Population justification: A total of 8,988 individuals were counted in Argentina in 1995, 2,800 in Bolivia in 1982 and 620 are estimated in Chile. The total is probabaly in the range of 10,000-19,999 individuals, and probably fluctuates greatly. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and unsustainable levels of hunting.
