Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".
The spectral bat, also called the great false vampire bat, great spectral bat, American false vampire bat or Linnaeus's false vampire bat, is a large, carnivorous leaf-nosed bat found in Mexico, Central America, and South America. It is the only member of the genus Vampyrum; its closest living relative is the big-eared woolly bat. It is the largest bat species in the New World, as well as the largest carnivorous bat: its wingspan is 0.7–1.0 m (2.3–3.3 ft). It has a robust skull and teeth, with which it delivers a powerful bite to kill its prey. Birds are frequent prey items, though it may also consume rodents, insects, and other bats.
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 mouse-eared bats or myotises are a diverse and widespread genus (Myotis) of bats within the family Vespertilionidae. The noun "myotis" itself is a Neo-Latin construction, from the Greek "muós and "oûs", literally translating to "mouse-eared".
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.
The least storm petrel is a small seabird of the storm petrel family Hydrobatidae. It is 13–15 cm in length, with a wingspan of 32 cm. It is the smallest member of the order Procellariiformes. It was formerly defined in the genus Oceanodroma before that genus was synonymized with Hydrobates.
The black myotis is a vesper bat species from South and Central America.
The southeastern myotis is a small bat found throughout the Gulf Coastal Plain and the Lower Mississippi Alluvial Plain of the southeastern United States.
Findley's myotis is a species of vesper bat. It is found only on the Tres Marías Islands off the west coast of Mexico.
The eastern small-footed bat is a species of vesper bat. It can be found in southern Ontario and Quebec in Canada and in mountainous portions of the eastern United States from New England to northern Georgia, and westward to northern Arkansas. It is among the smallest bats in eastern North America and is known for its small feet and black face-mask. Until recently, all North American small-footed Myotis were considered to be "Myotis leibii". The western population is now considered to be a separate species, Myotis ciliolabrum. The eastern small-footed bat is rare throughout its range, although the species may be locally abundant where suitable habitat exists. Studies suggest white-nose syndrome has caused declines in their populations. However, most occurrences of this species have only been counted within the past decade or two and are not revisited regularly, making their population status difficult to assess. Additionally, most bat populations in the eastern U.S. have been monitored using surveys conducted in caves and mines in the winter, but eastern small-footed bats hibernate in places that make them unlikely to be encountered during these surveys. Perhaps as a result, the numbers of eastern small-footed bats counted in winter tend to be low and they are relatively variable compared to other species of bats. Many biologists believe the species is stable, having declined little in recent times, but that it is vulnerable due to its relatively restricted geographic range and habitat needs.
The Yanbaru whiskered bat(Myotis yanbarensis) is a species of vesper bat in the genus Myotis.
The Yuma myotis is a species of vesper bat native to western North America.
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.
Macrotus is a genus of bats in the Neotropical family Phyllostomidae. It is the only member of the subfamily Macrotinae. This genus contains two species, Macrotus californicus commonly known as California leaf-nosed bat and Macrotus waterhousii commonly known as Mexican or Waterhouse's leaf-nosed bat. The range of this family includes the warmer parts of the southwestern United States, Mexico, Central and South America, and the Bahama Islands. Characteristic for the genus are large ears and the name giving triangular skin flap above the nose, the "leaf". The California Leaf-nosed Bat inhabits the arid deserts of the southwestern United States as far north as Nevada, south to Baja California and Sonora, Mexico. The California Leaf-nosed Bat is of medium size, with a total length between 9 and 11 cm Its most distinctive features are the large ears, connected across the forehead. The body is pale grayish brown dorsally with whitish under parts. The pelage (fur) on the body is silky, the hairs on the back about 8 mm, on the front about 6 mm long. The posterior base of the ears are covered with hair of a woolly texture while the interior surface and most of the anterior border shows scattered long hairs.
The Bonin flying fox, also known as Bonin fruit bat, is a species of flying fox in the family Pteropodidae. It is endemic to four islands of the Bonin Islands group, Japan. Its natural habitat is subtropical forests. It is threatened by habitat loss.
Myotinae is a subfamily of vesper bats. It contains three genera: Eudiscopus, Myotis, and Submyotodon. Before the description of Submyotodon and analysis of its phylogenetics, as well as a phylogenetic analysis of Eudiscopus, the only member of Myotinae was Myotis.
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.
Antrozoini is a tribe of bats in the subfamily Vespertilioninae of the family Vespertilionidae. It contains the pallid bat, Van Gelder's bat, the genus Rhogeessa, and the fossil Anzanycteris. All species in this tribe are found in the Americas.
There are eighteen indigenous species of bats in Canada, which are found in many parts of the country. They are insectivores, and are prey to falcons, hawks, owls, snakes, cats, and raccoons.
The Maluku myotis, also commonly known as the Arafura large-footed bat, is a species of mouse-eared bat. Native to Indonesia, and possibly New Guinea and northern Australia, it one of several species known as "fishing bats" because they catch their prey on the surface of water, scooping it up with their large feet.
