The worldwide taxonomic systems agree that the species is
Description
The dot-winged crake is 14 to 15 cm (5.5 to 5.9 in) long. The sexes are alike. Their upperparts are dark olive brown with blackish streaks and some white markings on the flight feathers. Their face and breast are dark gray and their vent area and undertail coverts are barred black and white.[10]
Distribution and habitat
The dot-winged crake's distribution is unsettled. The IOC and Clements place it in southern Uruguay and northern Argentina.[2][8] The Cornell Lab of Ornithology's Birds of the World adds Brazil's southernmost state, Rio Grande do Sul, and the SACC adds Chile to those three countries.[10][4] Cornell's eBird has records in all four countries.[11]
The dot-winged crake inhabits freshwater and brackish waters and some drier landscapes as well. It is found in freshwater and tidal marshes, swamps, wet meadows, grasslands, and riparian scrub.[10]
Behavior
Movement
No movements are known for the dot-winged crake.[10]
Feeding
The dot-winged crake feeds on insects, seeds, and marsh vegetation. Its foraging technique has not been documented.[10]
Breeding
A dot-winged crake nest was discovered near Buenos Aires but no details of it or any other aspects of the species' breeding biology are known.[10]
Vocalization
The dot-winged crake's song is " a high note followed by a lower-pitched rattle 'kee-krrrrr'" that is repeated several times. Its calls include "a mellow soft 'pwup' and a scolding rattle."[10]
