Guest guest Posted June 27, 2008 Report Share Posted June 27, 2008 Hello, a little off topic and preaching to the choir too, but often here appear animal tales so here we go. I just heard this on Polish public radio, an interview with a biologist at the Warsaw zoo (by the way, I think zoos are a terrible invention, and should be only used for endangered species), about crows in Warsaw. He observed, how city crows use ingenious methods to crack walnuts. For example, they will put the walnut under a tire of a car standing at a red light, and the car rolls over, the crow collects the cracked walnut. Recently he saw a car that rolled a little and stopped again, right over the walnut - the crow flew in, looked at the tire, saw the walnut was underneath, looked up at the driver with a sideways glance, stepped back a little waited for the driver to start again.
