Pteropus scapulatus contributes to the pollination of plants that are important for humans, including trees used for lumber, food, and medicine.
Positive Impacts: pollinates crops
In regions of fruit production, this species is considered a pest because of its tendency to feed upon agricultural crops.
Negative Impacts: crop pest
Pteropus scapulatus is considered common, and is legally protected in Australia. This species does not qualify for endangered, threatened, or vulnerable status and is considered a taxon of least concern.
US Federal List: no special status
CITES: no special status
IUCN Red List of Threatened Species: least concern
Species within Pteropus are frugivores and do not echolocate. No information on the communication of P. scapulatus is available; however, generally Pteropus species are known to communicate with loud vocalizations. While roosting, vocalizations are emitted by adults and juveniles at frequencies that are audible to the human ear. Communication by such vocalizations occurs during agonistic behaviors, escaping agonistic behaviors, and by females when males attempt to copulate with them. Vocalizations by juveniles help mothers identify their young after foraging.
In addition to vocal communication, tactile communication is important between mates and between mothers and their offspring.
Chemical communication is important in some species of Pteropus, especially in helping males mark territories during breeding season. Although this behavior has not been reported for this species, it is possible that similar scent cues are used.
The role of visual signals, such as body postures, has not been investigated.

Little red flying foxes are important for the pollination and seed dispersal of native flora within Australia.
Ecosystem Impact: disperses seeds; pollinates
Little red flying foxes are known to primarily feed on blossoms of eucalyptus trees. However, it is currently uncertain what the importance of eucalyptus foliage is in their diet. It has been suggested that Pteropus species obtain high amounts of calcium from calcium-rich vegetation such as eucalyptus. There is some suggestion that P. scapulatus follows the foraging resources of eucalyptus blooms throughout the landscape. No other information pertaining to the foraging habits of little red flying foxes is currently available.
Plant Foods: fruit; nectar; flowers
Primary Diet: herbivore (Folivore , Frugivore )
Little red flying foxes (Pteropus scapulatus) are primarily found in Australia and have the largest distribution of any other member of the genus Pteropus within Australia. Occasionally, these bats have been seen as far away as Papua New Guinea. There has also been one sighting of an individual in New Zealand. Although little red flying foxes occur throughout Australia, they are particularly abundant in northern Australia.
Biogeographic Regions: australian (Native ); oceanic islands (Native )
Little red flying foxes occur throughout coastal regions as well as arid landscapes of inland Australia. Limited knowledge from recent studies suggests that these bats often congregate at camps in riparian habitat, such as fresh/saltwater mangroves, bamboo, and closed forests. Selection of such congregation sites may be determined by seasonal variation, as well as by other factors; such as human hunting, natural catastrophe regimes, and climatic fluctuations.
Habitat Regions: temperate ; tropical ; terrestrial
Terrestrial Biomes: forest
Wetlands: swamp
Other Habitat Features: agricultural ; riparian
No information is available on the life span of this species. However, other members of the genus are reported to have lived as long as 30 years in captivity. As flying mammals typically have lifespans longer than expected based solely upon their body size, it is likely that P. scapulatus has a similarly long lifespan.
Average lifespan
Status: captivity: 15.8 years.
Little red flying foxes are medium-sized bats. The average wingspan of P. scapulatus males varies from .9 to 1.2 m. Weights of these males can can reach 550 g. There is no relevant literature available pertaining to body length and basal metabolic rate of P. scapulatus. However the body length of black flying foxes (Pteropus alecto) is known to range from 240 to 260 mm.
After winter solstice, the testicular size and body weight of males increase.
Range mass: 550 g (high) g.
Range wingspan: 0.9 to 1.2 mm.
Average wingspan: 1.0 mm.
Sexual Dimorphism: male larger
Other Physical Features: endothermic ; bilateral symmetry
Average basal metabolic rate: 1.353 W.
Limited information is available on the predators of Pteropus species. In many states throughout Australia, P. scapulatus is considered a pest, and is subject to large-scale hunting and poisoning by humans.
