The Perijá metaltail (Metallura iracunda) is an Endangered species of hummingbird in the "coquettes", tribe Lesbiini of subfamily Lesbiinae.

[3] It is closely related to the Tyrian metaltail (M. tyrianthina) and is sympatric with one of its subspecies.

It has an emerald green gorget and a slightly forked glittering ruby red tail.

It inhabits the varied landscapes of the different peaks within the mountain range, including open bushy terrain, karstic elfin forest, bamboo stands, grassy páramo, and areas of sandstone outcrops.

The Perijá metaltail's vocalizations have not been described, but Xeno-canto and Cornell University's Macaulay Library have a few recordings.
