This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and therefore does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Geographic Range [top]

Range Description:This taxon occurs as four subspecies: andinus is found in north-west Argentina, conlara is found in San Luis and Córdoba provinces, western-central Argentina, patagonus is found from central to south-east Argentina, ranging occasionally into Uruguay in winter, and bloxami occurs in central Chile.
Countries occurrence:
Argentina; Chile; Uruguay
Additional data:
Continuing decline in area of occupancy (AOO):Unknown
Extreme fluctuations in area of occupancy (AOO):NoEstimated extent of occurrence (EOO) - km2:1590000
Continuing decline in extent of occurrence (EOO):UnknownExtreme fluctuations in extent of occurrence (EOO):No
Continuing decline in number of locations:Unknown
Extreme fluctuations in the number of locations:No

Population [top]

Population:The species is still common in many parts of its range in Argentina with only small range contractions reported in Córdoba (R. M. Fraga in litt. 2003). The population size of the four subspecies was estimated as follows by Masello et al. (2011): C. p. patagonus 43,330 nests, C. p. conlara 1,700 individuals, C. p. andinus 2,000 nests, C. p. bloxhami 5,000-6,000 individuals. Based on these figures, the total global population may number c.95,000 mature individuals.

Trend Justification:  The population is suspected to be in decline owing to ongoing habitat destruction and unsustainable levels of exploitation.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:95000Continuing 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:The species inhabits arid lowland and montane grassy shrubland, open dry woodlannd savanna, open Chaco plains along watercourses, and thorny scrub or columnar cacti, often with a sandy substrate, at elevations up to 2000 m (del Hoyo et al. 1997). The species may only breed successfully in fairly large, dense colonies (J. Burton in litt. 2002).
Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):6
Movement patterns:Full Migrant

Threats [top]

Major Threat(s): The species has been heavily traded: since 1981 when it was listed on CITES Appendix II, 122,914 wild-caught individuals have been recorded in international trade (UNEP-WCMC CITES Trade Database, January 2005).
