Habitat
Understorey of dry, seasonally deciduous forest in rain-shadow valleys. Also, low, bushy vegetation in adjacent cleared areas. From c.1,800 - 3,300 m.
R Cotacajes drainage in La Paz (sight records also from R Consata drainage) and Cochabamba, in central Bolivia.
Rarity Status
Currently this species is not classified as a rarity in this country OR information has not been updated.
Population
Estimated population is 1,000 - 2,499 (2010) and decreasing.
Status EN
Habitat destruction and degradation through cutting for firewood, selective logging and poor regeneration because of grazing by goats and burning, are the main threats.

Subspecies
No subspecies.
Genetic data indicate that this is sister-species to Stripe-crowned Spinetail (Cranioleuca pyrrhophia) and the two are considered by some to form a superspecies that also includes Crested Spinetail (Cranioleuca subcristata), Olive Spinetail (Cranioleuca obsoleta), Pallid Spinetail (Cranioleuca pallida), Creamy-crested Spinetail (Cranioleuca albicapilla), Line-cheeked Spinetail (Cranioleuca antisiensis) and Baron's Spinetail (Cranioleuca baroni), but genetic data suggest that at least the last two of those are not part of this lineage.
