摘要：Eco-ethological aspects of the Golden Langur (Trachypithecus geei) were studied between May 2013 to April
2015 in three fragmented habitats of Western Assam. The months were grouped into two broad seasons (Wet –
May to October and Dry – November to April). Three troops in each three habitats were taken and each group
was followed for an average of 6-10 days per month for determining group-size and composition, age-sex relationship.
A total of 33 troops were sighted and troop size (number of individuals in the troop) was recorded during
the study period. Troop size varied from 3 to 25 individuals.
