Prairie dogs may be gossiping about you. Researchers say their calls describe size, shape and clothing. 🐾
When a prairie dog spots a predator, it sounds an alarm. But biologist Con Slobodchikoff of Northern Arizona University spent decades studying those calls and found they carry more than “danger.” They can name the kind of predator, such as a hawk, coyote, dog or human, and describe its size and shape. In tests, the calls even changed with the color of a person’s shirt.
Most of that research was done on Gunnison’s prairie dogs, a relative of the black-tailed prairie dogs at the Wichita Mountains Wildlife Refuge. Black-tailed prairie dogs have their own system of twelve distinct calls, and they also keep a lookout so the whole colony can dive for cover.
Whether that counts as a true language is still debated among scientists. But next time you walk past a prairie dog, remember that someone may be keeping notes on what you’re wearing.
