I thought the sparrow was a white throated, but it does look like Savannah.
As far as the shorebirds ...
I thought the first was a greater yellowlegs and then I tried to convince myself that it was a Solitary Sandpiper even though the legs look yellow and not green. The second one I thought was a Sanderling while I was watching it running all over the place, but later when I looked at the photos, I tried to make it into a Western or Least Sandpiper. Sigh. First impressions seem to be best.
Thanks much Chilly and Resin. I appreciate your help.
