This sandpiper is larger than the Least, Semipalmated and Western. Its wing tips extend beyond the end of its tail, giving it a "pointed" look. The Baird's back is scaly with whitish edges, dark back feathers; all-white belly. Fairly distinct chest markings. The bird was named in honor of Spencer Fullerton Baird, for many years the Secretary of the Smithsonian.
Juveniles have buff faces and breasts and a more scaly pattern on their backs than the adults.
As do other sandpipers, the Baird's breeds on tundra in northern Alaska and Canada.
Calls or song.
This sandpiper emits a soft, "krrrrt" and also a loud trill.
Population and distribution.
Baird's Sandpiper migrates to South America along the Pacific Coast and through the Great Plains in fall, and returns through the Great Plains in spring. Small numbers may be found on the East Coast in fall, but can be overlooked because of their similarity to others of the species.
The famle Baird's lays 4 tawny eggs, spotted with brown. She finds dry tundra and makes a depression on the ground among rocks.
