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.
The genus name is derived from the Greek khaite, for long flowing hair, and oura, for tail, referring to the stiff feathers projecting from the end of the tail. [1]
A fossil species, Chaetura baconica, was described from Late Miocene deposits of Hungary. [2]
The chimney swift is a bird belonging to the swift family Apodidae. A member of the genus Chaetura, it is closely related to both Vaux's swift and Chapman's swift; in the past, the three were sometimes considered to be conspecific. It has no subspecies. The chimney swift is a medium-sized, sooty gray bird with very long, slender wings and very short legs. Like all swifts, it is incapable of perching, and can only cling vertically to surfaces.
The little swift, is a small species of swift found in Africa and southwestern Asia, and are vagrants and local breeders in southern Europe. They are found both in urban areas and at rocky cliffs where they build nests in a way typical of all members of the order Apodiformes. The genus name Apus is Latin for a swift, thought by the ancients to be a type of swallow without feet. The Latin specific affinis means similar to or related to, but in this case the species that the little swift supposedly resembles is not clear from the description. A population formerly considered to be an eastern subspecies of little swift is now separated as a distinct species, the house swift.
The pallid swift is a swift. Swifts have very short legs which they use only for clinging to vertical surfaces. The genus name Apus is Latin for a swift, thought by the ancients to be a type of swallow with no feet, and pallidus is Latin for "pale". They never settle voluntarily on the ground. Swifts spend most of their lives in the air, living on the insects they catch in their beaks. They drink on the wing.
The Pacific swift or fork-tailed swift is a species of bird that is part of the Swift family. It breeds in eastern Asia. It is strongly migratory, spending the northern hemisphere's winter in Southeast Asia and Australia. The general shape and blackish plumage recall its relative, the common swift, from which it is distinguished by a white rump band and heavily marked underparts. The sexes are identical in appearance, although young birds can be identified by pale fringes to the wing feathers that are absent in adults. This swift's main call is a screech typical of its family. It is one of a group of closely related Asian swifts formerly regarded as one species.
The band-rumped swift is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found from Panama south through Colombia into Ecuador, east from Venezuela into the Guianas and Brazil, and on Trinidad.
The grey-rumped swift or gray-rumped swift is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found in Honduras, Nicaragua, Costa Rica, and Panama; in every mainland South American country except Chile, French Guiana, Suriname, and Uruguay; in Trinidad and Tobago; and on Grenada.
The short-tailed swift is a bird in the Apodidae, or swift family.
The Andean swift is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found in Argentina, Bolivia, Chile, and Peru.
Chapman's swift is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found in Bolivia, Brazil, Colombia, French Guiana, Guyana, Panama, Peru, Suriname, Trinidad, Venezuela, and possibly Ecuador.
The pale-rumped swift is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.
The Costa Rican swift is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found in Costa Rica and Panama.
The Lesser Antillean swift is a species a species of bird in subfamily Apodinae of the swift family Apodidae. It is found on Dominica, Guadeloupe, Martinique, Saint Lucia, Saint Vincent, and possibly Nevis.
Sick's swift is a species of swift in the family Apodidae. It was previously considered conspecific with the smaller ashy-tailed swift, but a study published in 1997 found that Sick's swift was closer to the chimney swift. The English name commemorates the German-born ornithologist Helmut Sick who studied South American birds. It is a migratory species that breeds in central South America and overwinters in northern South America. The IUCN has listed it as being of "Least Concern".
The ashy-tailed swift or Andre's swift is a Vulnerable species of bird in subfamily Apodinae of the swift family Apodidae. It is endemic to northern and central Venezuela.
Salim Ali's swift is a small bird, superficially similar to a house martin. It is, however, completely unrelated to those passerine species, since swifts are in the order Apodiformes. The resemblances between the groups are due to convergent evolution reflecting similar life styles.
Vaux's swift is a small swift native to North America, Central America, and northern South America. It was named for the American scientist William Sansom Vaux.
The Apodinae are a subfamily of swifts and contain the following species:
