The Javan slow loris (N. javanicus) is native to the Indonesian island of Java, whereas the Bornean slow loris (N. menagensis) can be found on Borneo and nearby islands, including the Sulu Islands in the Philippines. Reproduction, physical growth and behavioral development in slow loris (Nycticebus coucang, Lorisidae). Lan DY. A slow loris has many ways to avoid getting attacked by a predator. Rasmussen DT. Social structure of the solitary slow loris Nycticebus coucang (Lorisidae). 1999. In fact, when kept together in captivity, they are quite sociable, although adult males can be very intolerant of one another and may fight, often resulting in serious injury (Ehrlich & Musicant 1977; Tenaza & Fitch 1984).

In one study, slow lorises (N. coucang) were predominantly solitary, spending only around 8% of their active period near other slow lorises. Information concerning distribution and habitat suitability for the Javan slow loris is currently very limited, both inside and outside conservation areas. Other reasons for habitat descrution include monoculture, logging, fuel-wood extraction, land use for paper production, and the construction of infrastructure (Choudhury 1992). Some of the size variation is clinal over the distribution of the genus, however N. bengalensis and N. pygmaeus are sympatric and N. pygmaeus is quite smaller than N. bengalensis (Ravosa 1998). 1991. Slow lorises do not emit alarm calls (Wiens & Zitzmann 2003b). Javan slow loris is an endangered primate that naturely inhabits in some agroforestry garden namely talun in West Java. Elliot O, Elliot M. 1967. In one anecdotal observation, several male slow lorises were seen to follow a female and attempt to mate with her (Elliot & Elliot 1967). Because their hind limbs and forelimbs are about
However, N. coucang do not show sexual dimorphism by weight (Kappeler 1991). These friendly relations define “spatial groups” which are a unit of social organization in the species. Wiens F, Zitzmann A. N. coucang also solicit copulation by walking in front of the male and urine-marking and vocalizing (Zimmermann 1989). Environmental niche modelling indicates that the Javan slow loris is more threatened by habitat loss than other slow loris species. Data collection was conducted during April-December 2008 in four villages in Tasikmalaya District and one village in Ciamis District. There is some evidence to suggest that N. pygmaeus may purposefully gouge trees to induce the flow of exudates for consumption (Tan & Drake 2001). Ultrasonic vocalizations out of the human hearing range, are emitted when slow lorises explore unknown environments and during handling (Zimmermann 1981). Observation carried out by observing the slow loris behavior every 5 minutes starting from the slow loris woke up to sleep. With the atrocities from the market still fresh on our minds, Carmen and I went to International Animal Rescue – Bogor, a site that primarily focuses on rescue, rehabilitation, and release of Javan and Sumatran slow lorises.

Choudhury AU. Generally, observations are held in 2 shifts from 17.00-05.00. Jhum cultivation (slash-and-burn cultivation) is also a significant habitat threat in India, as is tea cultivation and other agricultural land use (Choudhury 1992; Medhi et al. 1998). Cite this page as: Intl J Primatol 12(3):287-90. Further, recent wars in Indochina have significantly altered or destroyed slow loris habitats (Lan 1999). 2006). Am J Primatol 13(3):271-81. Grins are shown by infants, usually when stressed. Primates in northeast India: an overview of their distribution and conservation status. Civets and owls do not elicit a response from slow lorises nor do the predators react to their presence (Wiens & Zitzmann 1999). Behavior and ecology of wild slow lorises (Nycticebus coucang): social organization, infant care system, and diet. One example is the Critically Endangered Javan slow loris (Nycticebus javanicus), which finds itself increasingly restricted to montane regions with extreme climate patterns and habitat disturbance. 2007). The IUCN lists this species as Critically Endangered and declining. Appl Anim Ethol 9(3-4):317-30. Slow lorises in a rescue centre searching for a noisy (and very tasty) cicada.
