|

Nepal Sacred Langurs have a birth season in late winter to early spring, allowing infants to grow sufficiently to survive their first winter in their montane habitats. Their independence is important for their mothers because they need to move long distances down slopes in the winter when it is snowing. Although Asian colobines, in general, wean their infants by the time they are one year old, Nepal Sacred Langurs have been found to have long interbirth intervals of c.25 months and generally wean their young only after becoming pregnant again; lactation may last ¢.26 months. Interbirth intervals are as short as 13 months if the previous infant dies. Mating increases in late spring (May). The menstrual cycle is not evident. Proceptive behavior by females is shown by presenting their anogenital region, with their tail lowered and simultaneously head-shaking. Copulation is always preceded by this behavior, but it does not always lead to mating. They mate throughout the year, and even pregnant females mate regularly, but sexual activity is highest in July-November, and the majority of conceptions (84%) occur in July-September. Females maintain a dominance hierarchy in the group, and the dominant male interrupts mating attempts by subordinate males.

Nepal Sacred Langurs are diurnal and mainly terrestrial. They prefer the upper forest canopy but also go to the ground to travel over rocks and through open areas close to forests. When fleeing, they prefer to move through trees rather than along the ground,as is typical of species in more open habitats. They sometimes sleep on semi-barren cliffs at elevations of ¢.300 m or higher, taking advantage of their security and the radiant heat that rocks hold and the earlier sunrise that they receive.

Nepal Sacred Langurs live in multimale-multifemale groups of 4-47 individuals, with 1-4 adult males and a male-to-female sex ratio of 1:1-5—1-7. The meansize of five groups studied in 1972-1974 was 12-3 individuals. The same groups, and a sixth included in 1978, averaged 10-5 (resulting from a group splitting rather than a drop in population size). They also

all-male groups of ten or more, and males are sometimessolitary. Larger groups may split into dispersed subgroups, foraging separately while maintaining contact through intermittent calling by adult males. Annual home ranges of these temperate forest langurs are very large, 1275-12,700 ha, because they seasonally move up and down mountains. In mixed groups, there is a dominance hierarchy, and the dominant male frequently gives a deep contact call ("wao” or “ua”), which even in the thick vegetation makes him the constant center of attention. Subordinate and subadult males usually travel on the periphery of the group. The Nepal Sacred Langur does not “whoop-call” in morning choruses as is typical of the species living on the plains further south (e.g. the Bengal Scared Langur, S.

). This may be because of the montane topography that renders such calling ineffective as a spacing mechanism. Female Bengal Sacred Langurs in conflict slap each other while sitting erect, face-to-face, but this has not been observed between female Nepal Sacred Langurs. Females have linear and stable dominance hierarchies, expressed by displacements. More dominant females maintain a better physical condition than lower ranking females. Infanticide following male takeovers has not been reported for Nepal Sacred Langurs, despite prolonged observations (32 months) in Junbesi-Ringmo between Kathmandu and the Nepal-Sikkim border.

CITES Appendix I. Classified as Least Concern on The [IUCN Red List (2008). The Nepal Sacred Langur is protected under Schedule I, Part I, Indian Wildlife (Protection) Act, 1972, amended up to 2002, and the National Parks and Wildlife Conservation Act of 1973 in Nepal (listed as a common animal in Nepal). It is known to occur in at least ten protected areas: Chail Wildlife Santuary, Changthang Wildlife Sanctuary, Dachigam National Park, Hemis National Park, Kanchanjunga National Park, and Karakorum Wildlife Sanctuary in India; Mount Everest Natural Reserve, Langtang National Park, and Makalu Barun National Park in Nepal; and Manshi Reserve Forest in Pakistan. Major threats to Nepal Sacred Langurs include habitat loss; habitat degradation due to loss offruiting trees; timber, firewood, and charcoal extraction; forestfires; and encroachment by people. They are hunted and sold as a dry-meat delicacy in Nepal and used in native traditional medicine in China.
