I took great joy in watching these tiny Sanderlings along the water's edge on Plum Island, Massachusetts. When the water would recede, they would all scurry onto the newly-soaked sand, scrounging for a bite to eat.
When the next wave rolled in, they would turn, almost as a group, and scamper away from the curl of the water.
I managed to also catch them mostly in profile. They were a joy to watch!
