Population justification: Estades (in litt. 2007) estimated the population to number 650 individuals in Azapa, and 550 in Vitor. This totals 1,200 individuals, roughly equivalent to 800 mature individuals. Previously, Estades et al. (2007) had calculated a Chilean population of 1,539 individuals in September 2003.
Trend justification: A slow and on-going population decline is suspected owing to habitat loss and degradation.
