Abstract
Group size and group composition of Nilgiri langur (Trachypithecus johnii) was studied in two habitats of Parambikulam Tiger Reserve, Kerala, India. Group size and age-sex composition data was collected during scan sampling, 18 monitoring transect lines, road-strip count, and direct encounter of the groups. Mean group size value significantly differ between moist deciduous forest and evergreen forest. Group size was varied from 2 to 22. The maximum group size, 22 was recorded in evergreen forest habitat. The mean group size of Nilgiri langur is less in moist deciduous forest and higher in evergreen forest.
