Florida deploys robotic rabbits to combat invasive pythons

Florida’s Everglades, a unique and fragile ecosystem, is facing a serious threat from invasive Burmese pythons. These non-native snakes have devastated wildlife populations of small mammals and birds. In Everglades National Park, authorities estimate that 95% of small mammals and thousands of birds have been eliminated, leaving a significant ecological imbalance.

Experts highlight the challenge

Mike Kirkland, invasive animal biologist for the South Florida Water Management District, highlighted the difficulty of managing the python population:

“Removing them is fairly simple. It's detection. We're having a really hard time finding them. They're so well camouflaged in the field.”


In an inventive approach, scientists have deployed robotic rabbits to lure pythons into view and out of hiding. These devices have been enhanced to mimic real marsh rabbits. They emit heat, produce scents, and move naturally to replicate live prey. “They look like a real rabbit,” Kirkland mentioned.

How the technology works

The solar-powered and remotely operated robotic rabbits can be activated and placed in small pens monitored by video cameras. When a python approaches, the cameras send alerts to researchers, enabling them to act rapidly.

“Then I can deploy one of our many contractors to go out and remove the python,” Kirkland explained.

Each robotic rabbit costs roughly around $4,000, fully funded by the South Florida Water Management District. Ron Bergeron, a member of the district’s governing board, highlighted the importance of the initiative:

"Every invasive python that is removed makes a difference for Florida's environment and its native wildlife."

Kirkland noted. “This part of the project is in its infancy. We are confident, though, that this will work once we are given enough time to work out some of these details.”

Pythons’ origins and reproduction

Burmese pythons are not native to Florida. Over the years, escapes and intentional releases of pet snakes have enabled them to establish breeding populations in the Everglades. Female pythons can lay between 50 and 100 eggs at a time, complicating control efforts particularly challenging.

Estimates of the numbers are difficult to determine as they vary widely. The U.S. Geological Survey cites that the population is in the “tens of thousands,” while other authorities mention as many as 300,000 snakes. Since 2000, more than 23,000 pythons have been removed from the wild. Adult pythons can grow between 10 and 16 feet (3 to 5 meters) in length, making them formidable predators. Their size and camouflage and elusive behavior make detection a real challenge, which the robotic rabbit program focuses to address.
