Swiftlets are birds from the four genera Aerodramus, Collocalia, Hydrochous and Schoutedenapus, which form the tribe Collocaliini within the swift family Apodidae. The group contains around thirty species mostly confined to southern Asia, south Pacific islands, and northeastern Australia, all within the tropical and subtropical regions. They are in many respects typical members of the Apodidae, having narrow wings for fast flight, with a wide gape and small reduced beak surrounded by bristles for catching insects in flight. What distinguishes many but not all species from other swifts and indeed almost all other birds is their ability to use a simple but effective form of echolocation to navigate in total darkness through the chasms and shafts of the caves where they roost at night and breed.
Aerodramus is a genus of small, dark, cave-nesting birds in the Collocaliini tribe of the swift family. Its members are confined to tropical and subtropical regions in southern Asia, Oceania and northeastern Australia. Many of its members were formerly classified in Collocalia, but were first placed in a separate genus by American ornithologist Harry Church Oberholser in 1906.
The Himalayan swiftlet is a small swift. It is a common colonial breeder in the Himalayas and Southeast Asia. Some populations are migratory.
The edible-nest swiftlet, also known as the white-nest swiftlet, is a small bird of the swift family which is found in Southeast Asia. Its opaque and whitish bird nest is made exclusively of solidified saliva and is the main ingredient of bird's nest soup, a delicacy of Chinese cuisine. Germain's swiftlet is now treated as conspecific with this species.
Collocalia is a genus of swifts, containing some of the smaller species termed "swiftlets". Formerly a catch-all genus for these, a number of its former members are now normally placed in Aerodramus.
The glossy swiftlet is a species of swift in the family Apodidae. It is found on the Indonesian island of Sulawesi and eastwards to New Guinea, the Bismarck Archipelago and the Solomon Islands.
The Mascarene swiftlet or Mauritius swiftlet is a species of swift in the family Apodidae. It is found in Mauritius and Réunion, and the populations on the two islands have recently been confirmed to differ subspecifically. The nominate race francicus is found on Mauritius and the recently described race saffordi occurs on Réunion. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical high-altitude shrubland, subtropical or tropical high-altitude grassland, caves, arable land, and heavily degraded former forest. It is threatened by habitat loss.
The Moluccan swiftlet is a small bird in the swift family Apodidae that is found on Sulawesi and on the Maluku Islands in Indonesia. Two subspecies, the Sulawesi swiftlet and the Seram swiftlet, have sometimes been considered as separate species.
The cave swiftlet or linchi swiftlet is a species of swift in the family Apodidae. It is found on the Indonesia islands of Sumatra, Java and Bali. It is a woodland species and nests in caves. The Bornean swiftlet was considered a subspecies, but is now usually considered distinct.
The Philippine swiftlet is a species of swift in the family Apodidae. It is endemic to the Philippines.
The pygmy swiftlet is a species of swift in the family Apodidae. It is endemic to the Philippines.
The Christmas Island swiftlet, also known as the Christmas glossy swiftlet or the Christmas cave swiftlet, is a small bird in the swift family Apodidae. It is endemic to Christmas Island, an Australian territory in the eastern Indian Ocean. It was formerly commonly treated as a subspecies of the glossy swiftlet.
The Bornean swiftlet, also referred to as the Kinabalu 'linchi' swiftlet, is a small bird in the swift family Apodidae. It is endemic to the northern mountains of the island of Borneo. It has variously been considered a subspecies of the glossy swiftlet or the cave swiftlet, and in 2008 was split from the latter as a full species C. dodgei.
The grey-rumped swiftlet or grey-rumped swiftlet, is a small bird in the swift family Apodidae. It is endemic to some islands in the Philippines.
The Apodinae are a subfamily of swifts and contain the following species:
The satin swiftlet is a small bird in the swift family Apodidae. It is endemic to the Santa Cruz Islands, Vanuatu, New Caledonia and the Loyalty Islands in the southwestern Pacific Ocean. It was formerly treated as a subspecies of the glossy swiftlet.
The drab swiftlet is a small bird in the swift family Apodidae. It is endemic to the Lesser Sunda Islands in Indonesia. It was formerly treated as a subspecies of the glossy swiftlet.
The plume-toed swiftlet is a small bird in the swift family Apodidae. It is found on some eastern Indian Ocean islands, the Malay Peninsula, Sumatra, and lowland Borneo.
The Tenggara swiftlet is a small bird in the swift family Apodidae. It is endemic to the western Lesser Sunda Islands of Indonesia.
