Squirrels are often seen as harmless animals, scampering about parks or trees, munching on nuts and seeds.
But new research suggests we may need to rethink this perception.
Chipmunks and ground squirrels, known for their opportunistic feeding habits, have been observed actively hunting other animals in ways that shocked scientists.
American researchers have documented cases of California ground squirrels hunting and eating other wild animals, writes Videnskab.
These findings come from observations in Briones Regional Park, California, during June and July.
Researchers recorded 74 interactions between the squirrels and voles. In nearly half of these cases, the squirrels were actively chasing and killing the small rodents.
Sonja Wild, a postdoc at the University of California and lead author of the study, described the behavior as surprising.
She explained that they witnessed attacks that included surprise ambushes, neck bites, and violent shaking of prey.
Such behavior is not unheard of, as squirrels are opportunistic eaters, but actively hunting other mammals was unexpected.
Ground squirrels have been seen consuming meat before, including birds and fish. However, this new study reveals a more predatory side to the species.
The researchers believe this adaptation might be linked to environmental changes.
As climate change and habitat loss force animals to alter their behaviors, the ability to diversify feeding strategies could be crucial for survival.
Wild and her team view this development as a positive sign of adaptability. She noted that while the behavior may seem unsettling, it shows that these squirrels are capable of surviving in changing environments.
The findings suggest that animals can modify their diets and strategies to cope with ecological challenges.
This discovery offers a fascinating glimpse into the complex behavior of wildlife. It reminds us that even familiar creatures like squirrels have hidden sides we are only beginning to understand.
As ecosystems shift, studies like this show how animals adapt in ways that may surprise and intrigue us.
