The Zoo houses six white-cheeked gibbons and two siamangs at Gibbon Ridge, all of which rotate through the outdoor and indoor enclosures daily, allowing two groups to have outdoor access daily.
The viewing deck at Gibbon Ridge is the roof of a building, located next to the great meadow. Underneath visitors’ feet are tall holding enclosures fitted with platforms, cables, and swings with outdoor access and/or windows.

Zoo Diet
Each group is fed once a day: a mixture of kale, cabbage, green beans, carrots, apples, bananas, oranges, sweet potatoes, primate chow, a veg du jour (onions, broccoli, turnips, white potatoes, coconut, squash, cucumbers), and fruits such as mango, pineapple, kiwi, papaya, and melon. Amounts depend on the make up and ages of each group. Each animal receives one cooked egg per week.
Health Care
Each animal has a regular physical, including a dental check-up.
Fecal samples are checked twice a year to make sure that the
animals don't have any parasites.
Zoo Habitat
The tall outside enclosures of Gibbon Ridge allow visitors
to observe the gibbons’ advanced arboreal adaptations.
