Cow tool use prompts scientists to reassess cattle intelligence

An Austrian Brown Swiss cow named Veronika was observed using a broom to scratch different body areas, and researchers recorded 76 instances of purposeful tool use during field trials reported in Current Biology.

An Austrian Brown Swiss cow named Veronika has been documented using a broom to scratch different parts of her body. The behaviour was first noticed by her owner, farmer Witgar Wiegele, and later brought to the attention of researchers from the University of Veterinary Medicine Vienna. Scientists conducted field trials and recorded repeated, targeted use of the brush. The observation has led researchers to discuss whether cattle intelligence has been underestimated. Key observations: - Veronika was recorded using a deck brush in seven sessions of 10 trials, with researchers documenting 76 instances of tool use. - She used the bristled end to reach and scratch tougher skin on her back and the smooth handle to scratch more delicate lower areas such as her belly and udders. - When the broom was awkwardly positioned, she used her tongue to reposition it before holding it with her teeth. - The work was conducted by researchers including Dr Antonio Osuna Mascaró and Alice Auersperg and is reported in the journal Current Biology. - Veronika is about 13 years old and lives in a stimulating environment; researchers have noted other examples of clever cows since the study. Summary: Researchers report that Veronika selected, adjusted and used a tool with notable dexterity, a pattern that has prompted reconsideration of cattle cognitive abilities. Undetermined at this time.
