distribution and habitat

The species inhabits the caatinga , which is characterized by dense bushes , mainly in the vicinity of small areas dominated by trees.

Danger

Information on the size of the world population is not available. The species does not seem to be very abundant, in suitable habitats also quite abundant locally. The population is probably declining due to the destruction and overexploitation of the caatinga, the species is therefore classified by the IUCN as a type of the warning list ("near threatened").
