Feeding Behavior

Mostly forages in shallow water, in or close to dense marsh cover. Large items (such as big crayfish or crabs) may be carried to solid ground and dismembered before being eaten.

Eggs

Usually 10-12, sometimes 6-14. Pale buff, lightly spotted with brown. Incubation is by both sexes, 21-23 days. Young: Downy young leave nest a few hours after hatching. Both parents feed young; after about 3 weeks, young start to pick up much of their own food. While young are small, adults may brood them at simple nest platforms near where they hatched. Young are able to make short flights at about 9-10 weeks. May have two broods per year in south.

Diet

Mostly insects and crustaceans. Diet includes many aquatic insects, especially beetles. Eats many crayfish and crabs, and sometimes many small fish. Also eats snails, clams, grasshoppers, frogs, spiders, and seeds of aquatic plants.

Nesting

In courtship, male walks about with tail raised, showing off white under tail coverts. Male may feed female. Nest site is in a clump of grass or sedges, usually about a foot above water or land. Nest (apparently built mostly by male) is a solid platform of grass, sedges, other marsh plants, with a canopy woven over the top and a ramp leading down from the entrance. Additional simpler nest platforms may be built nearby.
