 Do you know the dark-eyed Himalayan gray langur is one of the least Steady species of langur. It is distributed in a varied habitat which includes dry savanna and tropical rainforest Now recently the scientists have made an effort to study about the diet habits of these species Do you know what they have found? That is what we are going to see in this video. Just wait to know more Langurs are an important species as they occupy a key position in the food chain of many forest ecosystems In India, most langurs come under the genus Semnopetakas Coming to the Himalayan gray langur its scientific name is Semnopetakas Ajax This Himalayan gray langur is a long-tailed monkey know that it is also known as cashmere gray langur These species can be easily identified by its large size and the silver dark-colored hair in the outer side of both the fore and Hyalurhams remember they incubate area between 2200 to 4000 meters above mean sea level in Subtropical forest then tropical moist temperate forest Alpine forest then coniferous and broad-leaved forest and they also found in scrublands In India earlier their distribution was reported from Himachal Pradesh and Jamun cashmere But now Himalayan gray langur or confined to the Shamba valley of the western Himalayas in Himachal Pradesh They are also reported to be found in Nepal and Pakistan now talking about their food habits They are basically Folivorous that is they are basically Leaf eaters, but they also feed on a combination of fruits leaves stem bags roots and flowers Sometimes they also observed feeding on insects the Himalayan gray langur is present in a particular area Only during some parts of the year they change their locality during different seasons depending upon the availability of food and Environmental conditions these langurs come to Agricultural fields during the harvesting of crops and move to the deep forest during the other periods of the year So in the recent past it had been recorded that the langurs usually raid the crops of local farmers This is mainly due to the destruction of langurs natural habitat and reduction in the natural food resources of this species in the Forest see the raiding of crops by langurs causes huge economic losses to farmers So our new kind of conflict has developed between the ecology of these animals and local farmers now talking about the threats to Himalayan gray langur the major threat is habitat loss That is the expansion of human population and developmental work leads to habitat loss Then the other threats include land degradation land fragmentation Overgracing forest fire deforestation and etc. Now talking about conservation status They are placed in the endangered category under the IUCN red list of endangered species Recently a study was conducted on diet composition of two groups of Himalayan gray langur This particular study was conducted in the area, which is in and around the Kalatop Khajiar wildlife sanctuary in Himachal Pradesh That is one group of langur is inhibiting the Kalatop forest at an average altitude of 2396 meters and the other group is based in the Khajiar forest at an average altitude of 2188 meters the study found that the Domains of the two groups were only 208 meters apart But the altitudinal gap made a huge difference on their diet the Kalatop group Satisfied their craving by feeding on flowers But the Khajiar group ate fruits for a change of taste and the study highlighted that the preference for fruit Or flowers is due to the difference in their distribution in terms of elevation and availability of a particular plant part I hope now you can understand how a single geographical factor could contribute to an adaptation So to know more concepts like these you can subscribe to Shankar IAS Academy YouTube channel now Thank you for listening
