Mary the Devil: How One Marsupial Outsmarted a Thermal-Imaging Drone

When keepers at Paradise Country wildlife park discovered their two-year-old Tasmanian devil named Mary was missing from her enclosure on Tuesday morning, they probably figured recapturing her would be a straightforward operation. They had thermal-imaging drones, sniffer dogs, and a dozen wildlife experts ready to go. What they didn’t account for was Mary’s determination to stay hidden.

By Thursday—her third day at large—Mary was still eluding every search tactic the team threw at her. CCTV footage showed her bolting into the darkness of the park’s grounds on Queensland’s Gold Coast several hours before anyone even realized she was gone, but that head start proved to be all she needed. For a small, shy marsupial, Mary’s escape and subsequent Houdini act is actually pretty remarkable. Park curator Lauren Mousley described her as extremely shy and unusually adventurous for her age, making the breakout itself“very, very abnormal given her demeanour.”

What makes Mary’s situation particularly interesting is what she represents. Tasmanian devils have been extinct on mainland Australia for more than 3,000 years, and the species faces serious conservation challenges back home in Tasmania. They’re listed as endangered and threatened by Devil Facial Tumour Disease, a rare transmissible cancer that spreads through the population. Every individual animal matters. Mary might be relatively young at two years old, but she’s part of efforts to maintain genetic diversity and population stability—which is exactly why park officials were so determined to find her.

The irony here is almost poetic: a marsupial species that can roam up to 16 kilometres in a single night, armed with nocturnal instincts honed by thousands of years of evolution, proved far more elusive than modern search technology could handle. Despite her young age and generally timid nature, Mary tapped into something primal when she made her break. The wildlife park’s priority remains on relocating her safely, but as of the article’s publication, she remained at large—a small, furry reminder that nature, when given the chance, will always outsmart our best-laid plans.
