Population justification: The global population size or density have not been quantified, but this species is described as rare or uncommon and patchily distributed (Stotz et al. 1996, Diniz and Santos 2020).
Trend justification: Although precise data on the population trend are lacking, declines are feared to be occurring owing to habitat loss and trapping for the wild bird trade. The species has become locally extinct in parts of its range in Brazil (Diniz and Santos 2020).
Rates of decline are difficult to quantify due to the species' occurrence in a variety of forest and semi-open savanna, as well as in 'cerrado' and grassland habitat or even disturbed sites. Tree cover within the range has been lost at a rate of up to 16% over the past ten years (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). The impact of trapping has not been quantified, but a study in Piauí in northeastern Brazil reported this species to be a major target for trappers (Souto et al. 2017). Under the tentative assumption that the rate of tree cover loss (16% over ten years) may be a proxy for the overall rate of habitat loss, and that trapping contributes an additional 5-10% decline, the overall rate of population decline is here suspected at 21-26% over ten years.
