PRAIRIE DOG

Con Slobodchikoff, a biologist and a professor emeritus at the University of Arizona, has studied prairie dogs for 30 years. He started studying the animals after it was reported that ground squirrels made certain sounds to warn each other of flying predators, and different sounds they'd make to warn of ground predators - their own language, basically.
"They're able to describe the color of clothes the humans are wearing, they're able to describe the size and shape of humans, even, amazingly, whether a human once appeared with a gun".
