@Zoofan15 This was outside the shop in between the Asian Elephant and the Orangutan/Siamang exhibits. I saw quite a few of them throughout the day, including in the Lemur Walk Through and outside Hutan's enclosure.
@Zoofan15@NathanTheAsian There's a lot of these guys free roaming around the zoo. Although they usually like to hang out around the forested parts of the zoo (Gorilla Rainforest and TOTE).
