Bolivian gray titi monkeys are generally monogamous and produce their offspring following a 132 day gestation. They’re unique in that a few days after birth the infants are primarily carried by their father and later by their siblings. Assistant Curator for Primates at Lincoln Park Zoo Maureen Leahy said, “We have already seen the new infant being carried by the father, Ocala, and two of the other siblings, Suriqui and Madeira.”

Titis do not have prehensile tails like some other South American monkeys. However, when any two or more members of a titi family group sit next to each other, they typically twine their tails together like a braid. This behavior is unique to titis and may serve to reinforce the pair bond and other social relationships within a group. Titis engage in this behavior both awake and asleep.

The infant’s parents were paired together here in 2001 and seven babies later are still going strong. The titi monkey family is on exhibit every other day in the Helen Brach Primate House.
