Unusual foraging behaviour of the Bengal Slow Loris Nycticebus bengalensis (Lacépède, 1800) (Mammalia: Primates: Lorisidae) in the Shan Highlands, Myanmar

In April 2022, in northern Shan State, Myanmar, a Bengal Slow Loris Nycticebus bengalensis, an Endangered species, was observed entering a house and feeding on two Eurasian Tree Sparrows Passer montanus. This observation provides new information about the diet of Nycticebus bengalensis and its habituation to a highly disturbed urban environment.

Trade in Bengal Slow Lorises in Mong La, Myanmar, on the China Border

Abstract: Despite being protected throughout their range, the illegal trade in slow lorises is a clear impediment to their conservation. Little is known about this trade from Myanmar. We report on three visits to the town of Mong La, Myanmar, on the border with China, where Bengal slow lorises Nycticebus bengalensis are traded illegally. Combined with survey data from other researchers, it is clear that slow lorises are ubiquitously present at Mong La's animal market. They are traded either as parts—carcasses, skins, and hands and feet (average of 26 items/survey)—or alive (average of 5 individuals/survey). Live animals typically arrive at the market in the morning; they are slaughtered, and the carcass at least is sold the same day. Estimating from live animals, our data suggest that over a thousand Bengal slow lorises may be traded annually from this one market alone. Trade in Mong La may be local or may be geared towards the Chinese market, and thus the trade in Mong La is not only contra to Myanmar's ...

Persistence and protection of the Vulnerable Bengal slow loris Nycticebus bengalensis in Assam and Arunachal Pradesh, north-east India

AbstractThe Bengal slow loris Nycticebus bengalensis is the only strepsirrhine primate in north-east India. It is categorized as Vulnerable on the IUCN Red List. The limited information on its status and ecology is the main hindrance to developing a conservation strategy for this species in India. Therefore during February 2009–May 2010 we surveyed the species in 16 protected areas in Assam and one protected area in Arunachal Pradesh. We used recce transects to estimate encounter rates for the species. A team of 3–4 conducted night-time surveys (18.00–03.00) on foot, covering 370 km over 99 full and 28 partial nights. We recorded lorises a total of 22 times in nine protected areas in Assam and three times in the protected area in Arunachal Pradesh. The mean distance of lorises from transects at the time of encounter was 15.04 m, at a mean height of 12.36 m above ground. The encounter rate was 0.06–0.2 lorises per km, which is relatively low compared to encounter rates for slow lorises elsewhere in their range but higher than recorded by other studies in north-east India. We found that despite hunting and habitat loss Bengal slow lorises still exist in Assam and Arunachal Pradesh, albeit patchily within a forest block. The protected area network in these states is important for their conservation.

Medicinal plant exudativory by the Bengal slow loris Nycticebus bengalensis

Slow lorises are members of a rare guild of obligate exudativores. Secondary meta - bolites in their diet have been implicated as contributing to the evolution of both their slow basal metabolism and their venom. No long-term study has yet examined the feeding ecology of the largest of the lorises, the Bengal slow loris Nycticebus bengalensis. We conducted an 18 mo study from June 2008 to December 2010 in Hollongapar Gibbon Wildlife Sanctuary, Assam, India, to investigate whether Bengal slow lorises prefer gum, and whether there is any evidence of second- ary metabolites in their diet. We detected the lorises along line transects using existing trails and followed each animal as long as possible, recording selected behaviours via focal instantaneous sampling. We recorded 629 feeding incidents during 270 night walks. We found that up to 80.9% of feeding bouts were of plant exudates, followed by bark, floral parts, insects, fruits, and tender (i.e. immature) leaves. Within the plant exudate category, 5 species were consumed in 71% of the total exudate feeding bouts: Terminalia chebula, Mesua ferrea, T. arjuna, Ficus hispida and Dil- lenia indica. These species all have high medicinal value and are commonly used by the local communities for traditional medicinal purposes. Absorption of secondary metabolites from these plants may explain unusual healing patterns observed in wild slow lorises, but lacking in lorises held in captivity. Their dietary affinity towards medicinal plants could explain patterns of use of slow lorises within the traditional medicine trade in the Indo-Chinese region.

A total of 27 individuals consisting of 21 males and 6 females were rescued from the study sites; 81% of these were adult and 19% sub-adult. Of the 27 individuals, 12 were rescued from private gardens. All rescued individuals were kept under observation in the Biological Park zoo situated within the sanctuary, where they received the necessary treatment, and were then released to the wild in the sanctuary. Various anthropogenic threats were recorded in the study; these included illegal logging, firewood collection, forest fires and habitat encroachment to enable the traditional practice of shifting cultivation, and infrastructural developmental activities. The present study highlights factors impeding the conservation of slow loris in and around the sanctuary.

Abundance of primates reveals Samkos Wildlife Sanctuary, Cardamom Mountains, Cambodia as a priority area for conservation

AbstractWe conducted a primate survey in Samkos Wildlife Sanctuary, western Cambodia, during the wet season in 2009. We visually confirmed the presence of five out of six primate species thought to occur in the area: Bengal slow loris Nycticebus bengalensis, Indochinese silvered langur Trachypithecus germaini, pileated gibbon Hylobates pileatus, pig-tailed macaque Macaca leonina and long-tailed macaque Macaca fascicularis. We did not find any sign of the stump-tailed macaque Macaca arctoides and suggest it is absent in Samkos Wildlife Sanctuary and possibly from the Cardamom Mountains. We provide the abundance measures for each primate species; the three most abundant species were Bengal slow loris, Indochinese silvered langur and pileated gibbon. We propose Samkos Wildlife Sanctuary as a priority for primate conservation in Cambodia.

Population Survey of the Bengal Slow Loris,Nycticebus bengalensis,in Meghalaya, Northeast India

The Bengal slow loris Nycticebus bengalensis is a nocturnal prosimian that inhabits the forests of northeastern India. As with many nocturnal prosimian species, little is known about its behavior or ecology; even less information is available on its distribution and population status in northeastern India. We conducted a survey of forest patches in the state of Meghalaya, in northeast India, in order to assess its distribution. A secondary aim of our study was to estimate the severity of threats that may affect the long-term survival of the slow loris in Meghalaya. We surveyed sixteen sites in six districts. Slow lorises were seen in only two sites; however, information obtained through secondary sources indicated that they were present in a number of other forest patches across the state. Many of the forests surveyed were severely affected by logging, poaching and forest fires; it is imperative that conservation measures, aimed at protecting existing forest patches, be implemented in order to ensure the long-term survival of the slow loris and other mammals in the state.
