The Kashmir Gray Langur (Semnopithecus ajax) is an Old World monkey, one of the species of langurs. This, like other gray langurs, is a leaf-eating monkey. It is found in India west into Pakistani Kashmir[1] and Nepal[2] It was formerly considered a subspecies of Semnopithecus entellus and is one of several Semnopithecus species named after characters from The Iliad, along with Semnopithecus hector and Semnopithecus priam.[3]
The Kashmir Gray Langur is considered to be critically endangered. This is due to its restricted range, fragmented population, and threats from human agriculture and development activities.[2] It is arboreal and diurnal, and lives in several types of forest as well as in areas inhabited by humans at altitudes between 2200 and 4000 meters.[2]
The birthing season for the Kashmir Gray Langur runs from January through June, although almost half of all infants are born in March.[4] The infants are weaned at a higher age than most Asian colobines. While most Asian colobines wean their young within the first year, Kashmir Gray Langurs wean their young on average at 25 months.[4] This is apparently due to nutritional constraints, since monkeys in poorer sites wean their young at an older age.[4] The interbirth interval for females is about 2.4 years.[4]
Alloparental care occurs in Kashmir's gray langur for up to 5 months.[4] Males are usually protective of infants, but infanticide occasionally occurs.[4]
Although most Asian colobine groups contain only a single adult male and multiple females, multimale groups are known to occur within Semnopithecus species With Kashmir's Gray Langur, multimale groups may include as many as five adult males.[4] Females initiate copulation by soliciting a male, but not all solicitations result in copulation.[4]
