Habitat utilization and feeding biology of Himalayan Grey Langur (Semnopithecus entellus ajex) were studied from April, 2006 to April, 2007 in Machiara National Park, Azad Jammu and Kashmir, Pakistan. The results showed that in the winter season the most preferred habitat of the langurs was the moist temperate coniferous forests interspersed with deciduous trees, while in the summer season they preferred to migrate into the subalpine scrub forests at higher altitudes. Langurs were folivorous in feeding habit, recorded as consuming more than 49 plant species (27 in summer and 22 in winter) in the study area. The mature leaves (36.12%) were preferred over the young leaves (27.27%) while other food components comprised of fruits (17.00%), roots (9.45%), barks (6.69%), flowers (2.19%) and stems (1.28%) of various plant species.
2006年4月至2007年4月，在巴基斯坦阿扎德查谟和克什米尔的马基亚拉国家公园，对喜马拉雅灰叶猴（Semnopithecus entellus ajex）的栖息地利用和觅食生物学进行了研究。结果表明，在冬季，叶猴最喜欢的栖息地是散布着落叶树的湿润温带针叶林，而在夏季，它们更喜欢迁移到海拔较高的亚高山灌丛森林中。叶猴的食性为食叶性，在研究区域记录到它们食用超过49种植物（夏季27种，冬季22种）。成熟叶片（36.12%）比幼叶（27.27%）更受青睐，而其他食物成分包括各种植物的果实（17.00%）、根（9.45%）、树皮（6.69%）、花（2.19%）和茎（1.28%）。
