Population justification: The species is described as locally common in French Guiana and Venezuela (Hilty 2003, GEPOG per O. Claessens and V. Pelletier in litt. 2020), but as rare to uncommon in the remainder of its range in Guyana and Suriname (Stotz et al. 1996, O. Ottema in litt. 2020), though it may be overlooked (O. Ottema in litt. 2020). The population in French Guiana is estimated at 2,000-20,000 individuals (GEPOG per O. Claessens and V. Pelletier in litt. 2020), which may roughly equate to 1,300-13,000 mature individuals.

Assuming a similar density in Venezuela, the population there may number 500-5,000 mature individuals. Assuming further that the species reaches half the density in Guyana, Suriname and Brazil, the population in these range states may amount to 4,300-43,000 mature individuals. The global population is therefore tentatively placed in the band 6,000-61,000 mature individuals, though this requires confirmation.

Although there is little information about the species's subpopulation structure, the species is monotypic and there is no evidence to suggest that there are distinct subpopulations, so it is assumed that there is only one subpopulation.

Trend justification: While trapping for the cagebird trade has been a threat in the past, this now has only minor impacts on the population size, if at all (Dickey 2020, O. Ottema in litt. 2020). Habitat loss is low within the range, and large tracts of forests are still in pristine conditions (Tracewski et al. 2016, O. Ottema in litt. 2020). However, inland forests are increasingly logged and degraded through gold mining (O. Ottema in litt. 2020).  Over 19 years from 2001-2019, approximately 1% of tree cover with at least 30% canopy cover was lost within the species's mapped range (Global Forest Watch 2020). Scaled to three generations (44.22 years), this would equate to a loss of 2%. Over 2016-2019, approximately 0.4% of tree cover was lost within the species's range (Global Forest Watch 2020). If this rate were to continue for three generations (44.22 years), approximately 4% of tree cover within the species's range could be lost. The species is therefore tentatively suspected to be undergoing a slow decline at a rate of <10% over three generations.
