The Beryl-spangled Tanager (Tangara nigroviridis) is found at high elevations in Venezuela, Colombia, Ecuador, Peru, and Bolivia. Much of the head and underparts are black, heavily spotted, the spots appearing bluish or greenish. This feature gives them their brightly-colored, "spangled" appearance. Other plumage characteristics include a black mask, bluish-green rump, and bluish wings. There are four currently recognized subspecies of Tangara nigroviridis. These tanagers are highly social, and tend to travel in pairs or in flocks of 3-25. In addition, they are often encountered in mixed-species flocks. Like other Tangara, they are omnivorous, feeding on both fruit and arthropods. Although common in some parts of their range, there is little information on the behavior, predators, demography, and other aspects of the biology of the Beryl-spangled Tanager.
