The baby was born on 6th March to 11-year-old mum, Jimma and 14-year-old dad Ebano and is the attractions sixth youngster.
Senior Keeper Jodie Dryden said: “This is Jimma’s second baby so she’s already an experienced mum and the newborn looks to be thriving.
“She’s keeping a very tight hold of it at the moment so we haven’t had an opportunity to spot its sex, but as soon as we find out we’ll let you know!”
The troop, who are part of a European Endangered Species Programme, have been successfully breeding since 2014 and Dudley Zoo currently have four juvenile boys – Billie, Ambo, Gimbi and Dendi as well as Kadida - the only girl. Jimma is joined by fellow adult females Tana and Addis, who also both have two offspring each.
Gestation is usually around six months and mothers will carry the baby on their stomach for the first few weeks, before transferring it to their back.
The youngster will begin to gain more independence around five-months-old.
