Often described as looking like a yellowlegs and feeding like a dowitcher, the Stilt Sandpiper is a medium-sized, long-legged wader. Its breeding plumage is distinctive, but rarely seen in Washington. It is heavily barred brown-and-white above and below, with a white eye-line that separates a rufous cap and cheek. In non-breeding plumage, the Stilt Sandpiper is pale gray, with a light, unstreaked belly and white eye-line. Juveniles are light brownish-gray with lightly streaked breasts and scaled backs. In flight, they show gray and white underwings, solid gray upperwings, white rumps, and gray tails.
