Distribution and Habitat
This bird breeds in marshes in eastern North America. Birds along the southeastern coasts of the United States are permanent residents. Other birds migrate to the southern United States and Mexico; in Canada, they are found in southern Ontario. An adult King Rail will molt completely after nesting and it becomes flightless for almost a month.
The king rail lays a clutch of 6 to 14 pale buff eggs with brown spotting. They usually measure 41 by 30 millimetres (1.6 by 1.2 in). Both parents incubate the eggs for 21 to 23 days. When the eggs hatch, the young are covered in down and are able to leave the nest. They are not, although, able to feed themselves, and thus must rely on their parents for food for up to six weeks after they hatch.
The chicks are fed small arthropod prey by their parents. The prey is transferred from one parent's beak to that of the chick.
In the males, they will give food to whoever it mates with during engagement.
