The Green-headed Tanager occurs from southeastern Brazil into adjacent northeastern Argentina and southeastern Paraguay. More specifically, it occurs in southeastern Brazil (southern Bahia south to northern Rio Grande do Sul), northeastern Argentina (Missiones) and eastern Paraguay (including Canendiyu, Alto Paraná, and Itapú) (Ridgley and Tudor 1989). This species occurs from the lowlands up to 1300 m (Parker et al. 1996). Isler and Isler(1987) indicate it occurs to about 900 m and is more abundant at lower elevations. Likely a resident species, but Isler and Isler (1987) indicate it might move seasonally between forest and semiopen areas.
Distribution outside the Americas
Endemic to South America.
Occurs primarily in tropical lowland evergreen forest, but also occurs in montane evergreen forest and in second growth (Parker et al. 1996). Also observed at forest edges, plantations, parks, fruit trees in cultivated areas, shrubby clearings, and gardens (Isler and Isler 1987, Ridgely and Tudor 1989). However, does not occur in large expanses of deforested lands (Ridgely and Tudor 1989).
Numbers have declined due to deforestation of its habitat in southeastern Brazil (Ridgely and Tudor 1989), but the overall geographic distribution is not known to have changed significantly.
