ST. LOUIS (KSDK) – The birth of a black and white colobus monkey at the St. Louis Zoo on Jan. 14 was a milestone in more ways than one.

That's because its 26-year-old mother was the oldest colobus monkey to ever give birth in any Association of Zoos and Aquariums zoo.

Mother Roberta has two other kids: 3-year-old Mosi and one and a half year old Pili. The newborn won't be named until its gender can be determined.

"Kivuli and Pili are very interested in the new infant," said Joe Knobbe, zoological manager of primates at the Saint Louis Zoo, in a news release. "Roberta allows them to look, but not get too close, even scolding them if they don't behave around the baby. For the youngsters, it's important that they learn from the adults how to properly care for and interact with infants."

You can see the entire family at the Primate House. Visitors can see the infant poking its head out.

The colobus monkey is a threatened species found throughout the forests of east and central Africa. Infants are born with all white hair and a pink face. Adults, by contrast, are primarily black, with white hair encircling their faces and half of their tails.
