There is a cute new addition on display at the St. Louis Zoo's primate house.

Kivuli is a baby colobus monkey that was born on Halloween. Her name suits her well because it's Swahili for "ghost" or "shadow."

Colobus monkeys are born with white hair and a pink face, but become primarily black with white hair around their faces and tails by the time they are 6 months old.

Kivuli's parents are 13-year-old mother Cecilia and 6-year-old father Kima. This is the first baby Cecelia has ever had.

"Primates rely heavily on learning through experience," Joe Knobbe, St. Louis Zoo manager of primates, said. "Cecelia is being a great mother to her infant thanks to the wonderful example of parenting she's learned from Roberta."

The baby's birth is part of the Associate of Zoos and Aquariums' Colobus Species Survival Plan, which is a program to manage a genetically healthy population of black and white colobus monkeys in North American zoos, according to the zoo.

These endangered monkeys are native to the forests of east and central Africa.

Another baby female colobus monkey, Pili, seen in the video below, was born at the zoo June 30. Kivuli and Pili share the same father.
