Three subspecies of Buff-breasted Mountain-Tanager range through the Andes from western Venezuela to southern Peru, at elevations between 2000 and 3500 m. This tanager usually is solitary or in pairs, which typically are associated with mixed species flocks. The species always inhabits low dense vegetation, including Polylepis woodland. Until recently, Buff-breasted Mountain-Tanager was considered the sole representative of the genus Dubusia, until taxonomy based on molecular systematics moved Chestnut-bellied Mountain-Tanager (Dubusia castaneoventris) to this genus from its previous genus Delothraupis. Both members of this genus inhabit high elevations in the Andes of Peru and have very similar songs. They differ in their choice of feeding strata, with Chestnut-bellied Mountain-Tanager selecting the crowns of trees. The common name in Spanish is Tangara Pechifulva (Hilty 2011, de Juana et al. 2012). The etymology of the genus name Dubusia is an eponym honoring Bernard Aime Leonard Vicomte Dubus de Ghisignies, a patron of science, and the specific epithet taeniata is Latin for head-band (Jobling 2010).
