Abstract: Study carried out on one group of Western hoolock gibbon (Hoolock hoolock) to find out the activity profiles in relation to time allotment in different activities and its seasonal variation. The study group was selected from a fragmented forest patch in the Rose Kandy Tea Estate (24042/14.84//N, 92042/0.04//E) of Barak valley, Southern Assam, India. The home range of the study group was about 55 hectare. The vegetation profile of the forest patch is semi ever green type. A total of 12277 scan samples were recorded during December, 2011 to November, 2012 covering all the four distinct seasons. Annual activity profile revealed that the gibbon group spent highest time in feeding (33.6%) followed by movement (24.3%), resting (22.1%), social activities (14.6%) and calling (5.5%). The study revealed distinct seasonal variation in different activities. A little variation was found in age- sex wise time allotments in different activities in different seasons in the group. The activity profiles of the study group have revealed that feeding is the most crucial factor responsible for the variation in the activity profiles.
