Overview

The dot-winged crake is a near threatened species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Argentina, Brazil, Chile, and Uruguay.

The Dot-winged Crake faces severe population declines primarily due to widespread habitat loss and degradation of wetland ecosystems throughout its range in South America. Agricultural expansion, urban development, and drainage of marshlands for cattle ranching have significantly reduced available breeding and foraging areas.
