These birds live in the Andes mostly at high altitudes. Their plumage is mainly blue and all of them have contrasting patches of yellow.[1]

Taxonomy and species list

The genus Iridosornis was introduced in 1844 by the French naturalist René Lesson with the golden-crowned tanager as the type species.[2][3] The name combines the Ancient Greek iris meaning "rainbow" with ornis meaning "bird".[4] A molecular phylogenetic study published in 2014 found that this genus had a sister relationship to the vermilion tanager which is placed in its own monospecific genus Calochaetes.[5]

The genus contains five species:[6]

Image	Scientific name	Common Name	Distribution
	Iridosornis porphyrocephalus	Purplish-mantled tanager	Colombia and Ecuador
	Iridosornis analis	Yellow-throated tanager	Colombia, Ecuador, and Peru
	Iridosornis jelskii	Golden-collared tanager	Bolivia and Peru
	Iridosornis rufivertex	Golden-crowned tanager	Colombia, Ecuador, Peru, and Venezuela
	Iridosornis reinhardti	Yellow-scarfed tanager	Peru
