Population justification: The species is described as rare and local. Sightings usually involve small numbers of individuals, and come from a very small number of sites. The population size is therefore expected to be low and tentatively placed in the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 mature individuals, rounded here to 3,500-15,000 mature individuals; however, this may be an underestimate. In recent years, the species is more regularly observed in Chile, which may be attributable to an increase in survey effort, rather than to an increase in population size (F. Schmitt in litt. 2020).
Trend justification: The population trend has not been estimated directly. Even though the impact of potential threats on the population size is virtually unknown, it is precautionarily suspected that the species is undergoing a slow decline, not exceeding 10% over ten years.
