Now I forget who i was talking to about corvids :-( They are crazy smart. Check out this experiment https://hooktube.com/watch?v=Gui3IswQ0DI a crow takes 8 steps to solve a puzzle.
One day I tossed some salted peanuts to some crows. They took them to a puddle to wash them off.
I started buying unsalted peanuts just for the crows.
Pretty soon they knew my car.
