Chaetura
Genus of birds
From Wikipedia, the free encyclopedia
Chaetura is a genus of needletail swifts found in the Americas. Although they resemble swallows, the two are not at all closely related; this is instead a result of convergent evolution. Some members of Chaetura are long-distance migrants, while others are year-round residents.

Taxonomy
The genus Chaetura was introduced in 1826 by the English naturalist James Francis Stephens who listed several species in the genus but did not specify a type.[1] In 1829 the English zoologist William Swainson selected the type as Chaetura pelasgia Stevens (sic). This is a junior synonym of Hirundo pelagica Linnaeus the chimney swift.[2][3] The genus name combines the Ancient Greek χαιτη/khaitē meaning "long flowing hair" with ουρα/oura meaning "tail".[4]
