Perhaps “birdbrained” isn’t such an insult after all –– crows, the ubiquitous urban bird, can vocally count up to four, the latest research has found.
Not only can the inquisitive creatures count, but they can match the number of calls they make when shown a numeral, according to a new study.
It was led by a team of researchers with the University of Tübingen’s animal physiology lab in Germany.
The way the birds recognize and react to numbers is similar to a process we humans use, both to learn to count as toddlers and quickly recognize how many objects we’re looking at.
The findings, published Thursday in the journal Science, deepen our growing understanding of crow intelligence. (CNN)
