the recent history of European zoos and serves as a stark reminder of the ravages of international wildlife trafficking.

Beauval’s Golden Lion Tamarin at the Heart of an Unprecedented Theft

On May 28, 2026, Beauval ZooParc welcomed a resident many believed they would never see again. This female golden lion tamarin, born in July 2013 at the zoological park in the Loire Valley, had been abducted during a theft. During the night of May 9–10, 2015, Beauval ZooParc fell victim to a meticulously planned nocturnal intrusion. The thieves left with seven golden lion tamarins and ten silvery marmosets, a total of seventeen small primates belonging to endangered species. These animals were part of international conservation programs designed to safeguard fragile populations.

The case sparked enormous emotion. Thousands of messages of support poured in. On social media, the campaign calling for the animals’ return echoed nationwide. Despite nearly twenty months of investigations involving several agencies and police services, no trace of the monkeys was found. In 2017, the French investigation was eventually closed without further action. For animal enthusiasts, the hope of ever seeing one of these primates again seemed definitively extinguished.

An Unexpected Discovery in Slovakia

The scenario, however, shifted in 2023. During a search at a private residence in Slovakia, authorities uncovered a female golden lion tamarin. The animal quickly drew the attention of specialists. Electronic identification played a decisive role. Thanks to the microchip implanted when she lived at Beauval, authorities were able to establish the animal’s origin beyond doubt. Investigations also revealed that a second chip had been added along her journey to mask her provenance. The small primate had thus passed through Germany before being found in Slovakia as part of an international wildlife trafficking operation. A lengthy administrative and judicial process then began to secure her restitution.

A Return to Beauval Charged with Emotion for This Golden Lion Tamarin

For three years, the animal stayed at a Slovak rescue center, where she received the care she needed while awaiting the case’s outcome. When the female finally rejoined France in the spring of 2026, the moment took on a particularly poignant dimension. Now 12 years old, she has spent most of her life far from her native habitat. The Slovak teams gave her the name Zlatka, which means “little piece of gold.” It is under this identity that she was tracked during her years in care.

Upon her arrival at Beauval, several veterinary examinations were carried out. The results were reassuring. Despite more than a decade without contact, the animal appears in overall good health. However, keepers note that she remains wary and reserved, a completely understandable demeanor after such a journey. The challenge now is to gauge her ability to rejoin social life. Golden lion tamarins typically live in small, highly structured family groups. After eleven years with little sustained contact with her conspecifics, reintegration could prove complex. For this reason, the animal is currently observed in a specially designed space within the park’s Chimpanzee and Orangutan House.

A Miraculous Survivor of International Wildlife Trafficking… Identified by Its Microchip

Beyond the emotion stirred by this story, Zlatka’s return highlights a global issue. Wildlife trafficking remains one of the most significant illegal trades on the planet. The golden lion tamarin is among the species particularly vulnerable. Native to Brazil’s Atlantic Forest, this small primate has long suffered from habitat destruction and the capture of individuals for the black market. About 4,800 individuals remained in the wild in 2023. Conservation programs have nonetheless led to a substantial improvement. By October 2025, the European breeding program counted 204 golden lion tamarins spread across several zoos.

The return of this female also stands as a concrete demonstration of the importance of identification systems and international cooperation. Without the microchip implanted at birth, it would probably have been impossible to connect the animal found in Central Europe to the theft carried out eleven years earlier in France. Today, Zlatka represents more than a survivor. Her story underscores how every individual matters in conserving endangered species. It also testifies to the ability of wildlife conservation professionals to locate, sometimes against all odds, animals once thought lost forever.
