Mongolian Lesser Sand Plover (and other birds) in the South Bay

I went to the San Diego National Wildlife Refuge in the South Bay to check out reports of a lesser sand plover (also known as a Mongolian plover).  I found him, but didn't get great pictures of him because of the distance:

There were an awful lot of western sandpipers there along with dowitchers, stilts, godwits, willets, avocets, phalaropes, and semipalmated plovers.  I didn't expect to see this many shorebirds:

Look at these western sandpipers huddled up on the sand:

Some of these little guys let me get a close-up photo:

I didn't see the two rare sandpipers, but I heard they would be hard to spot even if I could access the area where they usually are.  I was more interested in the plover.

There were two adorable baby black-necked stilts, one was close to me, another was near where the plover liked to hang out:

Lots of semipalmated plovers.  This one seemed to be keeping an eye on everyone:

And, lots of savannah sparrows, but I think I only saw one Belding's savannah sparrow (not this one):

They like to glean from the vegetation:

There were killdeer, too.
