[59] They use squeaks and shrieks to communicate stress. In the following months, the infants are capable of quadrupedal locomotion and can walk, run and jump by the second and third months.

Snub-nosed monkeys spend the majority of their life in the trees. They live together in very large groups of up to 600 members, splitting up into smaller groups in times of food-scarcity, such as in the winter. Groups consist of many more males than females. They have territorial instincts, defending their territory mostly with shouts.
