Population justification: The population may exceed 10,000 mature individuals, thus it is suspected to number 10,000-19,999 mature individuals, roughly equivalent to 15,000-30,000 individuals in total; however, more research is required.

Trend justification: This species's population is suspected to be in moderately rapid decline, owing to the loss and degradation of caatinga scrublands, although data are lacking on the magnitude of these effects.
