Resin, the wing tips of Baird's extend beyond tip of tail, according to my references. I did consider Semi-p. from the beginning. After reexamining the photos, including many not posted, I still believe the first three pictures are Baird's. But, now think the fourth picture could be a Semi-p. I can't really see the tail on any of the shots of the bird on the beach.

boojum, here is another shot of a baby peep. It was one of three observed in the same area as the bird in the 4th. picture, but not with the adult. The were old enough to be feeding on their own.
