But I’ve watched prairie dogs before, and it doesn’t seem like they’ve got a lot going on. What do they even have to talk about?
My assumption would be that they mostly focus on how other prairie dogs would look dressed up in tiny clothes, and what sort of clothes they might wear, and if male prairie dogs would have to wear suits and female prairie dogs would have to wear dresses, or if any prairie dog would be allowed to wear a suit or a dress.
The scientist, who has been studying prairie dogs for thirty years, says that the rodents have developed their sophisticated “bark” to warn the other members of their colonies about the specific details of approaching predators. The tiny sonic variations of each bark can contain information about what sort of animal is approaching, what color it is, and from which direction it’s coming.
Prairie dogs react to different predator species in different ways. For something like a coyote, they will retreat to the mouth of their burrows and stand up to watch the approaching animal. For a badger, on the other hand, they will “lie low to avoid detection.”
To test his hypothesis about the complexity of prairie dog barks, the scientist recorded barks associated with different predators in a variety of situations, and then observed the behavior of all the members of the colony after the bark was heard. He then replayed those recordings to other prairie dogs when there were no actual predators nearby, and found that they reacted in precisely the same way as the threatened animals.
It’s like if an axe murderer burst into a crowded gymnasium. Someone might shout, “Run! There’s an axe murderer at the door!” and everyone would run away from the door and try to get behind something axe-proof. If, then, you were to shout, “Run! There’s an axe murderer at the door!” into a crowded (but murderer-less) gymnasium, people might still run away from the door to get behind something axe-proof because of the specific information in the warning. It would be a different reaction than if you were to just scream, or if you shouted that acid was raining from the ceiling, or that the world’s biggest clown had was digging up through the floor.
It’s sort of the same with prairie dogs, really.
