Last night I was sitting in the backyard with Kilo and watched an owl make several passes over the pond. It must have been an owl. It was flying in the dark, it was big, it had raptor-type wings (I could see the silhouette against the lights in the Western sky), and each time it flew back to tree that is surrounded by a lot of owl activity evidence. This morning when we went walking, a great blue heron (and it is huge) and two ducks took off. I can't prove any of this, but it happened, and tomorrow I am planning to get up early and take pictures of them (unless they moved today - stranger things have happened).
