These are two of four Least Sandpipers I found by the creek, early south-bound migrants expected in July. The yellow flowers behind them are Water-Primrose (Ludwigia octovalvis).
FOS, at least 5 counted. Unfortunately this one was missing a leg.

Worn breeding plumage.
The calidrids or typical waders are a group of Arctic-breeding, strongly migratory wading birds. These birds form huge mixed flocks on coasts and estuaries in winter. They are the typical "sandpipers", small to medium-sized, long-winged and relatively short-billed.
