Until the early 1970s, Yellow-scarfed Tanager generally was considered to represent a subspecies of Golden-crowned Tanager (Iridosornis rufivertex). Compared to the latter species, Yellow-scarfed Tanager has the yellow on the head as a band across the nape and ear coverts, and the undertail coverts are blue, rather than tawny. This beautiful tanager is endemic to Peru, where it ranges widely over the east slope of the Andes, principally at elevations between 2600 and 3100 m, and is found in montane and elfin forests. It moves quickly through the lower stories usually in the company of a mixed-species flock, searching for both fruit and insects. Yellow-scarfed Tanager's genus name, Iridosornis, is derived from Greek and means rainbow bird (iris - rainbow; ornis - bird) . The specific epithet reinhardti honors 19th century biologist Johannes Theodor Reinhardt (Jobling 2010). In Spanish, the common name of this species is Tangara de Reinhardt (Hilty 2011, de Juana et al. 2012).
