The babies are two months old.

They can often be seen jumping from one climbing structure to another or playing in the trees on their island home at Dubbo zoo.

"The babies are starting to eat branches and leaves as well as trying vegetable pieces more and more now. They are still suckling from their mums which is to be expected as most of their nutrition is coming from their mother's milk," primate keeper Sasha Brook said.

In the coming months the lemurs will not only get better at climbing, they'll start to work out their hierarchy.

"For ring-tailed lemurs it is the females that are in charge of the group, so some of the male babies are still yet to work this out," Ms Brook said.

The best time to see the young lemurs is in the morning when the zoo opens. It's when the lemurs are fed so they're usually very active.

The babies will hopefully be named by the keepers in the coming weeks.
