Kinglets flit. Trying to get a picture is as tricky as trying to capture a hummingbird. The ruby crowned kinglet will flash bright red as did the Saturday kinglet, but yesterday they were only interested in eating. Bugs. I could happily watch kinglets all day, .... think half the size of a sparrow. And when they sing it's heaven. Then don't take pictures, just listen. Trying to get kinglet pictures is a very good test of one's reflexes.
