By the Numbers - Bolivian Gray Titi Monkey

Baby Bolivian gray titi monkey Ocho perches on mom, Delasol, at the Helen Brach Primate House

Eight Offspring for a Primate Pair

Born 30 days ago, the newest resident of the Helen Brach Primate House now has a name: Ocho. The numerical nombre honors both the monkey’s home range and familial status. Wild Bolivian gray titi monkeys range from Brazil to Spanish-speaking Paraguay and Bolivia. And little Ocho is the eighth offspring for parents Delasol and Ocala.

Of the eight offspring, four currently live with their parents in the treetops of the Primate House. (The others have found homes in different zoos, where some have their own families.) They can often be seen twining their tails together at the top of the exhibit, a social display that scientists believe may help the animals bond.

While little Ocho (whose gender is still unknown) spent early days close to mom, it has now branched out to other family members, who cooperate in rearing offspring. The baby still doesn’t venture far from family, but it has been seen scrambling all over dad, treating the elder caregiver like a jungle gym. Its older brother and sisters have received the same bouncing treatment.

“Ocho still spends a lot of time snuggled up, but we’re starting to see some bursts of activity,” says Curator of Primates Maureen Leahy. Come by the Helen Brach Primate House to see for yourself!
