Justice for Far Side cartoonist Gary Larson: A team of scientists has observed, for the first time, a cow using a tool in a flexible manner. The ingenuity of “Veronika,” as the animal is called, shows that cattle possess enough intelligence to manipulate elements of their environment and solve challenges they would otherwise be unable to overcome.
Veronika is a pet cow in Austria. Her owners don’t use her for meat or milk production. Nor was she trained to do tricks; on the contrary, for the past 10 years she has developed the ability to find branches in the grass, choose one, hold it with her mouth, and scratch herself with it to relieve skin irritation.
Until now, only chimpanzees had convincingly demonstrated the ability to employ tools to improve their living conditions. Recent studies also point to whales as the only marine animals capable of using complex tools. This European cow is about to join that exclusive group of ingenious animals.
Videos of Veronika circulating online caught the attention of veterinary researchers in Vienna. They visited the farm, conducted behavioral tests, and carried out controlled trials. “In repeated sessions, they verified that her decisions were consistent and functionally appropriate,” a press release stated.
Veronika’s abilities go beyond simply using a point to scratch herself, explain the authors of the study published in Current Biology. In the tests, the cow was offered different textures and objects, and she adapted according to her needs. Sometimes she chose soft bristles and other times a stiffer point. The researchers say she used different parts of the same tool for specific purposes and even modified her technique depending on the type of object or the area of her body she wanted to scratch.
Although they consider using a tool to relieve irritation “less complex” compared to, for example, using a sharp rock to access seeds, the specialists greatly value Veronika’s ability. For now, she demonstrates that she can decide which part of the tool is most useful to her. The finding suggests that we have underestimated the cognitive capacity of cattle, according to the authors.
Why Is Veronika So Skilled?
The team acknowledges that it’s still too early to say that all cows can use tools with the same skill as Veronika. For now, the researchers are trying to determine how this cow developed an awareness of her surroundings.
Researchers believe her particular circumstances played a role. Veronika has lived for 10 years in a complex, open environment filled with manipulable objects—a very different experience from that of cattle raised for milk and meat production. These conditions fostered exploratory and innovative behavior, they say. They are now searching for more videos of cattle using tools to gather further evidence about their cognitive abilities.
“Until now, tool use was considered a select club, almost exclusively for primates (especially great apes, but also macaques and capuchins), some birds like corvids and parrots, and marine mammals like dolphins. Finding it in a cow is a fascinating example of convergent evolution: intelligence arises as a response to similar problems, regardless of how different the animal’s ‘design’ may be,” said Miquel Llorente, director of the Department of Psychology at the University of Girona, who was not involved in the study, in a statement to the Science Media Centre Spain.
