Biology

Very little is known of the biology of the Nilgiri langur. Young are born mainly in May and November, after the monsoons that bring fresh leaf growth. This langur species form groups with one male and up to 23 females and young, who move through the forest eating the leaves of 102 plant species as well as some of their fruit, flowers and seeds. As sub-adults, males begin to fight for access to females, but are then displaced by the dominant male and forced to migrate in all-male groups (3).
