Fascinating. I love that shot of the redpoll. Such a gorgeous splash of color. Once in while when one or two would land to feed, then briefly leave and return a minute later with a whole flock of a hundred or more. Fun to watch. When they'd all leave, always just one, I assumed the same one that called the flock in, would stay perched on the turned bucket I had on the trunk. Interesting how nature can be so complex yet so simple to observe at the same time.
