To all:
sorry for the delay in responding to this post, but my house is only 7 feet above sea level near Cape May NJ, and Hurricane Irene had my attention for about 5 days while I moved furniture and tried to minimize the expected tidal surge damage to my home. The good news is that we had no tidal surge, and I got to see two White-tailed Tropicbirds and one Black-capped Petrel from Cape May Point during the Hurricane, besides numerous Bridled and a handful of Sooty Terns.
Male Semipalmated Sandpipers show almost no primary projected past the tail, and very little projection past the longest tertial. However, some larger females show noticeable primary projection past the tail, and also past the longest tertials. These females have a much more attenuated appearance than small males, which look very compact. This Semi is in between the extremes of primary projection between large females and small males, and I would not attempt to sex this bird. Kevin Karlson

Dan, All:
IMO your peep plumage looks spot on for a HY SESA.
The only confusion for me is the uncertainty of wing/tail length.
IE: are the wings really extended past the tail?
Here a like bird in strong light, note the lack of primary extension.

Last month while birding at the south end of the Salton Sea, I came across a
juvenile, western-type sandpiper that I suspected was a semipalmated
sandpiper. I snapped a few photos and went home. Upon reviewing the photos,
I noticed that I had captured one showing quite well that the bird had no
palmations at all. I sent the photo around to a few friends and got mixed
reviews. Some discussion has been given to the possibility of red-necked
stint. Many traits of this bird point to red-necked stint, but a few do not.
I suspect this will come down to whether or not semis and westerns can really
have zero webbing. Here are 4 photos of the bird. Thanks for taking a look.
