The Madagascan flying fox, Madagascar flying-fox, or Madagascar fruit bat (Pteropus rufus) is a species of megabat in the genus Pteropus . It is endemic to Madagascar. Its natural habitats are diverse, and include moist lowland forests, dry forests, succulent woodlands, and spiny thickets, and mangroves. It eats figs and other fruits, flowers, and leaves. It is threatened by habitat loss. [1]

Description

This is the largest bat in Madagascar, with a body length of 23.5–27 cm (9.1–10.5 in), a wingspan of 100–125 cm (39–49 in), and a body weight of 500–750 g (1.1-1.65 lb). [2] Madagascan flying fox species have a brown color and the area on their chest and shoulders have a golden to slightly dark brown color. Its wings have a grey to black color, and both male and female Madagascan flying foxes look alike in appearance, but it is noted that the male has a slightly larger head than the females. [3]

Ecology

The Madagascan flying fox roosts during the day in large trees in colonies of up to 1000 individuals although 400 is a more normal number. The bats are noisy and easily disturbed, and if roused, the whole colony may move off to an alternative roost site. Most roosts are in isolated trees in degraded areas.

The diet mainly consists of fruit juice which is squeezed from the fruit in the mouth. In the process many seeds are swallowed and dispersed to other areas as they pass through the animal's gut. Other tree products are also eaten, including leaves, flowers and nectar. It has been observed to visit the flowers of the kapok tree Ceiba pentandra and it is believed to pollinate this tree. [4]

Distribution

The Madagascan flying fox is one of the most common bat species on Madagascar and is found in all parts of the island except the central highland region, ranging from sea level to 1,200 meters elevation. [1]

Status

In its Red List of Threatened Species, the IUCN has classified this bat as "Vulnerable". Its numbers appear to be declining and the greatest threat it faces is being hunted for bushmeat. Under Madagascar law, hunting this species is only permitted between the months of May and August. It is targeted both at its roosting sites and at the trees where it feeds, and the harvesting in many areas is believed to be unsustainable. It is taken as a subsistence food and also commercially. Besides this, it is threatened by loss of habitat as woodland is converted to agricultural land. This bat is present in only a few protected areas and in these it should receive some protection from hunting. [1]

<span class="mw-page-title-main">Megabat</span> Family of 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.

<span class="mw-page-title-main">Giant golden-crowned flying fox</span> Large bat species

The giant golden-crowned flying fox, also known as the golden-capped fruit bat, is a species of megabat endemic to the Philippines. Since its description in 1831, three subspecies of the giant golden-crowned flying fox have been recognized, one of which is extinct. The extinct subspecies was formerly recognized as a full species, the Panay golden-crowned flying fox. Formerly, this species was placed in the genus Pteropus; while it is no longer within the genus, it has many physical similarities to Pteropus megabats. It is one of the largest bat species in the world, weighing up to 1.4 kg (3.1 lb)—only the Indian and great flying fox can weigh more. It has the longest documented forearm length of any bat species at 21 cm (8.3 in).

<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 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.

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.

<span class="mw-page-title-main">Great flying fox</span> 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.
