Squirrels are a familiar sight in parks and backyards, charming us with their acrobatic leaps and nut-stashing antics. But what if these seemingly harmless creatures had a hidden, more primal side? In a stunning twist, researchers in California recently uncovered behavior that challenges everything we thought we knew about these adaptable rodents.
Instead of their usual vegetarian fare, California ground squirrels have been observed hunting live prey—a revelation that has left scientists and nature enthusiasts alike astonished. What could drive a species known for its love of seeds and fruits to suddenly develop a taste for meat? The answer may surprise you and sheds light on how animals navigate a rapidly changing world.
Squirrels Turn Predators
In a remarkable departure from their typical herbivorous habits, California ground squirrels have been observed actively hunting and consuming voles, small rodent relatives of hamsters. This unprecedented behavior was documented during the summer of 2024 in Briones Regional Park, Contra Costa County.

Squirrels Turn Predators
In a remarkable departure from their typical herbivorous habits, California ground squirrels have been observed actively hunting and consuming voles, small rodent relatives of hamsters. This unprecedented behavior was documented during the summer of 2024 in Briones Regional Park, Contra Costa County.
Researchers recorded 74 interactions between ground squirrels and voles from June to July, with 42% involving active hunting. Squirrels of all ages and sexes participated, employing various hunting strategies such as stalking, chasing, and ambushing their prey. Successful captures typically involved seizing the vole by the neck and delivering fatal bites.
This behavior coincided with a significant increase in the local vole population, suggesting that the squirrels adapted their diet in response to the abundance of prey. Lead author Jennifer E. Smith expressed astonishment at the findings, saying, “We had never seen this behavior before.” Co-researcher Dr. Sonja Wild shared this sentiment, noting, “I could barely believe my eyes… Once we started looking, we saw it everywhere.”
This discovery challenges the long-held perception of ground squirrels as strict herbivores, revealing their capacity for dietary flexibility and opportunistic feeding behaviors. The implications of this shift are profound, prompting further investigation into the ecological impact and potential prevalence of such predatory behavior among other squirrel populations.
