The new arrival, which has yet to be named, was born to first-time mother Margarita on December 21.

It’s the second spider money to be born at the zoo in recent times after Isadora was born in October.

Isodora was the first spider monkey to be born at the zoo in 16 years. In 2014 breeding male Pedro arrived from France.

Keeper Mel Friedman said Pedro was a highly valuable spider monkey in Australia and New Zealand due to his genetics.

It was fantastic to have two babies born in a three-month period, Ms Friedman said.

“[Margarita] has been proving her skills as an excellent mother, and has been taking great care of the baby, who clings to her belly as Margarita swings around her island home,” she said.

“Margarita is quite a private individual compared to Jai (Isadora’s mother), who is more social, but now and then she allows her Keepers to see the baby up close, which is very special.”

Once the baby becomes more active later in the year, Keepers expect to see her interacting with Jai’s four-month-old baby, Isadora. Isadora is already starting to engage with the rest of the troop while riding on her mother’s back.
