Black-bellied Plover  10
Semipalmated Plover  365
Common Ringed/Semipalmated Plover  1    Pans, feeding with flock of SEPLs. Thick breast band, especially at sides of breast, and thick across front of breast. Hint of eye-ring, but for the most part dark / lacking. Black on face meets bill at the gape, and not just above gape as in SEPL (the most reliable field-mark I’ve used in AK for separating the two). I’m hesitant to call this CRPL as: bill is not particularly long, and neither is the supercilium very bold. I didn’t notice any obvious difference in size between this bird and others. Silent and no observation of feet. Poor digiscoped pics.
Piping Plover  6
Killdeer  1
Sanderling  8
Baird’s Sandpiper  1
Least Sandpiper  13
White-rumped Sandpiper  17
Semipalmated Sandpiper  275
Western Sandpiper  4    At pans. At least 4, perhaps 5. All that I saw had rufous on scapulars but not on head. Larger size and longer bill than nearby Semipalmated Sandpipers.

Long-billed Dowitcher  2
Spotted Sandpiper  3
Greater Yellowlegs  30
