Squirrels Observed Hunting Mice: A Surprising Behavioral Discovery
Researchers have observed California ground squirrels, commonly known for their herbivorous diet of nuts and seeds, hunting and eating mice. This surprising behavior, indicating an aggressive side to these seemingly docile animals, was recently documented in a study published in the Journal of Animal Behavior .