Known Predators:
Females and males congregate in large camps, especially during the 2-month mating season and during the 5 months of lactation. As many as 1 million individuals are known to congregate at a single camp.
Studies suggest that most females are associated with males in harem groups during the mating season. After mating, females establish small groups consisting exclusively of females. These small female groups are maintained until young are born.
Mating System: polygynous
The breeding season of P. scapulatus occurs between the Australian spring months of November and December. It and appears to be regulated by circannual endogenous rhythms. Young are born 5 months later in April to May. Many species in the genus Pteropus undergo delayed implantation, so it is possible that the actual time of development is not as long as the gestation period indicates. Lactation in this genus lasts between 3 and 6 months, although data are not available on its duration for P. scapulatus. Sexual maturity is typically reached between 18 months and 2 years of age.
Breeding interval: These bats breed once yearly.
Breeding season: Breeding occurs in November and December.
Average number of offspring: 1.
Range gestation period: 4 to 5 months.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; delayed implantation
Average number of offspring: 1.
Average age at sexual or reproductive maturity (male)
Sex: male: 540 days.
Average age at sexual or reproductive maturity (female)
Sex: female: 540 days.
Young bats are not able to fly from birth, and so may be called altricial. In some Pteropus species, the mother carries her young with her for a few months. There are no data on this behavior P. scapulatus. Lactating Pteropus females raise their young close to adult size before they are weaned. Females must contribute close to all of the calcium that is required to the developing skeletal system of the offspring. As a consequence, females often suffer from osteoporosis. Females with osteoporosis have a greater chance of breaking bones necessary for flight. Without the ability to fly, there is a high probability that females with broken limbs will die from starvation.
There are no data available on the role of males in parental care.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female)

The little red flying-fox (Pteropus scapulatus) 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.
The first description was published by Wilhelm Peters in 1862, as a 'new species of flederhund from New Holland'.[2] The type specimen was collected at Cape York peninsula. The population gives its name to the 'scapulatus species group', as recognised by authors in the late twentieth century.[3]
Pteropus scapulatus is well known and referred to by many names, these include the 'collared' flying-fox or fruit-bat, the reddish fruit-bat and little reds.[4]
A flying mammal of the pteropodid family, frugivorous bats with simple dog-like heads, often found roosting closely together in large numbers. The characteristic absence of a tail distinguishes these 'flying-foxes' from other bats in Australia.[5] The wing is extended with a forearm measuring 120 to 150 millimetres in length, the head and body combined is 125 to 200 mm. The length from the tip to base of the ear is 29 to 40 mm, and these are quite prominent for an Australian 'flying-fox'.[6][5] A measured weight range of 300 to 600 grams, gives the species an average mass of 450 grams.[6]
The colour of the pelage is reddish brown, the short fur appearing over most of the body and more sparsely at the lower part of the leg. The fur at the head is a dark to light shade of grey. Creamy-white hair may appear at the shoulders, or a pale yellowish patch found between these.[6] The patagium of the wing is a pale brown colour, and somewhat translucent while the bat is in flight.[5][6]
Pteropus scapulatus emits an abrupt 'yap' sound, accompanied by a variety of screeches, squeals and twittering noises, voiced at a high-pitch. They resemble other species found in Australia, the bare legs, reddish fur colour, and the paler near-transparent wings distinguish it from the grey-headed species Pteropus poliocephalus, and the larger and black fruit-bat Pteropus alecto. Their appearance closely resembles Pteropus macrotis, which occurs at and north of Boigu Island.[6]
The largest range of all the species, extending further inland than the others of the family, Pteropus scapulatus will also decamp and roam widely to increase their food availability.[7][6] The primary source of food for this species is obtained from Eucalyptus and Corymbia blossoms. Their diet consists of nectar and pollen of these eucalypts and is responsible for the much of their pollination, the irregular flowering periods induce the camps to forage in new areas.[5] The nectar of Melaleuca species is also favoured, and they are attracted to other native and cultivated fruiting trees.[6] P. scapulatus camps may become large groups of tens of thousands, with records of some colonies of over one hundred thousand individuals.[4] This species gives birth 6 months later than the other mainland flying fox species, in April and May,[7] this may be to avoid exposing a newborn to the high temperatures of the northern austral summer.[5]
