The dwarf little fruit bat (Rhinophylla pumilio) is a species of leaf-nosed bat from South America. [2]
As its name implies, the dwarf little fruit bat is a relatively small bat. Adults are just 4 to 6 cm (1.6 to 2.4 in) in head-body length, and weigh only 7 to 14 g (0.25 to 0.49 oz). Females are slightly larger, on average, than males. The fur is generally drab, being brown or reddish-brown across the entire body, although the individual hairs have white roots. The ears are rounded and hairless, with a relatively small tragus, and are pinkish-brown in colour. The bats have a prominent nose-leaf, which, when flattened, easily extends to the animal's forehead. [3]
The wing membranes are blue, and contrast with the bony parts of the wing, which have a distinct white colour. They extend all the way to the base of the toes, and the uropatagium reaches to mid-way along the lower leg. There is no tail, a feature which distinguishes these bats from the otherwise similar short-tailed fruit bats that inhabit the same region. A further distinguishing feature is the shape of a series of protuberances found on the chin of both groups; in dwarf little fruit bats, the central bump is triangular, rather than circular, and is flanked by fleshy pads, rather than by a V-shaped pattern of smaller nodules. [3]
Dwarf little fruit bats are found in across much of northern South America east of the Andes, from northern Bolivia, through eastern Peru and Ecuador, across northeastern and Amazonian Brazil, and into southern Colombia and Venezuela, and throughout the Guianas. [1] They are widespread, and generally present in large numbers where they are found, preferring primary forest below 1,400 m (4,600 ft), but are also sometimes found in more disturbed habitats, including plantations and pastures, and in open savannah. [3] [4]
No subspecies are recognized.
Dwarf little fruit bats are exclusively herbivorous, eating a wide range of fruits, including Philodendron , matico, arum, and figs. They help to disperse the seeds of some these fruits, which pass unharmed through their digestive tracts, [3] and have also been observed to eat pollen from some plants. [5]
They are nocturnal, spending the day in tent-like roosts constructed from the leaves of Philodendron and similar plants, typically 1.5 to 15 m (4 ft 11 in to 49 ft 3 in) above the ground. The roosts are temporary, with the bats moving every few days, and are found in small groups, occupied by a single male and up to three females. The bats are most active immediately after dusk and before dawn, foraging in the mid-canopy and forest understory, and covering an area of 5 to 15 ha (12 to 37 acres) each night. Pregnant females have been captured at most times of the year, suggesting the bats have little, if any, defined breeding season. The female gives birth to a single young. [3]
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 spectral bat, also called the great 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 lesser long-nosed bat is a medium-sized bat found in Central and North America. It is sometimes known as Sanborn's long-nosed bat or the Mexican long-nosed bat, though the latter name is better avoided since it is also used for the entire genus Leptonycteris and for one of the other species in it, the greater long-nosed bat.
The Egyptian fruit bat or Egyptian rousette is a species of megabat that is found in Africa, the Middle East, the Mediterranean, and the Indian subcontinent. It is one of three Rousettus species with an African-Malagasy range, though the only species of its genus found on continental Africa. The common ancestor of the three species colonized the region in the late Pliocene or early Pleistocene. The species is traditionally divided into six subspecies. It is considered a medium-sized megabat, with adults weighing 80–170 g (2.8–6.0 oz) and possessing wingspans of approximately 60 cm (24 in). Individuals are dark brown or grayish brown, with their undersides paler than their backs.
The spotted-winged fruit bat, is the smallest megabat in the world, and the only species in the genus Balionycteris. It inhabits forests in Indonesia and Malaysia.
The Honduran white bat, also called the Caribbean white tent-making bat, is a species of bat in the family Phyllostomatidae. It is the only member of the genus Ectophylla. The genus and the species were both scientifically described for the first time in 1892. It has distinctive, entirely white fur, which is only found in six of the roughly 1,300 known species of bat. It constructs "tents" out of understory plant leaves by strategically cutting the leaf ribs with its teeth; it roosts in these tents during the day. It is a specialist frugivore, consuming almost exclusively the fruits of one species of fig. Females can likely become pregnant twice per year, giving birth to one offspring at a time.
The silver fruit-eating bat is a South American bat species of the family Phyllostomidae.
The yellow-throated big-eared bat or orange-throated bat(Lampronycteris brachyotis) is a species of bat from South and Central America, where it ranges from southern Mexico to Brazil. It is monotypic within the genus Lampronycteris. A frugivore and insectivore, it is found in lowland forest up to an elevation of 700 m. Its activity is greatest in the first two hours after sunset, and peaks again after midnight.
The dark long-tongued bat is a species of bat from South and Central America. It was formerly considered monotypic within the genus Lichonycteris, but is now recognized as one of two species in that genus, along with the pale brown long-nosed bat. It is small species of bat, with adults weighing 6–11 g (0.21–0.39 oz) and having a total length of 46–63 mm (1.8–2.5 in).
Tomes's sword-nosed bat, also known as the common sword-nosed bat is a bat species from South and Central America. It is also found in the Bahamas, as is known only from one specimen collected on the island of New Providence.
The white-throated round-eared bat is a South and Central American bat species found from Honduras to Bolivia, Paraguay and Brazil. It creates roosts inside the nests of the termite, Nasutitermes corniger. It thrives on a mainly insect-based diet, focusing on the surfaces of foliage to hunt, and also eats fruit and pollen. It has a very wide range and is a common species over much of that range, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The greater spear-nosed bat is a bat species of the family Phyllostomidae from South and Central America. It is one of the larger bats of this region and is omnivorous.
The eastern or Queensland tube-nosed bat is a megabat in the family Pteropodidae that lives in north-eastern Australia. N. robinsoni is one of the few species in Pteropodidae that roosts solitarily. They get their common name from their raised tubular nostrils which is unlike most other species in the family. They are a deep brown with gray heads and sparse yellow spotting.
The hammer-headed bat, also known as hammer-headed fruit bat and big-lipped bat, is a megabat widely distributed in West and Central Africa. It is the only member of the genus Hypsignathus, which is part of the tribe Epomophorini along with four other genera. It is the largest bat in continental Africa, with wingspans approaching 1 m (3.3 ft), and males almost twice as heavy as females. Males and females also greatly differ in appearance, making it the most sexually dimorphic bat species in the world. These differences include several adaptations that help males produce and amplify vocalizations: the males' larynges are about three times as large as those of females, and they have large resonating chambers on their faces. Females appear more like a typical megabat, with foxlike faces.
The Honduran fruit-eating bat is a species of bat in the family Phyllostomidae. It is found in El Salvador, Honduras, and Nicaragua.
The greater short-nosed fruit bat, or short-nosed Indian fruit bat, is a species of megabat in the family Pteropodidae found in South and Southeast Asia.
Wahlberg's epauletted fruit bat is a species of megabat in the family Pteropodidae. It is commonly found across southern Africa.
Rhinophylla is a genus of South American bats in the family Phyllostomidae containing these species:
Lamotte's roundleaf bat is a species of bat found only at Mount Nimba on the border of Côte d'Ivoire, Guinea and Liberia. It is critically endangered.
The lesser short-nosed fruit bat is a species of megabat within the family Pteropodidae. It is a small bat that lives in South Asia and Southeast Asia. It weighs between 21 and 32 grams, and/or 70 to 127 mm. It occurs in many types of habitat, but most frequently in disturbed forest, including lower montane forest and tropical lowland rain forest, plus gardens, mangroves, and vegetation on beaches.
