Exact thing happened to me one or two days ago. I was driving home and on a small street near my apartment a crow flew out of the bushes and dropped something right in front of the car and then it landed on the other side of the street. When I looked back in the mirror, the crow had gone back to collect what looked like a walnut.
On a semi-related note, magpies are also doing really well in that race. End of last year I started leaving oatmeal in a bottle cap on my terrace and every morning a magpie came to eat it every single day over the course of 2 months. And every evening when I came back home I had a handful of sticks, stones and berries left somewhere. No idea what I was supposed to do with them but thanks magpie I guess...
