The turquoise tanager (Tangara mexicana ) is a medium-sized passerine bird in the tanager family Thraupidae. It is a resident bird from Trinidad, much of Brazil (despite its scientific name, it is not found in Mexico), Colombia and Venezuela south to Bolivia. It is restricted to areas with humid forest, with its primary distribution being the Amazon, while a disjunct population occurs in the Atlantic Forest of eastern Brazil. The latter population is sometimes considered a separate species, the white-bellied tanager (Tangara brasiliensis ).
It occurs in forest, woodland and cultivation. The bulky cup nest is built in a tree or shrub, and the female incubates three brown-blotched grey-green eggs.
These are social birds usually found in groups. They eat a wide variety of fruit and also take insects, often gleaned from twigs.
