Tai-Chi Vesper

We stopped at the National bison Range on our way to Yellowstone and the Vesper Sparrows were there in force. Toward the end of our circuit we ran into a couple of cooperative ones. I think this is a female, but only because the males seemed to be singing constantly and we watched this one for quite some time without it doing so. This pose was actually in preparation for a good chin scratch, though why it swung its leg to the rear first, I don't know.
