I was just outside, and there were two male robins having what I can only assume was a territorial disagreement. It was amusing to watch them chasing each other through the two maples in my back yard…….it got un-amusing very quickly, however. They began chasing each other to the rhododendron beside my back door, back to the trees, back and forth, I happened to be in the flight path so I ducked…….just as the pursuing bird dropped his flight to attempt a takeover from below. SMACK! Ouch. Right into the side of my head.
