Population justification: There is no direct data on population densities, but the species appears to be rare and very sparsely distributed. In Argentina, searches in forest remnants across central and northern Misiones over five years only detected the species at six sites (Bodrati et al. 2009).

Based on the lower density estimates for the closely-related species P. chloris (0.5-1.6 individuals/km²; Thiollay 1986, 1992), the approximate area of tree cover with at least 50% canopy cover within the species's range in 2010 (84,000 km²; Global Forest Watch 2020), and assuming 10-25% of the tree cover within the range is occupied, the population size is tentatively suspected to fall between 4,200 and 33,600 individuals, which is assumed to roughly equate to 2,800 - 22,400 mature individuals.

The subpopulation structure is poorly known, but assuming the population size falls towards the lower end of the range, and that there are at least several subpopulations, the largest subpopulation is suspected to have fewer than 1,000 mature individuals.

Trend justification: The population is thought to be in decline, but the trend has not been estimated directly. Remote-sensed data indicates that approximately 6% of tree cover was lost within the species's range over ten years from 2009-2019 (Global Forest Watch 2020). Although the species has specialised habitat requirements and occurs at higher elevations, it is dependent on forest and is therefore inferred to be declining.

Based on the amount of tree cover loss, over ten years from 2010 to 2020, the species's population size is tentatively suspected to have undergone a reduction by 1-6%. Assuming a similar rate of forest loss continues into the near future, the species is suspected to undergo a reduction of 1-9% over the next ten years.
