[4] The ornate titi is present on the IUCN Red List of endangered species, being recognized as “Vulnerable”, and having a general decrease in population trends.

The ornate titi has a thick, dense, fluffy, coat, with white ears and forehead, and grey hands and feet.

The ornate titi tends to sleep in vine tangles located on small branches of trees, generally preferring to be at least 15 m (49 ft) off of the ground.

[6] 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 of the species has become severely fragmented, with the current approximate area of habituated land around 20,000 km a decline of 30% in the last 24 years, and has been listed as Vulnerable by the IUCN since 1994 and is listed on Appendix II of CITES.

[6] The ornate titi is diurnal, rising early in the morning and remaining awake and active until sunrise, however this depends on the season, due to the change in availability in food, particularly fruit, which tends to only appear in abundance in the warmer months.

Several species of raptor have been observed attacking a titi, including the Guianan crested eagle (Morphnus guianensis) and the ornate hawk-eagle (Spizaetus ornatus).
