About a decade ago, a baker in a small mountainous village in southern Austria noticed his cow doing something unusual. When Veronika had an itch, she would grab a stick in her mouth and use it to scratch her body. Over the years, the brown bovid’s technique improved. She could pick up objects as large as a broom or rake and move them around with her prehensile tongue, changing their length and orientation to ensure the best possible scratch.
The behavior isn’t just a clever trick: It’s the first documented case of tool use in cattle, scientists report today in Current Biology. And, it turns out, one of Veronika’s skills has only been seen in humans and chimpanzees.
