Urban birds have discovered a special advantage compared to life in the wild – Video: BBC Wildlife
Through many years of development, cars are no longer just a simple means of transportation. Today, cars can become sources of electricity, mobile homes, kitchens… and crows have found another use: grain crushers.
Strange story but absolutely true. In Japan, birds drop walnuts on the road so that passing cars can peel the walnuts for them.
This adorable wild behavior was captured in a British nature documentary, which follows crows practicing their survival skills.
The filmmakers could not have imagined that crows would drop walnuts on the road, waiting for passing cars to crush the difficult-to-shell walnut shells for them.
So how can they swoop in to get the spilled seeds when the risk of being hit by a car is too great? These clever little creatures have discovered one place where cars don’t always rumble: pedestrian crossings.
Famous British biologist Sir David Attenborough explains gently in the video: Some birds have developed a “seed peeling industry” by dropping seeds at pedestrian crossings.
When crossing a suitable road, the birds drop seeds during the green light, then wait for the red light to fade to get the peeled seeds.
Humans have tools for peeling walnuts, but it seems birds are smarter at it. At the very least, the tools they use are more modern than any peeling pliers.
