  • Mukesh Kumar Chalise


Little is known about the habits, ecology, and population size of Macaca assamensis in Nepal. Its status and distribution within the Makalu-Barun area are sketchy at best, though, they have been sighted. In this study, the important behavioral characterists of free ranging, non-provisioned and wild M. assamensis were documented as observed in Lakuwa forest of Makalu-Barun Conservation Area. The group-size, composition, age-sex ratio, time budget and habitat analysis of the area were determined. The question of crop raiding was dealt separately during the investigation of their general food habits. Four major behaviors were studied and find out that they spent 44% of time in foraging, 25% in walking or moving, 13% for grooming and 18% in sitting and resting. Due to habitat characteristics and seasonal influence monkeys seems to engaged more time in feeding.
