Yellow-throated Tanager is a common species, widely distributed along the east slope of the Andes from southern Colombia to extreme southeastern Peru, and is an inhabitant of the dense understory of humid montane forest. Yellow-throated Tanager is replaced to the north by the similar Purplish-mantled Tanager (Iridosornis porphyrocephala); these two, which formerly were considered by some authors to be a single species, generally occur at slightly lower elevations than other Iridosornis. Both have more or less identical vocalizations, behavior, and habitat preferences. In plumage, however, Yellow-throated Tanager differs from Purplish-mantled Tanager in its much paler blue upperparts and its pale cinnamon (not blue) underparts. Like all its congeners, Yellow-throated Tanager typically travels in small groups of its own species that often associate with mixed species foraging flocks. The genus name Iridosonis derives from the Latin words iris, meaning rainbow, and ornis, meaning bird. The specific epithet analis is Latin for anus, and refers to the chestnut-colored undertail covers (Jobling 2010). The common name for this species in Spanish is Tangara Goliamarilla (Hilty 2011, de Juana et al. 2012).
