Cawing gull. About 2 minutes before I took this picture, I ran into some people who reported several large hawks diving at each other. I hurried to the spot and found nothing except this lone, seemingly-upset, gull. Had there been hawks? Had the people correctly identified the birds as hawks? I think, yes, to both questions. Gulls, in my observations, often travel in groups at a leisurely pace. This gull circled frantically and then flew on. At the same time I saw the gull, I heard, but never saw, a loud Kiskadee with its call, which sounds like its name. So, what was going on? Something. It begs the question, if a tree falls in the forest and no one sees it, does it really fall? Increasingly, I think reality is more about the observer and the observation point than it is about an objective set (of facts, vertices, etc.) that exists in space/time.
