Uinta ground squirrels at Tower Fall Campground in Yellowstone National Park, Wyoming

Though there are no known incidents of Uinta ground squirrels breaking out in four-part harmony, they have a repertoire of calls. Chirps signal an airborne predator nearby. Trills indicate a ground predator, such as a long-tailed weasel. Aside from all this chatter, they’re not terribly social with each other outside mating season.
