Cows are not usually credited with thinking on the hoof. They eat, they chew, they stand in fields performing an activity that may look like contemplation but is generally written off as digestion.
They are not typically thought to plan, let alone solve problems. A new study suggests we may have underestimated them.
The research describes what experts claim is the first documented case of flexible, multi-purpose tool use in cattle, observed in a cow named Veronika.
...
Veronika is a Swiss brown cow kept not for milk or meat but as a pet by Witgar Wiegele, an organic farmer and baker in Austria. More than a decade ago he noticed her using a long-handled brush, holding it in her mouth to scratch awkward parts of her body.
When video footage of this behaviour reached Alice Auersperg, a cognitive biologist at the University of Veterinary Medicine, Vienna, it struck her as unusual, largely because Veronika used the brush in different ways to scratch different parts of her body.
“It was immediately clear that this was not accidental,” Auersperg said. “This was a meaningful example of tool use in a species that is rarely considered from a cognitive perspective.”
Auersperg and her colleague Antonio Osuna-Mascaró conducted a series of trials. They placed a long-handled brush on the ground and recorded how Veronika used it.

When scratching broad, thick-skinned regions such as her back or rump, Veronika tended to use the bristled end, applying it with sweeping, forceful movements. When targeting softer, more sensitive areas of her lower body, she switched to using the handle to scratch herself, moving more slowly.
Because Veronika directs tools at her own body, researchers describe this as egocentric tool use, which is usually regarded as less complex than tool use aimed at external objects. Even so, flexible, multi-purpose use of a single tool is rare. Outside humans, it has previously been demonstrated convincingly only in chimpanzees, the researchers say in their paper.
They wrote in a study published in the journal Current Biology that the findings “invite a reassessment of livestock cognition”.

The researchers suspect that Veronika’s life circumstances have played a role in the emergence of this behaviour. Most cows do not reach her age and they are rarely given the opportunity to interact with a variety of potentially useful objects.
Her long lifespan, daily contact with humans, and access to a rich physical landscape probably created favorable conditions, they said. If that is true, there may be nothing very exceptional about Veronika, other than the opportunities she has been given to exercise her brain.

By Kevin Harris and Richard McDaniel (TriceEdneyWire.com)—Democrats ended 2025 with important victories that steadied a rattled party still reeling from Donald Trump’s return to power. Yet even after those wins, Democratic approval ratings remain stubbornly low. A recent Quinnipiac University poll found only 18 percent of voters approve of the way congressional Democrats are handling […]The post
