Chicago’s Lincoln Park Zoo welcomed a baby Bolivian gray titi monkey April 9. Bolivian gray titi monkeys (also called white-eared titi monkeys) in the wild live only in tropical forests in central Bolivia.

The tiny monkeys weigh only about 2 to 3 pounds when fully grown. They’re generally monogamous and are known for their tendency to twine their tails together, resembling a braid, when sitting or sleeping in pairs.

Bolivian gray titi monkey fathers usually take over most of the baby-carrying duties when the young monkeys are just a few days old; siblings also participate in the care of younger monkeys in the family unit. The Lincoln Park Zoo’s newest addition has six older siblings, so it’s in good hands!
