Feeding behaviour of the Northern Plains Sacred Langur: LTUVWP [OLJ\Z LU [LSS\Z (Dufresne) was studied from September 2012 to (ugust 2013 in Jessore, Bangladesh. The study was based on direct observation from dawn to dusk and data was collected using focal animal sampling. The results showed that while they were largely folivorous, fruits and other items where actively sought out when available. We identified 54 plant species in the diet (33 trees, 8 shrubs and 13 herbs). Of the time spent feeding, the greatest amount was spent on leaves (57.5%) followed by fruits (20.7%), buds (8.5%), flowers (3.9%) and bark (0.5%). Langurs also consumed provisioned food (8.7%), and non plant food items including soil, water and fungi (1%). The number of different plant species consumed varied seasonally, being higher in winter (49 spp.) and summer (48 spp.) than in the rainy season (37 spp.). Time spent feeding on natural foods significantly differed between adult males and adult females while no difference between sub adult males and females was detected. The amount of time allocated to feeding was the highest in the early morning and the lowest at mid day, regardless of season. Time spent feeding did not significantly fluctuate seasonally.
