Distribution of the big-eared flying fox

The big-eared flying fox (Pteropus macrotis) is a species of bat in the family Pteropodidae, larger bats who subsist largely on fruits. The species is distributed across a range in Indonesia, Papua New Guinea and islands nearing the Cape York peninsula at the northeast of Australia, at elevations less than 500 metres and often in coastal mangroves.

Taxonomy and etymology

Pteropus macrotis was described as a new species in 1867 by German naturalist Wilhelm Peters. The holotype had been collected on the Indonesian island of Buru. [2] Its species name "macrotis" comes from Ancient Greek makrós meaning "long" and oûs meaning "ear". [3]

P. macrotis is also referred to by the common name large-eared flying-fox. [4]

Description

Distinguished in the region as a smaller species of the Pteropus genus, their forearm length ranges from 143 to 157 millimetres. [5] The pelage is uniformly dark brown, but for yellowish coloration at the mantle and highlights of the ventral fur. The ears of P. macrotis are distinctly elongated to a fine point, the length from notch to tip is 30 to 37 mm. A range in length of the head and body combined is recorded as 180 to 240 mm, their mass is from 315 to 425 grams. [4]

Biology and ecology

Its diet consists of plant matter such as fruit and flower blossoms, including the blossoms of coconut trees. [6] It has been known to be infected by the blood parasite Mycoplasma mariboi , a kind of Rickettsiales. [7]

Range and habitat

It is found on the island of New Guinea, appearing in both Indonesia and Papua New Guinea. It also occurs on the island of Salawati (Indonesia), Boigu (Australia), Saibai (Australia), and the Aru Islands (Indonesia). It is generally found at elevations below 500 m (1,600 ft) above sea level. It is associated with forested habitat, including tropical moist forest, dry forest, and monsoon forest. [1]

Megabat Family of relatively large flying mammals (fruit bats)

Megabats constitute the family Pteropodidae of the order Chiroptera (bats). They are also called fruit bats, Old World fruit bats, or—especially the genera Acerodon and Pteropus—flying foxes. They are the only member of the superfamily Pteropodoidea, which is one of two superfamilies in the suborder Yinpterochiroptera. Internal divisions of Pteropodidae have varied since subfamilies were first proposed in 1917. From three subfamilies in the 1917 classification, six are now recognized, along with various tribes. As of 2018, 197 species of megabat had been described.

<i>Pteropus</i> Genus of large bats

Pteropus is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in the South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. There are at least 60 extant species in the genus.

Little red flying fox Species of bat

The little red flying-fox is a megachiropteran bat native to northern and eastern Australia. The species weighs about half a kilogram, one US pound, and is the smallest species of Pteropus in mainland Australia. P. scapulatus occurs at the coast and further inland, camping and flying to the tropical to temperate regions that provide them with an annual source of nectar. They exhibit an unusual method of obtaining drinking water during dry periods, skimming a stream's surface to gather it onto their fur while they are in flight.

Long-tongued nectar bat Species of bat

The long-tongued nectar bat, also known as the northern blossom bat, honey nectar bat, least blossom-bat, dagger-toothed long-nosed fruit bat, and lesser long-tongued fruit bat, is a species of megabat. M. minimus is one of the smallest species in the family Pteropodidae, with an average length of 60–85 mm. It has a reddish-brown colouring with relatively long hair compared to the other species. The hair on the abdomen is a lighter colour, and a dark brown stripe runs bilaterally down the top of the head and back.

Spectacled flying fox Species of bat

The spectacled flying fox, also known as the spectacled fruit bat, is a megabat that lives in Australia's north-eastern regions of Queensland. It is also found in New Guinea and on the offshore islands including Woodlark Island, Alcester Island, Kiriwina, and Halmahera.

Black flying fox Species of mammal

The black flying fox or black fruit bat is a bat in the family Pteropodidae. It is among the largest bats in the world, but is considerably smaller than the largest species in its genus, Pteropus. The black flying fox is native to Australia, Papua New Guinea, and Indonesia. It is not a threatened species.

Small flying fox Species of bat

The small flying fox, island flying fox or variable flying fox is a species of flying fox in the family Pteropodidae. It is found in Australia, Cambodia, Indonesia, Malaysia, the Maldives, Myanmar, Papua New Guinea, the Philippines, the Solomon Islands, Thailand, and Vietnam.

