Population justification: The species is locally common (Roda et al. 2011). No systematic surveys have taken place, but based on the observations of numerous ornithologists throughout the species' range, the population size is estimated to be less than 10,000 mature individuals (Silveira et al. 2003, 2023). The population size is therefore placed in the band 2,500 - 9,999 mature individuals.

Trend justification:

The population trend has not been investigated, but declines are inferred due to the species' disappearance from previously occupied sites in Pernambuco and possibly Rio Grande do Norte (Silveira et al. 2003, 2023). The main drivers of the decline are habitat loss and trapping pressure.
Tree cover is lost at a rate of 3-5% over ten years within the range (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Although the species tolerates altered habitats, it is also threatened by trapping for the illegal cagebird trade. The impact of trapping on the population size has not been quantified, but both trapping intensity and subsequent mortality appear to be high (Silveira et al. 2003). Consequently, the rate of population decline may be steeper than the rate of tree cover loss alone. It is here tentatively placed in the band 10-19% over ten years, though an accurate quantification is urgently required.
