California ground squirrels hunt, kill and eat voles, reveals a study by UC Davis and UW-Eau Claire, sharing the first evidence of widespread carnivorous behavior among squirrels.

A ground squirrel with cheeks stuffed with nuts, seeds or grains, is a common sight. But a new study provides the first evidence that California ground squirrels also hunt, kill and eat voles. The study, led by the University of Wisconsin-Eau Claire and the University of California, Davis, is the first to chronicle widespread carnivorous behavior among squirrels.

      Right! But, if you zoom out, it’s not exactly too wild. Ground squirrels have voles beat in size and they have habitat overlap with both living underground. Additionally, dietary shifts give animals the flexibly to respond to changes in the environment plus foraging risks and opportunities. It’s been known since the early 2000’s that squirrels can supplement some of their diet with insects or bird eggs/baby birds. Knowing this, it starts to make a lot more sense ground squirrels would hunt voles, as the environment is rapidly changing, they’re known to already hunt a bit, and voles could be their annoying neighbor.
