Population justification: The population is preliminarily suspected to number 2,500-9,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the range is likely to be occupied. This value is equivalent to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Based on observational records (eBird 2020), it is suspected that the species forms two subpopulations. Under the assumption that the total population size is closer to the lower end of the estimate, the largest subpopulation may number below 1,000 mature individuals.

Trend justification: The population trend has not been assessed directly, but habitat within the range is slowly lost and degraded though burning (Valqui and Fjeldså 1999). It is precautionarily suspected that this is causing the population to decline; however any declines are likely very slow.
