Yet another example of intelligence from the New Caledonian crow.
A favourite for researchers, New Caledonian crows have shown that they can make functioning tools out of different constituent parts. Moreover, they had to figure out how to join the bits together themselves. They did not have a crib sheet, nor did they have any training. They only had the lure of a treat at the end if they were successful. This is high-end animal tool making. If only AI could do that. If you have any difficulty putting together your latest Ikea purchase, ask a crow to do it for you.
