Ravens can imagine being spied upon by a hidden competitor, showing a capacity for abstraction once thought to be exclusively human, according to a new study.
Scientists have shown that the birds take extra care to hide food if they suspect their movements are being monitored by another raven, even when the second bird is not actually there.
The findings, published on Tuesday in the journal Nature Communications, suggest that ravens – without recourse to direct observation – are able to understand what might be going on in the mind of another individual.
“This shows that traits that we consider uniquely human may be found in animals too,” said the lead author of the study, Thomas Bugnyar, a professor at the University of Vienna and an expert on social cognition in animals.
