CLOSED: Shore birds ID?

I'm hoping someone will recognize these. I have two diff. birds that I just couldn't pin down as to there ID. I have two pics of the first one. Is it a black bellied plover? Here's the first pic.

Here's the 2nd pic... (these were taken in Oct. if that helps)

This is the other unidentified one. Some kind of sandpiper? It's the taller grayer one, not the little short brownish fellows who I believe are Ruddy Turnstones.
TIA!

Pics 1 & 2 - Black-bellied Plover (a.k.a. Grey Plover), winter plumage

Pic 3 - Red Knot, winter plumage, together with Ruddy Turnstone

Resin: I just knew you would answer! :) I can't believe I got the Plover right!
I'd probably never have arrived at Red Knot, though, without your help.
Thanks so much!

nice pics Deb. Winter plumage in shore birds making ID very difficult at time
