Rio Mayo Titi Distribution

Rio Mayo Titi Characteristics

The Río Mayo titi[1] (Plecturocebus oenanthe), also known as the San Martín titi, is native to the San Martín region of Peru and is considered Peru’s most endangered primate.

  • They live in low-lying secondary forests and are often seen in bamboo groves, fruit clusters, grape vines, and palm-dominated forests.
  • At first glance, Río Mayo titi appears to have round, robust bodies. This is because their dense fur obscures their actual body shape and sometimes makes them look like growth on a branch – great for hiding from predators!
  • They use a long, intangible tail to balance themselves on branches.
  • They also have a variety of color types: individuals in the northern part of their range are more likely to have brown bodies with a white mask, while those in the south are more likely to have orange to dark brown bodies and no mask.
  • Sometimes pairs of different colors have common offspring.

Rio Mayo Titi Facts

  • Río Mayo titis are diurnal, like most New World Monkeys. They wake up with the sun and stay active until sunset.
  • They have two main feeding periods throughout the day with a break in between and spend most of their waking hours eating.
  • They are arboreal and quadrupedal and generally move with short hops. They are rarely seen on the forest floor.
  • Río Mayo titis have been described as somewhat temperamental and hesitant and don’t tend to be inquisitive.
  • Babies are born a uniform agouti color and begin to develop their white mask, if they have one, at around 5 weeks.
