They are among the fastest birds in the world. They resemble swallows, to which they are not related, but have shorter tails and sickle-shaped wings. Swifts spend most of their life aloft, have very short legs and use them mostly to cling to surfaces.
Taxonomy
The genus Apus was erected by the Italian naturalist Giovanni Antonio Scopoli in 1777 based on tautonymy and the common swift which had been given the binomial name Hirundo apus by the Swedish naturalist Carl Linnaeus in 1758.[2][3][4] The name Apus is Latin for a swift, thought by the ancients to be a type of swallow with no feet (from Ancient Greek α, a, "without", and πούς, pous, "foot").[5]
Before the 1950s, there was some controversy over which group of organism should have the genus name Apus.[6] In 1801, Bosc gave the genus name Apus to the small crustacean organisms known today as Triops, and later authors continued to use this term. Keilhack suggested (in 1909) that this was incorrect since there was already an avian genus named Apus by Scopoli in 1777. The controversy was ended in 1958 when the International Commission on Zoological Nomenclature (ICZN) ruled against the use of the genus name Apus for the crustaceans and recognized the name Triops.[7]
