yesterday this bird showed up. I believe that it is a sparrowhawk. I was so frightened. He stayed 5 seconds but 15 minutes after he left I heard a horrible sound of fight. I heard his voice and what sounded as my jays. Did they fight him? Did he kill another bird? I do not know. I didn’t see him today and the little birds and squirrels were all over the place eating their peanuts and nuts. I ordered a balloon that is supposed to scare the sparrowhawk away. I will see what I can do to make my restaurant more secure against such a catastrophic predator.
