Veronika has the ability to control the
tool depending upon what location she wishes to scratch, the researchers found.

“People tend to think that anything an animal does with an object is tool use and sometimes you get sent videos of animals randomly interacting with objects, like ‘My cat is using a tool because she’s using my Amazon box as a house.’ But this particular video was different,” Auersperg informed Live Science. “It showed the kind of a behavior I would expect from the stricter definitions of tool use, where you see a tool is an embodied part of the animal and it is used as a direct elongation of her body.”After seeing the video, Auersperg and her coworker, Antonio Osuna-Mascaróan animal cognition scientist likewise at the University of Veterinary Medicine, set out to fulfill Veronika and put her to the test. They consistently positioned a deck brush, or broom, on the ground in front of her in a random orientation to see what she would do.
“We decided to use a broom because a broom has a functional end and a non-functional end. So our prediction was that if Veronika is really sensitive to the functional properties of the tool, she will prefer to use the broom end,” Osuna-Mascaró informed Live Science.
Veronika got the things by the manage end and scratched herself with the broom end about 2.5 times regularly than doing it the other method round, he stated. After a while, a more nuanced pattern emerged.

Veronika began utilizing tools to scratch herself about 9 years back. (Image credit: Antonio J. Osuna Mascaró)After 70 sessions, if Veronika was going to scratch the thick skin of her back, she normally got the broom in her mouth by the thin end and offered herself a great extensive scratch with the huge, abrasive brush. If she wished to scratch a more fragile location, like her navel or udder, she would get the broom by the brush end and rub herself carefully with the thin manage.
The research study was released in Existing Biology on Monday(Jan. 19 ).
Veronika’s habits likewise showed that she understood which body part she planned to scratch before getting the broom, instead of simply utilizing a tool in whatever orientation she occurred to select it up, Osuna-Mascaró stated.
She would raise her tail in anticipation when she was going to scratch her fragile anal area and adjust her grip on the tool to guarantee she might reach it, he stated.
The readjustment was no simple matter. To get the brush, Veronika would present her tongue, cover it around the tool, bring it as much as her mouth and press it in between her lower teeth and the tough oral pad at the top of her mouth, stated Auersperg. This indicates the tool sits there extremely strongly and can’t be quickly changed. Often, Veronika would release the tool before scratching, then get it once again in a various location and after that direct the tool at the body area that she would not have actually had the ability to reach with the previous grip.
This habits is really various from a cow simply utilizing a scratching pad, Auersperg stated. Scratching yourself versus something is simply an interaction in between an animal and a things. To certify as tool usage, the animal needs to be accountable for the orientation of the item, as Veronika is.
“I have absolutely no doubt that this is tool use,” Josep Calla relative psychologist at the University of St Andrews in Scotland, who wasn’t associated with the research study, informed Live Science. “They clearly show that the cow uses the brush, the one end or the other, depending on the area that it is scratching. That’s very nice.”
Gloria Sabbatinian animal biologist at the National Research Council of Italy’s Unit of Cognitive Primatology and Primate Center in Rome, who wasn’t associated with the research study, concurs.
“Veronika shows an egocentric form of tool use, that is the use of a tool toward herself. This kind of tool use is simpler than tool use toward an external object or surface for many reasons,” she informed Live Science by means of e-mail. “One is that she directly perceives the effects of tool using on herself and then she can quickly correct and modify the position of the tool.”
Scientists think Veronika’s tool usage is the outcome of her being a household animal and having challenge
engage with.

The habits can be partially described by the reality that Veronika is kept as a household animal. She experiences various meadows and stables in the winter season, and numerous items fall under the meadow for her to communicate with.
“Veronika was lucky to have the possibility to experience a day-a-day reality more complex and stimulating than the one usually offered to cows. Through the daily interaction between mind, body and environment, animals develop and improve their abilities and skills,” Sabbatini stated.
It does not indicate this is a one-off. Osuna-Mascaró has actually likewise determined videos on social networks of a Brahman bull (Bos indicus utilizing a stay with scratch an itch
Considered that the 2 types diverged more than 500,000 years back and have actually been independently domesticated because, Osuna-Mascaró recommended that Veronica is revealing a hidden ability for development that might have remained in livestock for countless years.
“We do not mean that ancient oxen were tool users, but that these animals have the capacity to innovate spontaneous solutions to complex problems,” Auersperg stated. “When they are little, cows play with objects, they love playing with balls, with ropes and also with sticks. So, if they have a rich environment, perhaps they will show these innovations more often.”
