Collared titi National Park and El Tuparro National Park and in the two biological preserves Nukak and Puinawai. Actually a clarification of the taxonomic status of many populations is needed to be able to monitor their conservation state. Collared titi The collared titi (Cheracebus torquatus) is a species or a closely related complex of species of titi, a type of New World monkey, from South America. At the end of the 1980s the genus "Callicebus" was revised from the Hershkovitz concept of three species to thirteen neotropical species, with the collared titi, "Callicebus torquatus", having four subspecies.

Ornate titi thickets, tangles, thorny underbrushes and wet or even waterlogged areas. The ornate titi tends to sleep in vine tangles located on small branches of trees, generally preferring to be at least off of the ground. Like other members of the moloch group, the ornate titi is considered tolerant of seasonal flooding and disturbances within its habitat, and is commonly found living in areas of forest disturbed by humans, in particular thriving on highly disturbed habitats. However, due to the continuous expanding of human settlements and therefore declination of both the size and quality of the ornate titi’s habitat, the presence
