The sooty mustached bat (Pteronotus quadridens) is a species of bat in the family Mormoopidae. It is found in throughout the Greater Antilles, in Cuba, Hispaniola (the Dominican Republic and Haiti), Jamaica, and Puerto Rico.
The sooty mustached bat is the smallest species in the genus Pteronotus . Color phases in this bat are indicators of age differences or bleaching due to high concentrations of ammonia in the roost. As a result, color ranges from grayish brown to yellowish brown with some individuals reaching an orange-brown phase. The body is completely covered in fur except for the wings and tail membrane. The length of mandible is 8–9 millimetres (0.31–0.35 in) and their forearm is less than 41 millimetres (1.6 in) in length. The margin above nostril is lobulated and slightly convex. [3]
Sooty mustached bats are monestrous and uniparous most of the time with twinning rarely occurring. Based on the testicular size, mating begins in January and most females are pregnant in May. The pregnant female undergoes an increase in body mass of 38%. The largest embryo reported weighed 1.8 grams (0.063 oz), or 30.2% of the female's body mass. Throughout the breeding season, either males or females might disappear completely into caves. However, there is a marked shift in adult sex ratio favoring females. This suggests sexual segregation during the maternity period. [4]
Pteronotus quadridens roost exclusively in caves. [1] [4] They are one of the most common bats in Cuba and Puerto Rico. [1] [4] All currently known fossils of Pteronotus quadridens are believed to be from late Pleistocene or Holocene epochs. The ancestors of Pteronotus quadridens are also expected to have originated on the Central American mainland. [4] [5]
Pteronotus quadridens is an insectivorous bat feeding almost exclusively on flying insects. They start foraging approximately 10 minutes before sunset and continue to do so overnight. Almost all foraging is done in flight. [4] [6]
There are two respective patterns of echolocation calls in the field. First they call with quasi-constant frequency at 81–84 kHz, followed by a downward, frequency-modulated (FM) call. When the bats are flying in confined spaces, the call duration will be shorter and the bandwidth higher than the ones emitted during the search calls in the field. [6]
Pteronotus quadridens are susceptible to predation by diurnal birds since they are the first to leave just after the sunsets. Raptors such as the American kestrel, red-tailed hawk and merlin are among a few of the sooty mustached bat’s predators. [4] [7]
The New World leaf-nosed bats (Phyllostomidae) are found from southern North America to South America, specifically from the Southwest United States to northern Argentina. They are ecologically the most varied and diverse family within the order Chiroptera. Most species are insectivorous, but the phyllostomid bats include within their number true predatory species and frugivores. For example, the spectral bat, the largest bat in the Americas, eats vertebrate prey, including small, dove-sized birds. Members of this family have evolved to use food groups such as fruit, nectar, pollen, insects, frogs, other bats, and small vertebrates, and in the case of the vampire bats, even blood.
The Mexican free-tailed bat or Brazilian free-tailed bat is a medium-sized bat native to the Americas, so named because its tail can be almost half its total length and is not attached to its uropatagium. It has been claimed to have the fastest horizontal speed of any animal, reaching top ground speeds over 99 mph (160 km/h). It also flies the highest among bats, at altitudes around 3,300 m (10,800 ft).
The big brown bat is a species of vesper bat distributed widely throughout North America, the Caribbean, and the northern portion of South America. It was first described as a species in 1796. Compared to other microbats, the big brown bat is relatively large, weighing 15–26 g (0.53–0.92 oz) and possessing a wingspan of 32.5–35 cm (12.8–13.8 in).
The common pipistrelle is a small pipistrelle microbat whose very large range extends across most of Europe, North Africa, South Asia, and may extend into Korea. It is one of the most common bat species in the British Isles. In Europe, the northernmost confirmed records are from southern Finland near 60°N.
The family Mormoopidae contains bats known generally as mustached bats, ghost-faced bats, and naked-backed bats. They are found in the Americas from the Southwestern United States to Southeastern Brazil.
Parnell's mustached bat is an insectivorous bat native to the Americas. It ranges from southern Sonora, Mexico, south to Brazil. It has a wider historical range; fossil specimens have been collected on the island of New Providence in the Bahamas.
The greater noctule bat is a rare carnivorous bat found in Europe, West Asia, and North Africa. It is the largest and least studied bat in Europe with a wingspan of up to 46 centimetres (18 in) and is one of the few bat species to feed on passerine birds. Greater noctule bats are the only bat species to hunt birds on the wing rather than when roosting. The greater noctule bat has wings adapted for open-air hunting and uses echolocation frequencies above the hearing range of birds.
The pallid bat is a species of bat that ranges from western Canada to central Mexico. It is the sole species of its genus and is closely related to Van Gelder's bat, which is sometimes included in Antrozous. Although it has in the past been placed in its own subfamily (Antrozoinae) or even family (Antrozoidae), it is now considered part of the subfamily Vespertilioninae and the tribe Antrozoini.
Wagner's mustached bat is a bat species from South and Central America. It is one of the few New World bats species known to perform Doppler shift compensation behavior.
The lesser sac-winged bat or lesser white-lined bat is a bat species of the family Emballonuridae from South and Middle America.
Davy's (lesser) naked-backed bat is a small, insect-eating, cave-dwelling bat of the Family Mormoopidae. It is found throughout South and Central America, including Trinidad, but not Tobago, Guyana, Suriname, or French Guiana. Specimens of this bat had been found infected with rabies in Trinidad during the height of that island's vampire-bat-transmitted rabies epidemic of the early half of the 20th century, but not in recent times.
The common noctule is a species of insectivorous bat common throughout Europe, Asia, and North Africa.
Waterhouse's leaf-nosed bat is a species of big-eared bat in the family Phyllostomidae. It is found in the Greater Antilles in the Cayman Islands, Cuba, Hispaniola and Jamaica, as well as Mexico south to Guatemala.
Leach's single leaf bat, also known as Greater Antillean long-tongued bat, is a species of bat in the family Phyllostomidae. It is found in the southern Bahamas and in all the Greater Antilles. It forms large colonies, with up to a few hundred thousand individuals, and feeds on a relatively wide variety of food items including pollen, nectar, fruit and insects.
The Antillean ghost-faced bat is a species of bat in the family Mormoopidae. It is found in the Greater Antilles: Cuba, Hispaniola Jamaica, and Puerto Rico.
Macleay's mustached bat is a species of bat in the family Mormoopidae. It is found in Cuba and Jamaica, and is threatened by habitat loss. The species is named for William Sharp Macleay, who collected the type specimen.
The little brown bat or little brown myotis is an endangered species of mouse-eared microbat found in North America. It has a small body size and glossy brown fur. It is similar in appearance to several other mouse-eared bats, including the Indiana bat, northern long-eared bat, and Arizona myotis, to which it is closely related. Despite its name, the little brown bat is not closely related to the big brown bat, which belongs to a different genus.
The Florida bonneted bat or Florida mastiff bat is a species of bat in the genus Eumops, the bonneted bats or mastiff bats. Until recently, it was classified as a subspecies of Wagner's bonneted bat. It is endemic to southern Florida in the United States. This species has one of the smallest geographical distributions of any New World bat. It has been called "one of the most critically endangered mammal species in North America". It is protected under the Endangered Species Act.
The pristine mustached bat is an extinct Late Quaternary species of bat in the endemic Neotropical family Mormoopidae. It was distributed in Cuba and possibly Florida.
