Turkey cat funeral explained

This video of turkeys circling a dead cat went viral yesterday...https://twitter.com/TheReal_JDavis/status/837301561500057605... and here's the explainer, from The Verge's Alessandra Potenza and Rachel Becker. They're a) warily inspecting a potential predator they don't realize is dead while b) getting stuck in a natural follow-the-leader pattern.

predator inspection, says Alan Krakauer, a biologist at the University of California, Davis, who studies the behavioral ecology of birds, in an email to The Verge. Sometimes, animals lower down in the food chain approach predators a behavior that can be seen as risky, but can actually help the prey. Making the predator aware that the prey know its there can sometimes scare the predator away. ... What could be happening is that the turkeys are stuck in some kind of never-ending circle, with each bird following the tail in front of it. Its not unusual for them to get into those dances where they chase each other around, Scott Gardner, a turkey expert with the California Department of Fish and Wildlife, tells The Verge.
