Kashmir Gray Langur

The Kashmir Gray Langur is a leaf-eating monkey and lives in several types of forests at altitudes between 2200 and 4000 meters. The Kashmir Gray Langur is considered to be endangered. This is due to its restricted range, fragmented population, and threats from human agriculture and development activities.

These langurs are largely gray with a black face and ears. There are significant variations in the size depending on the sex, with the male always larger than the female. The head-and-body length is from 51 to 79 cm (20 to 31 in). Their tails, at 69 to 102 cm (27 to 40 in) are always longer than their bodies.

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 Asian colobines. 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.

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 Gray Langur, multimale groups may include as many as five adult males. Females initiate copulation by soliciting a male, but not all solicitations result in copulation.
