Stock Photo - The infants are just weeks old, with the eldest born just before Christmas on 20 December and the youngest born on 10 January. Primate keeper, Janet Lackey said: “It’s a very exciting time for the family group of 17 Squirrel Monkeys. We are starting to see the older babies venturing off mum’s back and exploring the trees and ropes, and being very playful together. The youngest baby is still clinging tightly to mum as there is quite a big developmental difference between four and six weeks of age. We do have a first time mum in the group, little four-year-old Yamma, and she is doing so impressively well. We are really proud of her,” Keepers are yet to name or determine the sexes of the babies, who are receiving lots of attention from the other adults in Taronga’s Squirrel Monkey group.""
