Justification of Red List Category
This species has a moderately small, declining population within which all its subpopulations are believed to be small. It is consequently classified as Near Threatened.
The population is preliminarily estimated to number 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. The estimate requries confirmation.
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Cypseloides rothschildi occurs in north-west Argentina (Jujuy, Salta, Tucumán, Catamarca, Santiago del Estero, Formosa, La Rioja and Córdoba), south-east Bolivia (Santa Cruz, Chuquisaca and Tarija), with one record from Cuzco in south Peru (Armonía 1995, Chantler and Driessens 1995, J. C. Chebez in litt. 1999). It has been recorded in forest and open country at 800-2,000 m, but very little is known of its behaviour or status.
It is probably most common in ravines and gorges of wet montane areas with numerous waterfalls for breeding sites (Chantler and Driessens 1995).
Large tracts of the yungas forests in the core of its range have been cleared, particularly in Argentina, owing to logging of valuable timber, conversion for agriculture, plantations of Pinus spp., road-building and human colonisation (Vervoorst 1979, WWF/IUCN 1997).
