Brassy-breasted Tanager is a common species endemic to the country of Brazil in South America (Parker et al. 1996, Clements 2010). Brassy-breasted Tanagers are restricted to southeastern Brazil, ranging north to Espírito Santo, extending west into Minas Gerais, and south through Paraná to Santa Catarina (Sick 1993, Isler and Isler 1987, Ridgely and Tudor 2009). The Brassy-breasted Tanager does not occur on the coastal plain, but instead is usually is found between 500 m and 2200 m (Ridgely and Tudor 1989, Parker et al. 1996), van Perlo 2009, but mostly resides within an elevational range of 800-1800 m (Isler and Isler 1987, Ridgely and Tudor 2009). BirdLife International (2011) estimates the geographic range of the Brassy-breasted Tanager to be approximately 220,000 km2. Although seasonal migration patterns of Brassy-breasted Tanagers are poorly understood, this species is presumed to be a permanent resident in southeastern Brazil, but possibly a partial migrant to Espírito Santo (Parker et al. 1996, Isler and Isler 1987). The Brassy-breasted Tanager is generally found at higher elevations than the closely related Gilt-edged Tanager (Tangara cyanoventris), for example at Itatiaia National Park (Ridgely and Tudor 1989).
