Cinnamon Tanager occurs mainly in Brazil south of the Amazon and uses semi-open grassy country with scattered shrubs and low trees. A specimen study describes a cinnamon-colored throat and breast and a whitish belly. It found substantial individual and geographic variation in plumage, so one color pattern does not represent every bird.
The throat and breast are reddish yellow or cinnamon, while the belly is whitish. The specimen study reports substantial individual and geographic variation in plumage.
It inhabits semi-open grassy country with scattered bushes and low trees; the paper also describes it as especially common in high mountain meadows above treeline.
