Feeding Behavior
Forages by walking in shallow water or on mud, especially on falling tide or at low tide, picking up items from the ground or vegetation, sometimes probing in mud or water.
Eggs
Usually 7-11, sometimes 5-12 or more. Pale yellow to olive-buff, blotched with brown and gray. Incubation is by both sexes, 23-29 days.
Young
Downy young may leave nest soon after hatching. Both parents probably feed young. Parents may brood young in a separate nest from the one in which the eggs hatched. Young can fly in about 9-10 weeks.
Diet
Includes crustaceans, insects, fish. Diet varies with locality, and includes a wide variety of small prey. Crustaceans often favored, especially crabs, also crayfish and others. Also eats many aquatic insects, small fish, mollusks, worms, frogs. Eats seeds at times.
Nesting
Courtship displays are not well known. Male may feed female. Nest site is in clump of grass or other vegetation in marsh, near the upper reaches of high tide, or on bank near water. Nest (built mostly by male) is well-built cup of grasses and sedges, lined with finer material, often with vegetation woven into a canopy over nest. Often a ramp of plant material leads from ground up to nest.
