Wrentit, agitato

During a bird survey today I was walking along, minding my own business, when I heard the strangest sound coming from the bush. I looked inside, and there was a very agitated wrentit who then jumped out of the bush to give me a stern talking to. I was at a loss for a reaction. Do I carry on? Apologize? Or fuss back? 
He — or she — didn't give me a chance to reply. He flew off as soon as he said his mind.
