The InvestEGGator is used to reveal illegal trade networks and better understand what drives sea turtle egg poaching. The scientists deployed around a hundred of the fake eggs in sea turtle nests across four beaches in Costa Rica and waited. Each egg contained a GPS transmitter set to ping cell towers every hour, which would allow scientists to follow the InvestEGGator eggs on a smartphone app…Five of the deployed eggs were taken by unsuspecting poachers. The shortest route was roughly a mile, but one InvestEGGator traveled more than 80 miles, capturing what researchers were hoping for: the complete trade route, from the beach to the buyer. “Having that moment where the trade chain was complete….that was obviously a very big moment,” says Pheasey.

The InvestEGGator was the invention of Kim Williams-Guillén… The trick, says Williams-Guillén, was designing a device that looked and felt like a sea turtle egg while being precise enough to reveal trade routes. Sea turtle eggs are the size of ping pong balls, but unlike brittle chicken eggs, their shell is leathery and pliable. “Making [the trackers] look like eggs from far away was not going to be an issue, it was more making them feel like turtle eggs,” says Williams-Guillén. “One of the ways that [poachers] know that a turtle egg is good when they’re sorting their eggs is that it’s still soft and squishy.”…

Of the nests containing decoy eggs, a quarter were illegally harvested. Some of the eggs failed to connect to a GPS signal, while other eggs were spotted by poachers and tossed aside. Five of those poached eggs gave the team useful tracking data…This illegal trade network revealed that eggs are sold and consumed locally… The routes they discovered also suggest that most egg poachers in the area are individuals looking to make quick money, not an organized network.
