Animal Ethics: Oh No! Prairie Dogs Are Serial Killers!

Aww, look at the cute little prai---MY GOD, WHAT IS IT DOING TO THAT SQUIRREL???

Aww, look at the cute little prai—MY GOD, WHAT IS IT DOING TO THAT SQUIRREL???

Here’s the most troubling quote from the article in Gizmodo about a biologist’s startling discovery that prairie dogs routinely kill baby ground squirrels because they don’t like baby ground squirrels…after all, they are herbivores:

“Pop culture loves to portray herbivores as peace-loving pacifists—just look at Zootopia as the latest example of this—but who can say what other barbarous acts are going undocumented in our backyards? Are rabbits stealing into burrows to throttle chipmunks in their sleep? Do elk and buffalo lose their cool and impale each other over prairie grass? These are the sorts of unsettling questions biologists will have to start asking.”

The reason those questions will be asked is the work of biologist John Hoogland of the University of Maryland Center for Environmental Science. His observations of prairie dogs, resulting in a paper published today in the Proceedings of the Royal Society B, indicate that the cute, fuzzy mammals “will chase ground squirrels—usually babies—and if they catch them, they shake them violently. While they’re shaking, they’re biting the back of the neck to sever the vertebral column. Sometimes they grab by the head and literally debrain the baby. It’s violent, savage, and awful.”

There is a reason for this violence: ground squirrels and prairie dogs compete for the same grasses as food. It is the first known instance of a mammalian herbivore killing another mammalian herbivore on a routine basis, and Hoogland’s research indicates that it’s “just business”: the fewer ground squirrels there are; the more food there is for the prairie dogs and their young.

Clearly, prairie dog society is organized according to extreme utilitarian principles: the ends justify the means….at least when it comes to ground squirrels.

I think the ground squirrels should build a wall.
