The findings, published Thursday in the journal Science, deepen our growing understanding of crow intelligence.“Humans do not have a monopoly on skills such as numerical thinking, abstraction, tool manufacture, and planning ahead,” said animal cognition expert Heather Williams via email. “No one should be surprised that crows are ‘smart.’” Williams, a professor of biology at Williams College in Massachusetts, was not involved in the study.In the animal kingdom, counting isn’t limited to crows. Chimpanzees have been taught to count in numerical order and understand the value of numerals, much like young children. In attempting to woo mates, some male frogs count the number of calls from competing males to match or even one-up that number when it’s their turn to croak at a female. Scientists have even theorized that ants retrace their paths back to their colonies by counting their steps, though the method isn’t always accurate.What this latest study showed is that crows, like young humans, can learn to associate numerals with values –– an …
