Actually Joel, I have been admiring even what I consider to be subtleties of your set up. For example, I have a longish stick mounted to the vertical rod of the bird feeder. My issue, I never know what part of the stick they are going to land on. Probably 70% of the time when they do land on it, I do not even get a shot off as I by the time I recompose slightly, they've already jumped to my feeder. Also, I am impressed by how many birds notice my even slight movements. The female cardinal in particular does not like it.
But, your current set up, a nice point. Subtle, but I am already thinking of how to incorporate it into my set up.
