I wonder whether it was discovered independently, or if it has been communicated somehow. Or maybe they've "always" done this, except with horses before cars.
- flohofwoe 11y agoAmazing. In Berlin, the crows are mostly grey 'hooded crows' (Nebelkraehe in German), they seem to have displaced the pigeons that were common 5 to 10 years ago.
- kaybe 11y agoWhen there are no cars, the strategy is to simply drop them from high onto a hard surface (such as a road). They always fly off with their nuts when I try to help though..
- steveax 11y agoLots of crows and walnut trees in my 'hood. When I see a crow drop a nut into the street when I'm out and about, I walk over and crush it. I'm hoping someday they'll recognize me and start dropping near me when I'm walking :-)
- sandworm101 11y agoIt isn't new. It's probably older than man. Birds drop seashells onto rocks to break them open, something you don't need roads for. Car's parked at my local dog beach are constantly under attack from mussel-wielding crows. But placing the shells on the road for the cars to squash. That's new.
