Arboreal Locomotion

Dusky Langurs love to dwell upon higher canopies of trees in the forest. They prefer staying up there and moving around running, climbing and leaping on branches of trees.

Data source: Yap et al., 2019

The behaviour code:
a) Locomotion: (hind-limb dominated)
Quadrupedalism โ€“ Climbing, Leaping, Running, Walking
b) Positioning: Lying, Sitting, Standing

Family Matters

An average of 5-20 members in a group, consisting of 1 alpha male, 1-2 sub-adult male(s), multiple females, subadult females, juveniles, and infants. Both males and females disperse when they are about 3-4 years old.ย ย 

When it comes to observing the family behaviour, different kinds of interactions can be observed when they are active. Apart from feeding and moving around, they would take turns to groom each other too. There are several interesting human-like behaviour, such as embracing, chasing, and kissing.
