Population justification: The population size has not been quantified. The species is described as locally common in protected areas, but as generally rare throughout its range (ICMBio 2018, del Hoyo and Kirwan 2020).
Trend justification: Once considered common, the species is now described as rare and has become extinct in coastal Alagoas and Paraíba, with high hunting pressure and habitat loss being the main drivers of the decline (ICMBio 2018, del Hoyo and Kirwan 2020). Tree cover loss within the range amounts to up to 19% over three generations (22.3 years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The impact of hunting has not been quantified, but it is described as severe across the entire range (ICMBio 2018). It is therefore suspected that the combined impacts of tree cover loss, habitat degradation and hunting are causing population declines of 30-49% over three generations.
