Population justification: The global population size has not been quantified. It is generally described as rare and uncommon, being patchily distributed and occurring at low density (Stotz et al. 1996, Collar and Boesman 2020). It can however be locally common to fairly common, e.g. in large forest fragments in the Itajaí Valley (G. Kohler in litt. 2011, Collar and Boesman 2020). The population in its stronghold in Rio Grande do Sul is suspected to number 10,000 individuals (Bencke 1996), while the east slope of the Serra do Mar may hold significant numbers; however, the apparent rarity of the species suggests that these figures may be an overestimate (J. Gilardi in litt. 2010). Based on available evidence the population is tentatively placed in the band 10,000-19,999 mature individuals.

Trend justification: The species is assessed as being in decline caused by the loss, fragmentation and degradation of its habitat, trapping for the cage-bird trade and hunting for food (Collar and Boesman 2020). Tree cover within the range is lost at a rate of 5-6% over three generations (11.6 years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The impact of hunting and trapping on the population size has not been quantified. Overall however, the decline is not believed to be rapid because because the species occurs in montane areas where deforestation is typically less severe, it appears to tolerate secondary growth, plantations, orchards and urban woodlands, and anecdotal observations suggest it is locally stable, for example in Tres Picos State Park, Rio de Janeiro (A. Foster in litt. 2013, Collar and Boesman 2020). Based on the available evidence, it is tentatively suspected that the population decline does not exceed 20% over three generations.
