when you enter the zoo, don't miss them near the entrance, roam freely on their tree. i almost missed it but lucky i was with my friend who showed me that there is this cutie on the tree. there are many of them just chillin' on top of the tree or sometime they come down to lower part of the tree and that's when you grab your chance to take their photos. someone even put their phone very close to them and they didn't mind. but remember, no touching or feeding.
