The Pacific Swift (Apus pacificus), or Fork-tailed 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.
The Little Swift (Apus affinis), or House Swift, is a small bird, superficially similar to a Barn Swallow or 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. The eastern race, House Swift, is sometimes considered a separate species, Apus nipalensis.
The Uniform Swiftlet (Collocalia vanikorensis), also known as the Vanikoro or Lowland Swiftlet, is a gregarious, medium-sized swiftlet with a shallowly forked tail. The colouring is dark grey-brown, darker on the upperparts with somewhat paler underparts, especially on chin and throat. This species is widespread from the Philippines through Wallacea, New Guinea and Melanesia. It forages for flying insects primarily in lowland forests and open areas. It nests in caves where it uses its sense of echolocation, rare in birds, to navigate.
The White-throated Needletail (Hirundapus caudacutus), also known as Needle-tailed Swift or Spine-tailed Swift, is a large swift. It is the fastest-flying bird in level, flapping flight, being capable of 170 km/h (105mph). The flight is impressively fast,[citation needed] even compared to other swifts.
