This one also in transition to winter plumage.

Same individual as above. The flight feathers have not yet changed.

An individual thought to be female.

This one might be a male.

The individual with the most advanced moult.

Two birds at the far end of the rice paddy. So distant… ^^;

Wood Sandpiper, adult. Almost fully in breeding plumage but well worn and ragged.

Long-toed Stint, late breeding plumage.
