Scientists have been forced to rethink the intelligence of cattle after an Austrian cow named Veronika displayed an impressive – and until now undocumented – knack for tool use.

Witgar Wiegele, an organic farmer and baker from a small town in Carinthia near the Italian border, keeps Veronika as a pet and noticed that she occasionally played with sticks and used them to scratch her body.

Wiegele said Veronika began playing with pieces of wood years ago, then worked out how to scratch herself with sticks. He said she also recognised family members’ voices and hurried to meet them when they called.

“I was naturally amazed by her extraordinary intelligence and thought how much we could learn from animals: patience, calmness, contentment, and gentleness,” he said.

Word soon got around and before long a video clip of the cow’s behaviour reached biologists in Vienna who specialise in animal intelligence. They immediately grasped the importance of the footage. “It was a cow using an actual tool,” said Dr Antonio Osuna Mascaró at the city’s University of Veterinary Medicine. “We got everything ready and jumped in the car to visit.”

Veronika’s home town, Nötsch im Gailtal, is “straight out of the Sound of Music” with green forests, blue lakes, mountains and a church and school near Veronika’s meadow, Osuna Mascaró said, adding: “It’s the most idyllic place imaginable for an Austrian cow.”

Armed with a deck brush, Osuna Mascaró and his colleague Alice Auersperg set about testing Veronika’s skills. Through a series of field trials, the brown Swiss proved she could not only pick up the broom, but wield it according to the job at hand. If the broom was at an awkward angle, Veronika used her tongue to reposition it before clamping it in place with her teeth.

Veronika favoured the bristled end of the broom to scratch the tough skin on her back. But she switched to the smooth handle and scratched more gently when the itch was on more delicate, lower body areas such as her udders and belly, according to the study in Current Biology.

“At the beginning I thought this was the result of a mistake. Perhaps Veronika was not careful enough when selecting her tool for self-scratching,” Osuna Mascaró said. “But after a while we started to observe a pattern: Veronika indeed had a preference for using the broom end, but when she used the handle end she was doing so in a meaningful way.”

Tool use is well known in chimps, crows, dolphins and even octopuses. The latter have been filmed throwing shells at one another. But livestock have never been considered the sharpest of animals. Gary Larson’s 1982 Far Side cartoon, Cow Tools, shows a cow standing behind a table of oddly shaped objects. It confused scores of readers, including Larson’s mother, prompting him to explain: “While I have never met a cow who could make tools, I felt sure that if I did, they (the tools) would lack something in sophistication and resemble the sorry specimens shown.”

Veronika is far from making even misshapen tools, but her prowess in using them has impressed nonetheless. Over seven sessions of 10 trials, the researchers witnessed 76 instances of tool use as she grabbed the broom to scratch otherwise unreachable regions. Using both ends of the brush counts as multi-purpose tool use, the scientists say, which is extraordinarily rare. Beyond humans, it has only been shown convincingly in chimpanzees.

It is unclear how Veronika acquired her skills, but circumstances have been in her favour. Few cows reach her age of 13 years old, or live in such a stimulating environment. That said, the researchers believe cattle may simply be smarter than people have previously realised. Since the study, Osuna Mascaró said other clever cows have come to light. “We don’t believe that Veronika is the Einstein of cows,” he said.

“What this tells us is that cows have the potential to innovate tool use, and we have ignored this fact for thousands of years,” he added. “It’s shocking that we’re only discovering this now.”

There is no suggestion that Veronika’s skills are evidence of the evolution of an ominous new species of super-cow. As the scientists write in the study: “She did not fashion tools like the cow in Gary Larson’s cartoon, but she selected, adjusted and used one with notable dexterity and flexibility. Perhaps the real absurdity lies not in imagining a tool-using cow, but in assuming such a thing could never exist.”
