I headed off to another location to see what was going on. What was going on were bugs and seeds. I've seen termite hatch-outs. Termites are big. This time I saw tiny insects hatching. It seemed very weird since it was so cold, but they were hatching from dead wood, teensy insects, thousands of them, and the only birds showing interest in them were the white-throated sparrows. The cardinal was interested in nuts.
