Shorebirds at River Bay

I stopped at River Bay, St. Lucy on Friday.  Lots of shorebirds were present. Here are just a few example of the species I saw:

lots of Semipalmated Sandpiper (Calidris pusilla) like this on on its own island

I was surprised to find this American Golden - Plover (Pluvialis dominica) there

a few nice looking White-rumped Sandpiper (Calidris fuscicollis) like this one

only about three Lesser Yellowlegs (Tringa flavipes) but this one was photogenic 

I tried hard to turn these Semipalmated Plover (Charadrius semipalmatus) in to the much rarer  Ringed Plover (Charadrius hiaticula) but alas to no avail
