Clay-colored Sparrow?

Suzette, Jane, and I spent a few minutes studying a sparrow in the bushes between the lower garden and the wildflower field. I had a hard time with it. Now that I've had a chance to collect my thoughts, I think it was a Clay-colored Sparrow. It was an adult. I have only seen first year birds before. This sparrow had a crisp whitish breast, unlike the buff wash on young birds. It did have tan flanks, a well marked face, a whitish crown stripe, and it was shaped like a Chipping Sparrow.
