Six Bolivian squirrel monkey brothers are settling into their new home after the move from Wellington Zoo, New Zealand.

Aged between three and 11, the boys were put into their new enclosure on Wednesday, July 1 after 30 days in quarantine.

They are Jan, 11; Esperanza, four; Xavi, four; Amaro, three; Zafado, 3 and Inquieto, three.

Primate keeper William Paterson said all were settling in well.

“They went in and were calm, like they had been in there for 10 months,” Mr Paterson said.

“Usually, you would open up the pit pen, which you transport them in, and they would sprint out and run to all the corners and try to get away from you.

“These guys walked out very calmly, didn’t run and just checked it all out.”

Mr Paterson said the monkeys were “loving life” at Mogo.

“They are exploring all the new vines and logs,” he said.

“They have a strict hierarchy.

"There is a dominant one who is 11 years old and is the biggest of them.”

The squirrel monkeys can jump high and have a high-pitched call.

“They can hang off their hind legs like a bat and are super strong for their size,” Mr Paterson said.

“They can hold twice, sometimes three times their weight.”

The majority of the primate’s diet is fruit and insects.

“We do substitute with a little bit of vegetables in captivity,” Mr Paterson said.

“When you break down the makeup of wild fruit and compare it to the human fruit, the human stuff if really high in sugar.

“We give them a little bit of vegetables because they are close to the wild fruit they would get.”

Mr Paterson said there was a possibility that the group may be part of a breeding program at the zoo in the future.

“We are at the very early stages of having them at the moment but we will just have to wait to see what happens,” he said.

In the wild these monkeys would be found in Bolivia, Brazil and South America.

Their small, white faces and black muzzles make them an adorable creature to look at.
