It is arboreal and diurnal, and lives in temperate and alpine forests.[1] It lives at the highest elevation of any non-human primate in the world and is found in forests at elevations ranging from 1,500 to 4,733 m (4,921 to 15,528 ft).[1][5]
The birthing season for the Kashmir gray langur runs from January through June, although almost half of all infants are born in March. The infants are weaned at a higher age than most Asiancolobines. While most Asian colobines wean their young within the first year, Kashmir gray langurs wean their young on average at 25 months. This is apparently due to nutritional constraints, since monkeys in poorer sites wean their young at an older age. The interbirth interval for females is about 2.4 years. Alloparental care occurs in Kashmir gray langur for up to 5 months. Males are usually protective of infants, but infanticide occasionally occurs.[6]
Although most Asian colobine groups comprise only a single adult male and multiple females, multimale groups are known to occur within Semnopithecus species. In Kashmir gray langurs, multimale groups may include as many as five adult males. Females initiate copulation by soliciting a male, but not all solicitations result in copulation.[6]
