There are two new additions to the Capuchin monkey group in the Treetops exhibit, with both Possum and Cassie giving birth recently and increasing the size of the group to 13 members.
Both mothers are experienced, and the babies are doing well.
It's still too soon for their Keepers to be able to tell whether they are male or female, because they are clinging so tightly to their mothers.
Cassie's second baby was born on March 13th.
Possum gave birth to her 3rd baby on February 15th .
Damien is the father of both babies, and these births make him the father of eight.
Capuchins are found in South America, east of the Andes mountain range.
They are largely vegetarian, but they also eat insects and other invertebrates, such as snails and spiders, and nestling birds.
In the wild, they live in polygamous groups that generally number between three and 15 individuals.
Possum and Cassie arrived at Melbourne Zoo in 2008 from New Plymouth Zoo, in New Zealand, along with two other females.
Damien came from the Hamilton Zoo, also in New Zealand, at the same time.
