Ornate titi Ornate titi The ornate titi ("Plecturocebus ornatus") is a species of titi and is the smallest member of the family Pitheciidae, which also includes uakaris and saki monkeys. As it is a member of this family, it is classified as a type of New World monkey. It is endemic to eastern Colombia, and the only member of the "Plecturocebus moloch" group to occur north of the Rios Amazonas/Solimes/Napo axis, living at least 350 km away from the closest other member, the white-tailed titi ("Plecturocebus discolor"), which lives in the south of Colombia. It was once classified as the same species
Collared titi is found west of the Río Purús to the Yavarí River. The collared titi is seen most frequently in well-developed, tall forest with a closed canopy, usually over terra firme, but not exclusively so. The species also enters extensive várzea forest, especially if the forest is tall and well-developed. Such várzea forest contrasts with the habitat needs of the coppery titi, which also uses várzea forest and more commonly so. But the coppery titi survives in low, vine-covered, "poor" forest where the collared titi is rarely found. It is also known from some gallery forest, north of the Vichada River,
