Himalayan populations experience strong seasonality in their habitat between cold winters hanumam can fall as low as Average rainfall is Gray langurs are mostly vegetarian but are not exclusively leaf-eating like some colobines Vogel Over their distribution, gray langurs have variable diets by location, habitat type, as well as season and receive differing levels of provisioning by humans.
Trees and shrubs predominate, followed by herbs and grasses and finally other plant types reviewed in Vogel However, most water is attained from the food they ingest Starin Rarely, resins are eaten Newton Bark is eaten mostly in times of food scarcity and rarely at other times Sharma Gray langur diets change seasonally as well with shifts in food abundance. This is the case with the population probably S.
At this highly seasonal location, low-abundance winter December-March foods include leaf buds, ripe fruit, and the fallback food of evergreen mature leaves. During spring April-May food includes largely deciduous young leaves and bark. Summer monsoon foods June-September include deciduous mature leaves and fruits.
