The big bonneted bat, or Dabbene's mastiff bat (Eumops dabbenei) is a species of bat in the family Molossidae, native to South America. It is named for a former conservator at the Buenos Aires National Museum. [2]
The big bonneted bat is a relatively large bat species, with adults measuring about 19 cm (7.5 in) in length, and weighing 100 g (3.5 oz). The tail is thick, and measures about 6 cm (2.4 in) in length. The fur is chestnut or pale grey, and lighter on the animal's underparts. The ears are broad and relatively short, and join together at their base in the centre of the forehead. Compared with other nearby species of bonneted bat, they have a larger body, a short, wide snout, short ears, and nostrils that do not form a tube. As in other bonneted bats, the males possess a gland on the throat that secretes a liquid that stains and mats the surrounding fur. [2]
Big bonneted bats are known from two distinct parts of South America. A northern population is known from Venezuela and Colombia, while a southern population has been identified in Bolivia, Paraguay, and northern Argentina. [1] One specimen was recorded in the south Pantanal wetland, southwestern Brazil. [3] There are no recognised subspecies. It is known to inhabit areas of low vegetation interspersed with patches of tropical forest, at elevations of up to 1,100 m (3,600 ft). [2]
Big bonneted bats are insectivorous, and roost in hollow trees and artificial structures such as houses. They have been reported to emit audible "piercing shrieks" when they are foraging for food. Little is known about their reproduction, although juveniles have been observed in December and January. [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 black bonneted bat, also known as Shaw's mastiff bat,, is a species of bat from the Americas.
The dwarf bonneted bat, or Peters' mastiff bat,, is a bat species from South and Central America.
Wagner's bonneted bat or Wagner's mastiff bat, is a species of bat in the family Molossidae. It is found in the Americas from Argentina and Peru north to Mexico, and Cuba. Populations in Florida in the United States are now recognized as the Florida bonneted bat
Sanborn's bonneted bat, is a bat species from South and Central America. It was first described from a specimen collected at Colonia Hansa, Brazil, and is sometimes also known as the Hansa bonneted bat.
The Colombian bonneted bat, also known as Trumbull's bonneted bat, is a bat species from South America. It is found in Bolivia, Brazil, Colombia, French Guiana, Guyana, Peru, Suriname and Venezuela.
The little white-shouldered bat is a species of bat from South and Central America. It is the only species within its genus, the name of which translates as "reaper" or "destroyer".
The Brazilian big-eyed bat is a species of phyllostomid bat from South America. The scientific name honours Italian naturalist Giacomo Doria.
The little big-eared bat is a bat species in the order Chiroptera and family Phyllostomidae. It is from South and Central America particularly Colombia, Venezuela, Guyana, French Guiana, Brazil, Peru, Ecuador, Bolivia, Argentina, Paraguay, Suriname and Trinidad. Though its exact population is unknown, it is considered widespread and occurs in protected areas, although its minor threats may be deforestation, but nonetheless is classified Least Concern. It is found in multistratal evergreen forests and dry thorn forests and forages near streams and is found hollow trees, logs, caverns, or houses with groups up to twelve. The head and body length measures at 43.8 mm for males and 44.6 for females and males usually weigh about 5 g while females weigh 5.7 g.
Eumops is a genus of bats in the family Molossidae. A total of 17 species of this genus have been described. The name "Eumops" comes from the Greek prefix "Eu-", meaning "good" or "true," and the Malayan word "mops," which means bat.
The western mastiff bat, also known as the western bonneted bat, the greater mastiff bat, or the greater bonneted bat, is a member of the free-tailed bat family, Molossidae. It is found in the Western United States, Mexico and South America. This species is the largest bat native to North America, and some of its distinguishing characteristics are its large ears, wings, and forearms. The subspecies Eumops perotis californicus is a species of concern as identified by the U.S. Fish and Wildlife Service. The range of this subspecies is principally southwest desert regions of the United States, along the border with Mexico; however, the range extends as far north on the Pacific coast as Alameda County, California.
The Guianan bonneted bat, or Thomas's mastiff bat, is a species of free-tailed bat from South America. It is poorly understood, because it is difficult to capture, and may be one of the rarest Neotropical bats.
The Cuban fig-eating bat, or white-shouldered bat, is a species of bat in the family Phyllostomidae, found only in the Caribbean. It is the sole extant species in the genus Phyllops, although two other species, P. vetus and P. silvai, are known from fossils.
The hairy yellow-shouldered bat is a species of bat in the family Phyllostomidae native to South America. There are no recognised subspecies.
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.
The Patagonian bonneted bat, also called the Patagonian dwarf bonneted bat, is a species of free-tailed bat found in Argentina, Bolivia and Paraguay.
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.
Eumops nanus is a species of bat found in Central and South America.
Eumops ferox, the fierce bonneted bat or the chestnut mastiff bat, is a species of free-tailed bat found in the Caribbean and Mexico. Until recently, it was synonymous with Wagner's bonneted bat.
Eumops wilsoni is a species of bat native to Ecuador and Peru. The bat has a distinct karyotype, sequence of the mitochondrial cytochrome-b gene, and other distinct genetic markers that distinguish it from closely related bats such as Eumops glaucinus and Eumops ferox. However, there are no morphological distinctions from those related species and thus there is uncertainty of its geographic distribution and population status, leading to its classification as "data deficient". Local threats to the bat's dry forest habitat further impede efforts to study the bats. Transition to farmland and urbanization threatens the dry forest habitat of the bat in the Andes. As an endemic species, the bat may be threatened by this habitat loss.
