Thank you for your expert help. I have changed the ID on my checklist to reflect the truth.

   That is a Swamp Sparrow, the really rusty wings, bold triangular post ocular, and lack of crisp streaking below seal the ID. The two species are very similar as juveniles, but that only lasts for a very short time after fledging. At this time of year they are readily separable. Nice find!

In this checklist     I included two photos of a sparrow I have called Lincoln's sparrow. It could be mistaken for a swamp sparrow given that Sibley says the two as immatures are nearly indistinguishable from one another. The other option I considered and rejected was white-throated sparrow. I'm seeking opinions. Offline responses are welcome.
