Looks like pectoral 

I was birding Mann Lake near Lewiston yesterday and came across these shore birds. I am not strong in my shorebirds identification. The two were quite large compared to the surrounding shorebirds. The smokey conditions did not help. I returned this morning but there were only Baird’s Sandpipers and 2 Greater Yellowlegs. If anyone can help me with the identification of them it would be greatly appreciated.
