Crows use cars to open nuts!
Crows are known to be some of the smartest animals around. There are a lot of examples of their intelligence, but this one is pretty nifty. Crows in urban areas have learned that they don’t need to work hard to crack open nuts when they want to eat them.
Instead, what they do is they wait for the traffic light to turn red, and they go place nuts in front of cars. When the cars pass by, the weight cracks the nuts open and then they wait for the light to change again and collect their reward. Nifty!
