Indeed, the Corvid family (crows, ravens) has been show to do some pretty complex problem-solving. I imagine that occupying a high perch out of danger and watching the goings-about by many creatures below, it helps to have a brain that figures out the behaviors of other animals, like squirrels, foxes, etc. That's a really theory-of-mind activity; modeling the thoughts of other animals (and the information available to each) to predict their behavior.
