It was a waxing moon, about half-full, so the moon was up but not overly bright. I had gone to bed about 10 pm, loathing daylight savings time and the fact that I wasn't really tired yet. About 15 minutes later, I noticed a couple of things: First, the house seemed to creak in several places at once, although I felt nothing unusual. Second, every bird in the countryside started singing. It was the Dawn Chorus at night. They were so loud, and it was so unusual, that I went and got Big Ag, who had been watching television in another part of the house, and brought him to the back door so he could hear it too.
This went on for an hour or two, and then, just like that, it stopped. And the night was as quiet as it normally is.
This morning I awoke to see this:
Yes, the shaking apparently started at about 10:15 pm last night. Guess our neighborhood songbirds know more than you'd think.
