One of the best bird shows I ever saw happened a few years ago in the fall. Two crows were pestering a great horned owl all morning. Later in the day the owl set down a long branch of an old tree on the hillside. One of the crows plopped down at the end of the branch and would periodically step a little closer and squauk. After ~10min the owl took one big hop, swung that great big left wing and smacked that crow for a home run. It tumbled so fast that old crow didn't know which way was up and he banged right into the hillside. He shook it off and flew away never looking back...and the owl just sat there for the rest of the afternoon.
