Species: Callicebus donacophilus
Titi monkeys are found in forests and swamps along the Amazon River basin in Brazil. They mainly stay in the lower tree canopy and rarely descend to the forest floor.
Both male and female titi monkeys weight around 1 kg and have chestnut brown and grey fur. They often return to the same tree to sleep and can live up to 20 years.
Titi monkeys mainly eat fruit, although they also eat insects, leaves and flowers.
The International Union for Conservation for Nature lists titi monkeys as a species of Least Concern.