The populous and conspicuous camps of P. scapulatus attract a number of larger predators. including both terrestrial and aerial hunters. The sea eagle Haliaeetus leucogaster will capture these bats in flight as they leave their roosts. The snake species Morelia spilota is frequently found as a resident at these camps, lazily selecting an individual from the apparently unconcerned group at a branch. The bat is seized in the jaws and encircled by the python's body, then swallowed head first to be digested over the next week. The arid climate in parts of the range will prompt the species to seek water in the late afternoon, and this provides an opportunity for freshwater crocodile species Crocodylus johnstoni found across the Top End and northern parts of the continent.[5] A National Geographic Channel special program (World's Weirdest: Flying Foxes) documents that the little red flying fox will skim the surface of rivers, then lap the water from their fur; this can put them in within reach of the crocodiles snapping in the air.[8] The 'freshies', as these crocodilians are locally known, will also place themselves beneath the overhanging roosts of this species, and employ a strategy of thrashing at the shoreline to induce panic and aerial collisions. The species are quick and adept swimmers, presumably due to the advantages in surviving and escaping immersion in water.[5]
Larger camps are formed during the breeding period, around October to November, and reduce in size as the birthing period approaches, during March to April.[6] Females start to form separate maternity colonies as gestation advances, and they may join other Pteropus species at their roosts, the births occur in April to May after the dispersal of the larger camp. When the camp regroups later in the year the juveniles gather at their own roosts, joining the breeding camp at the next season when they have become sexually mature.[4]
The habitat of roost sites is often composed of wet understorey which provides a temperate microclimate. The 'little reds' will seek to roost closely with others, their combined weight may break branches as they join the camp at a tree. The species is susceptible to heat stroke, and many individuals die when suitable roost sites are unavailable. The disturbance to camps by human intervention during hot weather may cause the deaths of thousands of these bats.[5]
Pteropus scapulatus has a wide distribution range across the north and east of Australia, occupying coastal and sub-coastal regions. The western extent is restricted to coastal areas of northwest Australia, as far south as Shark Bay, and through the tropical and subtropical areas of the north and east to New South Wales and Victoria. The species is only occasionally found extending their range to the southeast of South Australia.[6] The appearance of P. scapulatus in New Zealand is regarded as accidental.[3] The range of the Australian pteropodid bats is bounded by areas of lower rainfall and more temperate climate, this species and the other flying-foxes are absent from the south and west of the continent.[5]
The camps of P. scapulatus are found close to streams, they leave these at night to forage in woodland and forests in temperate to tropical regions.[6]
A well known colony exists at the Mataranka Hot Springs, an attraction that has also been discouraged from inhabiting the site for the odour of their camps.[5] Colonies of P. scapulatus are recognised as important contributors to woodland ecology, acting as a major pollinator of trees that provide nectar at night. The eucalypts and other trees of riparian zones in the Murray Darling Basin will also be visited in productive seasons. During the austral summer, colonies join the diverse species of bats around the Brisbane cityscape to feed on the blossoms of the pink bloodwood Corymbia intermedia. Along the Brisbane River they share many roost sites with the grey-headed fruit-bat, P. poliocephalus, most notable of these is the Indooroopilly Island, known to be an old bat campsite, whose occupants are seen flying around the area after dusk. They also occupy a well established colony at Ipswich, Queensland, close to that state's capital.[5]
This species of flying fox hangs in a different way from other mainland species. The larger species tend to hang an arm's length apart, but the little reds tend to clump together so they may hang in groups of 20 or more animals on an individual branch. So, these animals are associated with significant canopy and branch damage in camps where they reside. They also tend to appear in very large numbers (20,000 or more) and the footprint of a camp can expand rapidly for the several weeks or months they remain at a site. Their large numbers and the damage they cause to a camp site mean they are not very popular animals.
