Diurnal and arboreal, titi monkeys prefer dense forests near water. They easily jump from branch to branch, earning them their German name, ‘jumping monkey’. They sleep at night, but also take a midday nap. Titi Monkeys are territorial monkeys.
They live in family groups which consist of parents and their offspring, about 3 to 7 other members. They defend their territory by shouting and chasing off intruders.
Titi Monkeys vocalise synchronously early in the morning, probably to announce their presence in their territory. Their grooming and communication is important for the co-operation of the group. Titi Monkeys can typically be seen in pairs sitting or sleeping.
The diet of the Titi Monkeys consists mainly of fruits, although they also eat leaves, insects, bird eggs and small vertebrates. Titi Monkeys are monogamous (having only one mating partner), mating for life.
