Behavior


Movement

The red-and-white crake appears to be a year-round resident throughout its range.


Feeding

The red-and-white crake usually forages by itself, walking on the ground or climbing among vegetation. Its diet is mostly small invertebrates such as insects and worms, and also includes seeds.


Breeding

The red-and-white crake's breeding season in Argentina appears to span from October to February but is not known elsewhere. Both sexes build the nest, which is a ball of grass, herbs, and reeds attached to marsh vegetation up to about above the ground. It has a side entrance. The typical clutch size is three eggs. In captivity the incubation period is about 24 days and young are independent in about four weeks.


Vocalization

The red-and-white crake's song is "a prolonged throaty chatter; also described as a resonant trill", sometimes given in duet. An alarm call is "a low ''cui'' whistle" and a call believed to be aggressive is a "harsh ''chrrrrrr...''".


Status

The

has assessed the red-and-white crake as being of Least Concern. It has a fairly large range, but its population size and trend are not known. No immediate threats have been identified. However, "habitat destruction by urban growth, land filling and livestock grazing" have a direct effect.