The opportunity presented by cultivated fruit trees to wandering little reds may encourage them to return in large numbers if the regular foods are not available, resulting in damage to fruit and trees; for this reason they have been perceived as a pest species by orchardists.[4] Negative public perception of the species has intensified with the discovery of three recently emerged zoonotic viruses that are potentially fatal to humans: Hendra virus, Australian bat lyssavirus (ABLV), and Menangle virus.[9] There are few records of human fatality resulting from interaction with bats, limited to the rare and deadly incidence of ABLV, and their parasites find human hosts unsuitable.[5]
The animals are nomadic and difficult to track, as they tend not to live in urban areas. No accurate method in use currently can estimate the population to determine if it is stable or in decline. The species is very likely to be affected by the same factors that have seen the grey-headed flying fox and spectacled flying fox listed as threatened, that is, the destruction of foraging areas and roosting habitat.[10]
A new bridge built near Noosa Heads was skirted over by the species leaving a nearby roost, resulting in fatal collisions with motor vehicles travelling across it; a sign warning motorists at the Monks Bridge displays an image of the bat and has subsequently reduced the number of incidents.[5]

La piccola volpe volante rossa (Pteropus scapulatus Peters, 1862) è un pipistrello appartenente alla famiglia degli Pteropodidi, endemico dell'Australia.[1][2]
Pipistrello di medie dimensioni, con la lunghezza della testa e del corpo tra 197 e 227 mm, la lunghezza dell'avambraccio tra 131 e 145 mm, un peso fino a 447 g e un'apertura alare fino a 1,07 m.[3]
Il colore generale del corpo è marrone scuro, il collare varia dal bruno-rossastro al bruno-giallastro mentre la testa è densamente cosparsa di peli più chiari. I maschi hanno dei ciuffi di peli più brillanti intorno a delle ghiandole situate sui lati del collo. Il muso è lungo ed affusolato, gli occhi sono grandi e con l'iride marrone. Le orecchie sono lunghe ed appuntite. La tibia è priva di peli. Le membrane alari sono attaccate sul dorso nella regione lombare, ampiamente separate tra loro, sono bruno-rossastre e leggermente trasparenti. Gli artigli sono bruno-rossastri scuri. È privo di coda, mentre l'uropatagio è ridotto ad una sottile membrana lungo la parte interna degli arti inferiori. La dentatura è notevolmente ridotta.
Si aggrega in colonie numerosissime fino ad un milione di individui. Ha abitudini erratiche, spingendosi per diverse centinaia di miglia all'interno del continente australiano. È un importante impollinatore delle foreste native.
Si nutre principalmente di fiori delle specie di Eucalipto, e in maniera minore di frutti di specie di Ficus, Syzygium, Nauclea orientalis e Citrus.
Le femmine partoriscono in autunno, in contrapposizione alle altre specie di Pteropus australiane. Sono state osservate nascite anche a Gennaio e Febbraio, facendo ipotizzare un doppio ciclo riproduttivo annuale. I giovani sono indipendenti a 3 mesi dopo la nascita. Raggiungono la maturità sessuale a 18 mesi.[4]
Questa specie è diffusa in Australia: coste dell'Australia occidentale, Territorio del Nord, Queensland, Nuovo Galles del Sud e Victoria; Isola di Boigu e Thursday nello Stretto di Torres. Sono stati ritrovati crani appartenenti a questa specie a Mari, località della Papua Nuova Guinea centro meridionale.[1]
Vive in savane, mangrovie, foreste di papiri e bambù ed occasionalmente frutteti, fino a 300 metri di altitudine.
In accordo alla suddivisione del genere Pteropus effettuata da Andersen[5], P. scapulatus è stato inserito nello P. scapulatus species Group, insieme a P. woodfordi, P. gilliardorum e P. mahaganus. Tale appartenenza si basa sulle caratteristiche di non avere un ripiano basale nei premolari e di avere denti masticatori eccessivamente ridotti.
Altre specie simpatriche dello stesso genere: P. poliocephalus, P. conspicillatus e P. alecto.
La IUCN Red List, considerato il vasto areale e la popolazione numerosa, classifica P. scapulatus come specie a rischio minimo (LC).[1]
La piccola volpe volante rossa (Pteropus scapulatus Peters, 1862) è un pipistrello appartenente alla famiglia degli Pteropodidi, endemico dell'Australia.
