Miller's mastiff bat (Molossus pretiosus) is a species of bat in the family Molossidae. It is found in Brazil, Colombia, Costa Rica, Guyana, Mexico, Nicaragua, and Venezuela. [1]

Contents

Distribution

Miller’s mastiff bat has a limited distribution and tends to inhabit isolated regions. This particular species of mastiff bat is native to Brazil, Colombia, Costa Rica, Mexico, Nicaragua, and Venezuela. Its main habitat is lowlands. [2]

Morphology

Miller’s mastiff bats have a powerfully built body, with a broad body frame and narrow wings. They have a thick mandible in comparison to other mastiff bats. They have a distinctive cusp shaped pattern on their molars and lack their third premolar. [3] Males tend to be larger than females. Full grown, an adult mastiff bat ranges from about 20 to 28 grams. [4] At birth, Miller’s mastiff bat is only about one-quarter its adult weight. [5] Miller’s mastiff bat had a variable fur coat color; ranging from black to a reddish color. The mastiff bat’s chest is speckled with white fur, and has black ears. [6] [7]

Behavior

Miller’s mastiff bat lives in open areas, mainly in grassland habitats. They have also been observed to build their roosts in caves, dry woodlands, roof dwellings, and thorn scrub. [8] They tend to live in areas by a river, lake, or watering hole. Water is important for drinking and foraging behaviors. [9] They are nocturnal, and start to become active at dusk, which coincides with the time when their food source becomes active. They tend to fly in a single file line to their destination. Their main food source are insects, such as beetles and moths. [10]

Conservation

Miller's mastiff bat is listed as a Least Concern species with a low risk of becoming extinct. This is due to its ability to adapt to changing habitats and the distribution of habitats it occupies. It is also located in a number of protected areas. There are no known threats to Miller's mastiff bat. [1]

<span class="mw-page-title-main">Free-tailed bat</span> Family of bats

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.

<span class="mw-page-title-main">Dwarf dog-faced bat</span> Species of bat

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.
