The little swift (Apus affinis) belongs to the family Apodidae under the order Apodiformes.

Little swift taxonomy

The family Apodidae comprises highly aerial birds which are amongst the fastest birds. These species have short and small legs. The name Apodidae, is derived from the Greek ἄπους (ápous), meaning "footless".

The family Apodidae is normally grouped into two subfamilies, four tribes and eighteen genera. The genus Apus comprises twenty species and is the second largest genus.

The type species was given the binomial name Hirundo apus by the Swedish naturalist Carl Linnaeus in 1758. In 1777 based on tautonymy, the Italian naturalist Giovanni Antonio Scopoli (Johannes Antonius Scopolius) (3 June 1723 – 8 May 1788) had erected the genus name Apus.

A controversy rose out of a small crustacean being given the genus name Apus in 1801. In 1958, the International Commission on Zoological Nomenclature ended the controversy.

Origin, geographical range and distribution

The little swift species are distributed in India, Bangladesh, Sri Lanka, Pakistan, parts of Middle East, parts of central Asia and Africa.

Vagrant little swifts have been observed in Australia, Bulgaria, Greece, Sweden, United Kingdom, Ireland, Italy, Portugal, Maldives, Malta and Seychelles.

In India, these little swift species are distributed in the states of Kerala, Tamilnadu, Karnataka, Goa, Andhra Pradesh, Telangana, Maharashtra, Odisha, Madhya Pradesh, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Jharkhand, Chhattisgarh, West Bengal, Gujarat, Rajasthan, Punjab, Haryana, Jammu and Kashmir and Bihar.

The little swift nominate subspecies A. a. affinis is distributed in Somalia, Kenya, Tanzania, Malawi, Mozambique, Madagascar and south of Himalayas in India. Some populations winter in India and some in Africa.

The little swift subspecies A. a. singalensis is distributed in southern India and Sri Lanka. The subspecies A. a. theresae is distributed in Angola, Zambia, Zimbabwe, Botswana, Namibia and South Africa.

The little swift subspecies A. a. bannermani is distributed in Bioko, Príncipe and São Tomé, in Gulf of Guinea. The subspecies A. a. aerobates is distributed in central Africa, from Mauritania to Somalia and along eastern Africa.

The little swift subspecies A. a. galilejensis is distributed in northwest Africa, Sudan, Eritrea, Ethiopia and northwest Somalia, Yemen, Saudi Arabia, Israel, Jordan, Lebanon, Syria, Turkey, Iran, Pakistan, Afghanistan, Tajikistan and Uzbekistan.

The Important Bird and Biodiversity Areas (IBA) in Turkey are Dicle Valley, Southern Euphrates Valley and Birecik Plains.

Ecosystem and habitat

These little swift species have low forest dependence. These species normally occur in altitudes from 0 to 3000 meters. The artificial ecosystems of these species include rural and urban human habitations.

The natural ecosystems of these little swift species include tropical and subtropical mangrove vegetations, tropical and subtropical dry grasslands, tropical and subtropical moist lowland forests, dry savanna, Mediterranean-type shrublands and tropical and subtropical dry shrublands.

Diet and feeding behavior

The diet of the little swift consists mainly of flying insects. Aeroplankton (or aerial plankton), flies, airborne spiders, moths, butterflies, flying termites and ants, dragonflies, locust, cicadas, grasshoppers, crickets and mantises are their primary food.

These little swift species are excellent aerial foragers, hawking insects on the wing. They are exceptionally agile in flight and drink by skimming the water surface while flying. The hatchlings are fed with food balls, a mass of insects bound together by saliva.

Reproduction and breeding habits

The breeding season of these little swift species is from February to May and August to October in Mauritania. The breeding season is from October to July in Senegal and Gambia. They lay year-round in West African rainforest areas.

The nominate little swift species breed year-round in India, except cold winter months. The laying season in Sri Lanka is from March to July. In Pakistan these species breed during February and March.

The nesting sites of the little swift include man-made structures, abandoned swallow nests and cliff sites. These birds are colonial breeders and typically up to 30 nests can be seen together. Sometimes two or three birds lay eggs in one nest.

The hemispherical nest-bag is made of grass, down feathers, small twigs and feathers glued and fixed to the vertical surface with saliva. The nest is sturdy; though the nest appears untidy, it is neat and smooth inside.

The little swift clutch may contain 1-3 white eggs. Both the parents incubate the eggs for 22-24 days. In some cases a second clutch is laid after the fledging of the earlier brood. Egg laying may get completed within ten days in a colony.

Migration and movement patterns

The little swift species are partially migrant birds.

The little swift populations in western Palearctic region as well as the southern African populations are partially or fully migratory, moving to tropical and subtropical regions. The rest of the populations are resident.

Post breeding, the juvenile swifts may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.

Conservation and survival

The global population size of the little swift (Apus affinis) has not been quantified. The overall population trend of these species is reported to be increasing.

Throughout its range this swift species is reported to be scarce to locally abundant. The generation length is 12.5 years. Its distribution size is about 60,600,000 sq.km.

Habitat degradation, habitat loss and sharp fall in the flying insect population due excessive use of farm chemicals are the main threats that may endanger the survival of these swift species.

IUCN and CITES status

The little swift (Apus affinis) does not approach the thresholds for being Vulnerable, either under the range size criterion, or under the population trend criterion or under the population size criterion.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated the swift species and has listed it as of "Least Concern". The CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Not Evaluated’ for little swift (Apus affinis).

Taxonomic classification   ⇿   Pictures
The Pacific swift (Apus pacificus) belongs to the family Apodidae under the order Apodiformes.

The genus Apus contains twenty extant species and four fossil species. The Apus spp. are the fastest of birds. They can cruise at a maximum speed of 112 km per hour. It is estimated that these species can cover above 200,000 km. in a year.

These birds have large wingtip bones. They can alter the shape and area of their wings to drive maximum efficiency in flight. Their ability to rotate their wings from the base makes the wing to remain rigid and fully extended.

They are able to deriving power on both upstroke and downstroke, increasing control and maneuverability in air.
