That's quite brilliant. That is sheer cognitive skill and problem-solving.
There was an experiment done with crows in Japan.
They first gave them nuts over a period of time. Crows slowly got into the habit of loving nuts. Then they gave them walnuts that were hard to break. Crows starting taking them up high in the air and then dropping them to let the gravity do the job. Post that researchers gave them harder nuts, those nuts could not get broken by the free-fall of gravity.
Soon they found crows flying away with the nuts, to their amazement crows were taking the nuts to the highway and let passing vehicles destroy the nuts for them. However, this slowly also resulted in many crows getting hit by vehicles. Crows post that upped their game. They took the nuts to pedestrian crossings. Let the nuts get crushed by passing vehicles, and when the lights turned red they would gobble them up.
