Crows are able to vocally count up to four and match the number of calls they make when shown a numeral, similar to how humans learn to count. This research deepens our understanding of crow intelligence and challenges the belief that all animals are merely stimulus-response machines.
Key Points
Crows can learn to associate numerals with values and count accordingly
They plan the number of calls they will make before vocalizing
Crows' mistakes in counting are advanced and show similarities to human errors
Research challenges the idea that all animals are stimulus-response machines
Pros
Deepens understanding of crow intelligence
Challenges previous beliefs about animals' decision-making abilities
Shows crows can plan ahead and communicate in a structured way
