Chapin's free-tailed bat (Chaerephon chapini) is a species of bat in the family Molossidae. It is found in central and southern Africa.
Chapin's free-tailed bat is a relatively small species, measuring 8 to 12 cm (3.1 to 4.7 in) in length, including a 3 cm (1.2 in) tail, and weighing around 10 g (0.35 oz). The body has pale cinnamon-brown or greyish fur that fades to near-white towards the middle of the belly. The wings are white or pale brown in colour. A distinctive crest of hair rises from a small lappet between the ears. This is relatively small and bland in females, but is three times larger, at up to 15 mm (0.59 in) long, and striking bi-coloured in males, being reddish chestnut at the base, and whitish above. [2] The crest is especially well developed in breeding males, and helps to disperse scent from a gland at its base. [3]
Chapin's free-tailed bat is found across much of central and southern Africa, between Ethiopia and South Sudan in the northeast, the Republic of the Congo in the northwest, and northern Namibia, Botswana, and Zimbabwe in the south. An isolated population is also known from Ghana and the Ivory Coast. Within this region it inhabits savannah habitats, river valleys and woodland. [1]
The bat is insectivorous, feeding in flight. Its echolocation calls last five to ten milliseconds, and sweep from 27 down to 19 kHz. [2]
The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their genus. Their strong flying form allows them to fly 60 miles per hour using tail winds and at altitudes over 10,000 feet. This makes them unique among bats, as they are the only bat family that withstands the elevation. They are widespread, being found on every continent except Antarctica. They are typically found in caves, abandoned mines, or tunnels.
The dwarf dog-faced bat is a species of free-tailed bat from South America. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Paraguay and Uruguay, typically at lower elevations. It is one of two species in the genus Molossops, the other being the rufous dog-faced bat. Three subspecies are often recognized, though mammalogist Judith Eger considers it monotypic with no subspecies. It is a small free-tailed bat, with a forearm length of 28.9–32.5 mm (1.14–1.28 in) and a weight of 5–8 g (0.18–0.28 oz); males are larger than females. It is brown, with paler belly fur and darker back fur. Its wings are unusual for a free-tailed bat, with exceptionally broad wingtips. Additionally, it has low wing loading, meaning that it has a large wing surface area relative to its body weight. Therefore, it flies more similarly to a vesper bat than to other species in its own family. As it forages at night for its insect prey, including moths, beetles, and others, it uses two kinds of frequency-modulated echolocation calls: one type is to navigate in open areas and to search for prey, while the other type is used for navigating in cluttered areas or while approaching a prey item.
The Natal free-tailed bat is a species of bat in the family Molossidae, the free-tailed bats. It is endemic to the island of Mauritius. It is known from fewer than five locations in its range, but it is common at a few sites. It roosts in caves, and it is considered to be an endangered species due to disturbance of its cave habitat.
Ansorge's free-tailed bat is a species of bat in the family Molossidae native to sub-Saharan Africa. It is named for W.J. Ansorge, who collected the first formally described specimen.
The gland-tailed free-tailed bat is a species of bat in the family Molossidae. Its natural habitats are subtropical or tropical moist montane forests, dry savanna, and caves.
The Fijian mastiff bat, also known as the Fijian free-tailed bat, is a species of bat in the family Molossidae. It is found in Fiji and Vanuatu. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation. This species is currently listed as endangered and considered a species of special concern due to habitat fragmentation and cave disturbance. The Fijian free-tailed bat is endemic to Fiji and Vanuatu islands. This species was previously documented on the islands of Taveuni and Vanua Levu, current research indicates possible small fragmented populations inhabiting both islands. Only two insectivorous bats occupy Fiji, the Pacific sheath-tailed bat and the Fijian free-tailed bat. Both species consume night flying insects, foraging high above the canopy.
The northern free-tailed bat is a species of bat in the family Molossidae. It is found in Indonesia and Malaysia.
The Nigerian free-tailed bat is a species of bat in the family Molossidae. It is native to two widely separated parts of Africa, and is sometimes considered to represent two separate species.
The little free-tailed bat is a species of the genus Chaerephon in the family Molossidae. It is widely distributed across Africa and islands around the continent.
The Solomons mastiff bat is a species of bat in the family Molossidae. It is endemic to the Solomon Islands.
The São Tomé free-tailed bat is a species of bat in the family Molossidae. It is endemic to São Tomé and Príncipe. Its natural habitats are dry savanna, moist savanna, and plantations. It is threatened by habitat loss. Only three individuals have ever been documented.
The hairless bat, also called the naked bulldog bat and greater naked bat, is a species of bat in the family Molossidae. The generic name Cheiromeles comes from the Greek word cheir and the species name is derived from the Latin torques.
Roberts's flat-headed bat is a species of free-tailed bat native to southern Africa. It is the only species in the genus Sauromys. The scientific name translates as "rock loving lizard-mouse", while the common name honours Austin Roberts, who first described the species.
The Egyptian free-tailed bat, also known as Egyptian guano bat or Egyptian nyctinome, is a species of bat in the family Molossidae.
The blunt-eared bat or Peruvian crevice-dwelling bat is a species of bat in the family Molossidae. It is monotypic within the genus Tomopeas and subfamily Tomopeatinae. It is endemic to Peru, where it is considered critically endangered. It is threatened by habitat loss.
Chaerephon is a genus of Old World free-tailed bats in the family Molossidae. Molecular sequence data indicates that Chaerephon, Mops and Tadarida are not monophyletic taxa. The closest relatives of Chaerephon jobimena of Madagascar are Tadarida aegyptiaca of Africa and southwest Asia, and Tadarida brasiliensis of the Americas, which form a clade believed to be about 9.8 million years old. However, the grouping of Chaerephon minus C. jobimena plus Mops was found to be monophyletic.
Mops is a genus of bats in the family Molossidae. Molecular sequence data indicates that Mops and Chaerephon are not monophyletic taxa. However, the grouping of Chaerephon and Mops was found to be monophyletic when excluding C. jobimena.
Gallagher's free-tailed bat is a free-tailed bat endemic to the Democratic Republic of the Congo. Only one individual has ever been documented.
Chaerephon jobimena, commonly known as the black and red free-tailed bat, is a species of bat in the family Molossidae. It is endemic to western Madagascar. With a forearm length of 45 to 48 mm, C. jobimena is somewhat larger than other Malagasy bats assigned to Chaerephon, but similar in size to Tadarida aegyptiaca.
Chaerephon atsinanana is a free-tailed bat found on Madagascar. It was considered a subspecies of the little free-tailed bat until 2010. During the day, they are known to roost in man-made structures such as the roofs or attics of buildings.
