Population justification: No empirical data is available, however, despite it apparent low population density and ongoing habitat degradation and fragmentation within the species's range, an extensive area of potentially suitable habitat remains that suggests the previous population estimate of 50-250 individuals needed revision. It is instead estimated to number 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: Threats to the cerrado are many and varied; particularly so within the species's range. For this reason a very rapid rate of decline is precautionarily suspected, but collection of empirical evidence to clarify this remains a priority,
