Proportions are more important for separating two species; bill longer than the head and slightly upturned. Larger overall size than Lesser Yellowlegs with longer neck, blockier head, and bigger chest. Forages actively on mudflats and shallow water areas, taking long strides and reaching down to snatch invertebrates. See also: Lesser Yellowlegs.
