Waders in Costa Rica, October (1 Viewer)

Hi forum,

I went to Ostional Beach (Pacific side) in Costa Rica in mid October. Apart from the hundreds of vultures and caracaras feeding on turtle eggs there were a few waders - something which is not my strongest side.
There were many Sanderlings and Ruddy Turnstones and then some others.
My guess is that he plovers are semipalmated plovers (Charadrius semipalmatus) - is that so? Or could there be a Wilson's or something else in between? And then there are the ones with brown/grey stripes on the chest - I guess they are a type of sandpiper?

Picture 1-5 shows birds from a group near the waters edge, picture 6-7 shows some birds who were a little further up the beach.

Any comments on ID would be greatly appreciated?

Thanks, Peter

All plovers look like Semipalmated to me. In #6, the sandpiper in the middle looks quite like White-rumped. On the others, though, I'm back and forth between White-rumped, Baird's, and Pectoral Sandpiper.

I am assuming you already distinguished the Turnstones and Sanderlings in #s 2-5.
 
I'm seeing at least Baird's (photo 1) and pectoral (e.g. photo 4, bird above the turnstone and sanderling with the rufous cap and neat breast band). Also possible white - rumped (middle bird 6). Might have a more forensic go at them later
