A group of California squirrels—long thought to be nut-hoarding vegetarians—have evolved into carnivorous predators, according to a groundbreaking study.
Scientists documented California ground squirrels hunting and consuming live voles in the first-ever recorded instance of the species displaying carnivorous behavior. The research, published Wednesday in the Journal of Ethology, was conducted as part of the Long-Term Behavioral Ecology of California Ground Squirrels Project in Briones Regional Park, Northern California.
