Red-tailed Comet

About the Red-tailed Comet

The red-tailed comet (Sappho sparganurus) is a medium-sized hummingbird belonging to tribe Lesbiini of subfamily Lesbiinae, the "coquettes". It is found in Argentina and Bolivia and possibly Chile and Peru. The red-tailed comet was formally described in 1812 by the English naturalist George Shaw under the binomial name Trochilus sparganurus. The type locality is Bolivia. Some early twentieth century authors placed it in genus Lesbia. The red-tailed comet is now the only species in genus Sappho that was introduced in 1849 by the German naturalist Ludwig Reichenbach. The genus name refers to Sappho, an ancient Greek poet of Lesbos. The specific epithet sparganurus combines the Ancient Greek σπαργανόω/spargaō meaning 'to wrap' and ουρά/oura meaning 'tail'.

The red-tailed comet has two subspecies, the nominate S. s. sparganurus (Shaw, 1812) and S. s. sapho (Lesson, R, 1828). In the early twentieth century at least one author treated the two as individual species. In at least part of its range it is known in the local Quechua language as Q'ori Kenti (lit. 'golden hummingbird'). It is called the picaflor cometa in Argentina.
