Prairie Dog, UtahPrairie dogs are highly social and live in large underground colonies (or “towns”) with intricate tunnel systems and designated rooms for sleeping, nursing, and even waste (how about that fact — these guys actually have bathrooms). They also have one of the most sophisticated vocal communication systems in the animal kingdom, using different barks and chirps to warn each other of specific predators, including details like type, size, and direction. Who knows what description this guy was giving the rest of the town about the large man crawling in the bushes, interrupting lunch.
