In middle Europe, crows have learnt a new way to open nuts they can't crack with their beak.Usually they take the nuts, fly very high and drop them onto stones (e.g. sidewalk). This doesn't work well and is very energy intensive.
Now they take the nuts and drop them onto crosswalks and then wait sitting on the traffic light. When the pedestrian light turns green, they collect the nuts whcih were crushed by passing cars.
I've seen this several times in Cologne and Bonn.
Corvids are smart birds and some are capable f making their own tools.

there was an article somebody brought up somewhere I frequent that said some australian birds had been caught using burning sticks from bush fires to strategically spread the fire to herd small prey animals out into the open. I forget at the moment whether it was crows, or a small breed of raptor.
