I don't agree with you on this one. You can see the rufous scapulars of this bird that has not yet been moulted. I have two more pictures of this same birdhttp://www.pbase.com/ahlman/image/152772025 that may show better.
Thanks for your comment

Roger, I think the bird on the left is a female semipalmated sandpiper Ben Haase
