Feeding Behavior

On mudflats and in marshes, forages mostly by probing in water or mud with long bill. Often wades and probes so deeply that head is underwater. Finds most food by touch; may feed by day or night. On prairies, also picks up insects from surface of ground or plants.

Eggs

4, rarely 3-5. Greenish to olive-buff, lightly spotted with brown. Incubation is probably by both parents, 21-23 days. Incubating bird may sit motionless even when approached closely. Young: Downy young leave nest soon after hatching. Both parents tend young, but young find all their own food. Age of young at first flight roughly 3 weeks.

Diet

Includes insects, mollusks, crustaceans. In summer on prairies, feeds mostly on insects, including many grasshoppers; also roots and seeds of various aquatic plants, such as sedges and pondweeds. On coast, feeds on mollusks, marine worms, crustaceans, other invertebrates.

Nesting

May nest in loose colonies. Male displays over breeding territory by flying over area, calling loudly. On ground, members of pair may go through ritualized nest-scrape making display. Nest site is on ground, usually in short grass on dry spot fairly close to water (sometimes far from water). Nest is slight depression, lined with dry grass. Occasionally has slight canopy of grass arranged above nest.
