Baird’s Sandpipers are brown shorebirds with black legs and very long wings. Their medium-length bills are fine-tipped and straight. Adults in breeding plumage are light brown, and have black spots on their wings. Non-breeding adults are gray-brown, and lack spots. The juvenile, the most common form found in Washington, is brown with white-edged feathers that give it a scaly appearance. In flight, it shows white wing-stripes and a dark line down the middle of its tail, with white on either sides of the rump.