Black-bearded flying fox Species of mammal

The black-bearded flying fox is an endangered species of megabat in the genus Pteropus. It is endemic to Indonesia, found on the islands of Ambon, Buru, Seram, Banda, and Yamdena. Currently considered monotypic, it formerly included the Aru flying fox and Kei flying fox as subspecies.

Black-eared flying fox Species of bat

The black-eared flying fox, species Pteropus melanotus, is a bat of the family Pteropodidae (megabats). Also known as Blyth's flying fox, it is found on the Andaman Islands and Nicobar Islands (India), and in Sumatra (Indonesia). A population on Christmas Island, which is critically endangered, has been placed as a subspecies of this population. The conservation and taxonomic status of that population was later re-established as a distinct species, the Christmas Island fruit-bat Pteropus natalis.

Great flying fox Species of mammal

The great flying fox, also known as the greater flying fox or Bismarck flying fox, is a species of megabat in the genus Pteropus, found throughout lowland areas of New Guinea and in the Bismarck Archipelago. Conflicting evidence suggests that its closest relative is either the spectacled flying fox or, jointly, the Pelew and insular flying foxes. Two subspecies are recognized. At up to 1.6 kg (3.5 lb) in weight, it is among the heaviest bats in the world and the largest bat in Melanesia. It is a gregarious animal which roosts with hundreds or thousands of individuals. In part due to its wide variation in color, it has many taxonomic synonyms, including Pteropus degener, Pteropus papuanus, and Pteropus sepikensis. It may forage during the day or night in search of fruit, including figs or fruits from the family Sapotaceae. It is considered a least-concern species by the IUCN, though its numbers have been negatively impacted by what appeared to be a disease, as well as by hunting for bushmeat that occurs across its range.

Insular flying fox Species of bat

The insular flying fox or Pacific flying fox is a species of flying fox in the family Pteropodidae. It is geographically widespread, the most widespread flying fox in the Pacific: it is found in American Samoa, the Cook Islands, Fiji, New Caledonia, Niue, Papua New Guinea, Samoa, the Solomon Islands, Tonga, and Vanuatu.

Large flying fox Species of fruit bat

The large flying fox, also known as the greater flying fox, Malayan flying fox, Malaysian flying fox, large fruit bat, kalang, or kalong, is a southeast Asian species of megabat in the family Pteropodidae. Despite its scientific name, it feeds exclusively on fruits, nectar, and flowers, like the other flying foxes of the genus Pteropus. It is noted for being one of the largest bats. As with nearly all other Old World fruit bats, it lacks the ability to echolocate but compensates for it with well-developed eyesight.

Pemba flying fox Species of bat

The Pemba flying fox is a species of flying fox in the family Pteropodidae. It is endemic to the island of Pemba on the coast of Tanzania.

Bougainville monkey-faced bat Species of mammal

The Bougainville monkey-faced bat or Bougainville flying monkey is a megabat endemic to Bougainville Island of Papua New Guinea and Choiseul Island of the Solomon Islands in Melanesia. It inhabits mature forests in upland areas, within the Autonomous Region of Bougainville and Bougouriba Province.

Aru flying fox Species of bat

The Aru flying fox is a Critically Endangered species of megabat found in the Aru Islands in Indonesia. It was described by Wilhelm Peters in 1867. It was formerly considered a subspecies of the black-bearded flying fox. The species is poorly known, and has not been encountered since the 19th century. It is classified as critically endangered by the IUCN and is listed on CITES appendix II.

Bismarck masked flying fox Species of bat

The Bismarck masked flying fox is a species of flying fox in the family Pteropodidae found in Papua New Guinea and named after the Bismarck Archipelago. It was once considered a subspecies of Pteropus temminckii before being reassessed in 2001. This species has two subspecies, P. c. capistratus and P. c. ennisae. The IUCN classified it as Near Threatened in 2009, noting that the rate of decline is almost high enough to reclassify the species as Vulnerable.

<i>Nyctimene</i> (genus) Genus of bats

Nyctimene is a genus of bats in the Pteropodidae family. Commonly known as tube-nosed fruit bats, they are found in the central Philippines, eastern Indonesia, Papua New Guinea and the north-east coast of Australia.
