This is an Andean species ranging from southern Peru, through much of Bolivia (Departments of Santa Cruz, Tarija, Cochabamba, Chuquisaca, La Paz, Oruro and Potosi) and northwestern Argentina. It is present at elevations of 1,600-4,200m asl.
Habitat and Ecology
It is a terrestrial species of open montane puna grassland and semi deciduous forest habitats (De la Riva et al. 2000, Köhler 2000). Pairs build foam nests that float in small permanent and temporary pools. This species is present in agricultural land.
It is a common species throughout its range.
There are no major threats to this species in its range.
The species is present in several protected areas in Bolivia and two (Los Andes Provincial Reserve and Laguna Pozuelos National Park) in Argentina, but not found in Peruvian protected areas. There are no conservation measures needed for the species in Bolivia and Peru.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
Populations in highland areas have different calls and morphology when compared to the lowland populations. Nonetheless, a molecular study by McLister et al. (1991) did not find any difference between highland and lowland populations.
