Driving to work today, I noticed a crow down the street taking off from a telephone wire. He hovered for a few seconds in the air until my car neared him, and then he dropped something right in front of me. I heard a crunch as one of my tires ran over it. In my rear view mirror I saw the crow land on the street after I'd passed.
I've heard that crows have learned to use cars to crack their nuts for them, but this is the first time I've had the honor of being selected for the task!
