The bat family Noctilionidae, commonly known as bulldog bats or fishing bats, is represented by two extant species, the greater and the lesser bulldog bats, as well as at least one fossil species, Noctilio lacrimaelunaris, from the Miocene of Argentina. The naked bulldog bat does not belong to this family, but to the family Molossidae, the free-tailed bats. They are found near water in the Neotropics, from Mexico to Argentina and also in the Caribbean islands. In these areas they can be found roosting in groups within hollow trees, caves, manmade homes, or other openings with enough space. While the two species exhibit different social and foraging behaviors both tend to return to a main roosting spot while also visiting other alternative roosting spots.
The greater bulldog bat or fisherman bat is a species of fishing bat native to Latin America. The bat uses echolocation to detect water ripples made by the fish upon which it preys, then uses the pouch between its legs to scoop the fish up and its sharp claws to catch and cling to it. It is not to be confused with the lesser bulldog bat, which, though belonging to the same genus, merely catches water insects, such as water striders and water beetles.
Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, Rhinolophus, which has about 106 species, the extinct genus Palaeonycteris has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania.
The gray bat is a species of microbat endemic to North America. It once flourished in caves all over the southeastern United States, but due to human disturbance, gray bat populations declined severely during the early and mid portion of the 20th century. 95% of gray bats now hibernate in only 15 caves. M. grisescens has been listed as federally endangered by the U.S. Fish and Wildlife Service since 1976, and is protected under the Endangered Species Act. Gray bat populations were estimated at approximately 2 million bats around the time they were placed on the Endangered Species list. By the early 1980s populations of gray bats dropped to 1.6 million. With conservation efforts in place, in 2004, gray bat populations were estimated to have reached 3.4 million.
The New Zealand lesser short-tailed bat is a small-sized omnivorous mammal endemic to the islands of New Zealand. It is one of two extant and three overall terrestrial mammal species unique to New Zealand. Its closest relative, the New Zealand greater short-tailed bat, was last seen in 1965 and is presumed extinct due to intense predation from ship rats introduced in the last few centuries. These bats are also commonly referred to as pekapeka, their Māori-language name. Lesser short-tailed bats have unique adaptations that differentiate them from bats found in other parts of the world. For example, they are fully capable of moving along the ground to search for food, and the males sing to attract partners, taking turns to do so. Lesser short-tailed bats are a vulnerable species, so extensive conservation work and research are being done to prevent extinction.
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.
Chalinolobus tuberculatus, known more commonly as the New Zealand long-tailed bat, the long-tailed wattle bat or pekapeka tou-roa, is a small insectivorous mammal within the genus Chalinolobus. The long-tailed bat is one of 7 species belonging to the genus Chalinolobus, which are commonly referred to as “wattled bats,” “pied bats” and “long-tailed bats." The genus Chalinolobus is characterised by fleshy lobes located on their lower lips and at the bottom of their ears. Some zoologists claim there is overlap between the Chalinolobus genus and the Glauconycteris genus.
The northern ghost bat is a bat species from South America, Trinidad, and Central America. It is a relatively rare, completely white, insectivorous bat, with an unusual sac at the base of its tail.
The lesser sac-winged bat or lesser white-lined bat is a bat species of the family Emballonuridae from South and Middle America.
The long-legged bat is a member of the Phyllostomidae family in the order Chiroptera. Both males and females of this species are generally small, with wingspans reaching 80mm with an average weight ranging between 6 and 9 grams. The facial structure of these bats includes a shortened rostrum with a prominent noseleaf. The most defining feature of these bats however, is their long posterior limbs that extend farther than most Phyllostomidae bats. At the ends of these hind legs, the long-legged bat has abnormally large feet equipped with strong claws.
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 large slit-faced bat is a species of slit-faced bat with a broad distribution in forest and savanna habitats in West, Central, and East Africa. N. marica, is the available name for the southern savanna species if it is recognized as distinct from this species.
The Egyptian slit-faced bat is a species of slit-faced bat broadly distributed throughout Africa and the Middle East. It is a species of microbat in the family Nycteridae. Six subspecies are known.
The Hawaiian hoary bat, also known as ʻōpeʻapeʻa, is a species of bat endemic to the islands of Hawaiʻi. The Hawaiian hoary bat occupies the major Hawaiian islands, making it the only extant and native terrestrial mammal in the islands. Some studies report that the mainland hoary bat lives in sympatry on the Hawaiian Islands alongside the Hawaiian hoary bat, although this is disputed. The Hawaiian hoary bat was officially named the state land mammal of Hawaiʻi in 2015. It is a federally listed endangered taxon of the United States.
The cave myotis is a species of vesper bat (Vespertilionidae) in the genus Myotis.
The Mauritian tomb bat is a species of sac-winged bat in the family Emballonuridae that is found in central and southern Africa and Madagascar. It was discovered in 1818 by Étienne Geoffroy Saint-Hilaire, and is characterized by an all-white ventral surface, grizzled dorsal coloration, and conical face. It has exceptionally good eyesight, a trait which is common in old world bats and enables it to find roosting locations. It has adapted itself to a wide range of habitats including subarid scrub to semi-tropical savanna and can be found throughout much of Africa south of the Sahara, including many of the surrounding islands. They often seek out refuge in cool dry areas. Mauritian tomb bats help control pest populations, including insects that carry human diseases. These bats tend to be nocturnal hunters and their normal prey consists of moths, butterflies, and termites. Not prone to large-scale roosting, T. mauritianus is most often spotted on the sides of buildings or on the trunks of trees in groups of around five individuals. They breed on average once or twice a year and rear usually one pup, though twins are occasionally reported. They usually deposit their hungry offspring in areas where they can feed voraciously, most often in berry bushes. This species is listed as least concern on the IUCN Red List due their wide distribution and stable population.
The diadem leaf-nosed bat or diadem roundleaf bat is one of the most widespread species of bat in the family Hipposideridae. It is probably most closely related to Hipposideros demissus from Makira and to Hipposideros inornatus from the Northern Territory in Australia. Hipposideros diadema is found in Australia, Indonesia, Malaysia, Myanmar, the Philippines, Thailand, and Vietnam.
The California leaf-nosed bat is a species of bat in the family Phyllostomidae. It is found in Mexico and the United States. Its natural habitat is hot deserts.
The Cape horseshoe bat is a species of bat in the family Rhinolophidae. It is endemic to South Africa, and is potentially threatened by habitat loss and disturbance of its roosting sites, although it is present in large enough numbers to be considered of least concern by the IUCN.
The long-fingered bat is a small carnivorous vesper bat.
