Saw this on YouTube - it is a David Attenborough piece on urban Crows in Tokyo and how they have learned to drop nuts from wires into pedestrian crosswalks. They let the cars crush the nuts, then wait for the pedestrians to begin crossing to fly down and eat the nut before the light changes. Pretty cool!

Out here in the "Western U.S." Brewer's Blackbirds and Stellar's Jays both 'Hunt' the grilles--- or (front ends) of cars in parking areas for "Stuck On" bugs. One fills a lowland nitche, one - the uplands. Evolution...........

They are clever, these corvids!!! Quite complex thinking evident here, they have to plan ahead and then wait, delayed gratification, for the safe time to reap the rewards of their efforts. Very impressive.
