Opal-rumped Tanagers are a colorful members of the genus Tangara that are widely distributed, although uncommon), throughout the forests of Amazonia and the Atlantic forests of eastern Brazil. There are three similar subspecies in Amazonia, and a fourth (T. v. cyanomelaena) that is geographically isolated in the Atlantic forests and which shows marked differentation in morphology and plumage. Thus, it may represent a separate species (Pinto de Assis 2008). Opal-rumped Tanagers often forage in the canopy as pairs, frequently as members of mixed species flocks, and feeding primarily on fruit, berries, and insects. Many aspects of the life history pf this tanager are not well known.
