Three Stilt Sandpipers feeding as a group. All the other Stilt Sandpipers I saw were feeding with Yellowlegs and Dowitchers with no other Stilt Sandpipers around. Note that the color of the legs of the bird on the right is obscured by shadow.
Stilt Sandpipers are long distance migrants. They breed in the open arctic tundra of North America and migrate, primarily, to inland central South America. Although some overwinter in the southern U.S., I have seen them only during fall and spring migration.
