Titi monkey adenovirus Titi monkey adenovirus Titi monkey adenovirus (TMAdV) is an adenovirus first identified in a New World titi monkey of the genus "Callicebus", and the virus also infected to at least two humans. It is a large DNA-based virus which can cause death in monkeys, and respiratory illness has been recorded in humans. It was first discovered in Davis, California, at the California National Primate Research Center. The discovery of TMAdV was made by the laboratory of Charles Chiu and the UCSF-Abbott Viral Diagnostics and Discovery Center, using a DNA microarray test called the ViroChip that is able to detect all
Ornate titi daily activity lasts for around 11.5 hours, with feeding taking up around 2.7 hours. Their day is typically split into two feeding sessions, one in the morning and one in the evening, with a resting session at around midday. The last few hours of the day are generally spent feeding on leaves. The predominant and most important predators of all titis are raptors. Several species of raptor have been observed attacking a titi, including the Guianan crested eagle ("Morphnus guianensis") and the Ornate hawk-eagle ("Spizaetus ornatus"). Tufted capuchins ("Cebus apella") have also been observed killing and consuming an ornate titi.
