About Trichothraupis melanops (Vieillot, 1818)
The black-goggled tanager, with the scientific name Trichothraupis melanops (Vieillot, 1818), is a bird species belonging to the family Thraupidae, and it is the only member of the genus Trichothraupis. This species occurs at low elevations in forests and woodlands across a large portion of eastern and southern Brazil, eastern Paraguay, and far northeastern Argentina. It also has a geographically separated disjunct population along the eastern slope of the Andes, ranging through Peru, Bolivia, and far northwestern Argentina. While the species as a whole is generally common, widespread, and classified as Least Concern by BirdLife International and the IUCN, the Andean population is relatively localized and uncommon. The underparts of the black-goggled tanager are tawny, while the back and head are dull brownish-olive. Its tail and wings are distinctly contrastingly black; the wings have a white speculum that is hard to see when the bird is perched, but stands out clearly during flight. Males have a yellow patch on the crown and a large black patch surrounding the eyes, the black 'goggles' that give the species its common name.
