In a Japanese city, this crow was unable to eat the nut as it has a hard shell. So he dropped it on the hard surface of the road which broke it. But it had fear of coming under the oncoming traffic.

In order to survive, it obeyed the simple traffic lights (which it had no idea about) and dropped the nut on the pedestrian crossing line aka zebra crossing. As the cars ran over the nut making small pieces of it, he goes and eats those pieces when the traffic gets halted on a red light.

This footage is captured by BBC team and narrated by none other than Sir David Attenborough.
