Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Contributor(s): Chebez, J.
Facilitator/Compiler(s): Babarskas, M., Benstead, P., Capper, D., Sharpe, C.J., Symes, A.
Justification:
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.

Geographic Range [top]

Range Description: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.

Population [top]

Population: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.

Trend Justification:  The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Current Population Trend:Stable
Additional data:
Number of mature individuals:6000-15000Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It is probably most common in ravines and gorges of wet montane areas with numerous waterfalls for breeding sites (Chantler and Driessens 1995).

Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):8
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): 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).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None is known.

Conservation Actions Proposed
Study its ecological and habitat requirements. Study threats. Clarify its distribution in Bolivia and its presence in Peru. Clarify whether it makes seasonal movements. Protect areas of suitable habitat and safeguard against clearance and encroachment.
