This species has a moderately small population which is declining owing to habitat loss. It is consequently classified as Near Threatened.
|Previously published Red List assessments:||
|Range Description:||This species is restricted to the xeric woodland and savannas of the central and southern Chaco and the woodlands of the foothill Chaco in south Bolivia (Tarija), west Paraguay (Nueva Asunción, Boquerón, Presidente Hayes) and north-central Argentina (Formosa, Chaco, Santiago del Estero, Córdoba, San Luis and Corrientes), and transitional subtropical forest up to 1,500 m in the low Andean foothills of south-central Bolivia (Santa Cruz) and north-west Argentina (Salta, Tucumán) (Canevari et al. 1991, Madroño and Pearman 1992, Chebez 1995, Winkler et al. 1995). It appears to have always been rare, or perhaps under-recorded, but has declined over much of its former range in Argentina. It survives mainly in two isolated population centres in Córdoba and adjacent San Luis, and the central Paraguayan Chaco (Madroño and Pearman 1992, García Fernández et al. 1997, H. Casañas in litt. 1998).

|Population:||The population is preliminarily estimated to number at least 10,000 individuals, roughly equating to 6,700 mature individuals. This requires confirmation.
Trend Justification: The population is suspected to be in decline owing to ongoing habitat destruction.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Its habitat preferences are not clear, but it has been found breeding in mature horcoquebracho Schinopsis hankeana and Lithraea ternifolia woodland (Heredia et al. 1999), and has been found in timber plantations.
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||5.8|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Habitat loss is principally the result of logging of quebracho (Aspidosperma spp., Schinopsis quebrachocolorado) and algarrobo (Prosopis spp.) for charcoal, tannins and railway sleepers, land clearance for agriculture and cattle-ranching, and plantations of non-native tree genera (Madroño and Pearman 1992, Winkler et al. 1995, H. Casañas in litt. 1998).|
Conservation Actions Underway
In Argentina it has been recorded in Formosa Natural Reserve, Río Pilcomayo National Park (Formosa), Chaco National Park (Chaco), and Chancaní and Cerro Colorado Provincial Reserves (Córdoba). Conservation Actions Proposed
Effectively protect and manage protected areas where the species occurs. Study its ecology and its ability to persist in small isolated populations in degraded and fragmented habitats.
