Crow and mole

A European starling was making raucous comments at a crow.  The crow appeared to be pecking at something on the ground.  I figured that the crow had attacked a starling chick.  As I got closer I could see that it wasn't a chick.  It was a mole.  (I don't know why the starling was upset by a crow attacking a mole.)  As I got even closer, the crow decided that discretion was the better part of not having its meal taken away by a larger predator, picked up the mole, and flew off.
