(Nowak, 1999), Slender lorises are nocturnal and arboreal. After four weeks, young are placed in a sheltered location during active nighttime periods. uses smells or other chemicals to communicate, to jointly display, usually with sounds in a highly coordinated fashion, at the same time as one other individual of the same species, often a mate. The fur of the lower back may be slightly frosted, but less so than Loris tardigradus grandis. found in the oriental region of the world. We have come across so many people who do not even know the existence of a slender loris, and then we have those who traffic them, abuse them for black magic,” said Colonel Navaz Shariff, Chief Veterinarian and General Manager of PfA Wildlife Rescue & Conservation Centre, Bengaluru.

Slender loris of the Horton Plains, Ceylon Mountain slender loris. communicates by producing scents from special gland(s) and placing them on a surface whether others can smell or taste them, reproduction that includes combining the genetic contribution of two individuals, a male and a female. (Nekaris, 2003; Nekaris, et al., 2007; Schulze and Meier, 1995b), Like many mammals and most nocturnal primates, slender lorises make extensive use of scent markings to communicate information. “The only way to save them from extinction is through habitat conservation and awareness creation. “Lorises are elusive creatures and people’s memories can be dodgy with dates,” said Kulkarni. Both species are reported to form social associations in which the larger home ranges of one or more males overlap the smaller range of a single female. At least 4-5 individuals of the beady-eyed, small, elusive primate have been spotted in the park’s canopies. 1995. Predator defense by slender lorises and pottos.

Primates, 39/1: 13-27. The shrubs and trees that lined the Rajakaluves (Storm Water Drains) provided a corridor for lorises to travel to the Indian Institute of Science Campus, about 11 km in the west, or to the verdant green campus of University of Agricultural Sciences’ GKVK campus â 13 km to the North. After four weeks, lorises "park" their young in dense tangles of branches during nighttime foraging activity. Sometimes male-female duets are performed using krik calls. Folia Primatologica, 44/3-4: 216-226. Read more: Hunted and traded for body parts, the Bengal slow loris needs a conservation strategy. The woodlands in Hennur provided a sanctuary.

Loris tardigradus females and their infants react with alarm to the presence of venomous common kraits and moved to a sheltered location until the snake has passed. Loris tardigradus grandis is larger than L. t. tardigradus, has a less delicate appearance, and is more heavily furred, especially on the limbs. New York: Plenum Press. Apart from creating mini forests, we need to have canopy connectivity. Nekaris (2003) observed several wild male L. lydekkerianus rotating among three estrus females, with each male separately grooming each female at different times over the course of a single night. Evidence suggests that volatile chemicals ingested with insect food might be reused by lorises as a kind of olfactory camouflage. Multiple roads are slated to be widened at the cost of trees; while canopy cover in residential areas and research institutions have been on a decline.

Lorises have been sighted all across Bengaluru, even in the congested heart of the city, till a few decades ago. As in other strepsirhine primates, there is a toilet-claw on the second digit of both feet. If you could save lorises, you could save green spaces, mitigate urban heat effect, create a healthy ecosystem for other primates and birds,” she said. Diet and feeding behavior of Mysore slender lorises. No studies have investigated the composition or function of brachial gland exudate in slender lorises, but L. tardigradus may be protected from predation by virtue of unpalatability. ULSP’s surveys within the campus have indicated that lorises tend to favour native trees, which attract more insect populations than non-native species such as acacia, copper pod or gulmohar.