Pteropus scapulatus is een vleermuis uit het geslacht Pteropus die voorkomt in het noorden en oosten van Australië, tot ver in de binnenlanden, en in het uiterste zuiden van Papoea-Nieuw-Guinea, ten zuiden van de Fly River.
P. scapulatus is een kleine vleerhond met onbehaarde onderbenen en doorzichtige vleugels. Het lichaam is roodbruin, soms met gele of witte vlekken op de schouders, de kop grijs. De kop-romplengte bedraagt 125 tot 200 mm, de voorarmlengte 120 tot 150 mm, de oorlengte 29 tot 40 mm en het gewicht 300 tot 600 g.
In het begin van de zomer (oktober-november) vormt dit dier grote koloniën van soms honderdduizenden individuen, waar ook paringen plaatsvinden. Niet lang nadat de kampen in maart of april uiteenvallen worden de jongen geboren, die na 18 maanden geslachtsrijp zijn. Deze soort eet voornamelijk nectar, maar ook fruit.

Довжина: 20 см. Розмах: 0,9–1,2 м. Вага 280—530 гр. Має явно червонуватий відтінок шерсті і є одним з найменших з видів Pteropus. Шерсть на голові часто сіра; шкірясті крила червонувато-коричневі й здаються напівпрозорими в польоті. Цей вид є ефективним дереволазом, використовуючи зчленовані пальці й ноги, щоб дертися з великою спритністю по гілках дерева.
Країни поширення: Австралія (по всій території, але особливо багато на півночі), Папуа Нова Гвінея (час від часу). Висота поширення варіюється від рівня моря до 300 м над рівнем моря. Цей вид зустрічається в склерофільних лісах, бамбукових, мангрових лісах, а іноді й у садах.
Сідала можуть містити понад один мільйон осіб. Це дуже кочовий вид. У своїх великих таборах, P. scapulatus ночують в безпосередній близькості й у щільних скупченнях, часто викликаючи обрив гілок дерев тропічного лісу під вагомого величезної кількості тварин на одній гілці. Вид в основному харчується нектаром і пилком евкаліптових квітів, хоча дієта також включає в себе квіти, фрукти, пагони, кору, сік і комах; іноді здійснює набіги в фруктові сади, коли їжі не вистачає, на превелике роздратування фермерів. P. scapulatus можуть літати більше 80 км на добу відвідуючи різні дерева і, використовувати їх чудовий зір і нюх, щоб знайти їжу.
Під час сезону розмноження в період з листопада по січень (австралійський кінець весни й початок літа) самці встановлюють територію в межах сідал, в яких вони активно відстоюють гарем від двох до п'яти самиць від інших самців. Після спаровування самиці утворюють невеликі групи, що складаються виключно з самиць, які підтримуються доти, поки не народжується молодь п'ять місяців по тому, в квітні-травні. Самиці народжують одне маля. Жінки несуть своє маля під час польоту протягом перших чотирьох-шести тижнів життя, після чого дитина залишається на сідалі, поки вони годуються в нічний час. Через два місяці, молодь буде рухатися і літати навколо між деревами в таборі. Статева зрілість зазвичай досягається у віці від 18 місяців до 2-х років.
Вид вразливий до втрати місць годування і ночівель через вирубку місцевої рослинності й для потреб сільського господарства і для міського розвитку. У багатьох штатах по всій Австралії P. scapulatus вважаються шкідниками фруктових садів, і в минулому були піддані великомасштабному полюванню і отруєнню. Додатковою загрозою є паркани з колючого дроту, бо на світанку крилани, що повертаються часто літають низько над землею, щоб зменшити опір вітру і багато з них не бачать паркани з колючим дротом, поки не буде занадто пізно.
Пропагується, щоб верхня ланка паркуну була замінена гладким, оцинкованим дротом як очевидне рішення проблеми. На щастя, цей крилан залишається поширеним у Австралії, де охороняється законом, і не вважається під загрозою.
