The Grizzly sisters and Dodge usually spend their time bts indoors. The devils have 5 exhibits, with 3 pairs. 2 pairs are in the new exhibit (4 separate spaces) and the original pair is along Tembo Trail across from the indoor hippo viewing. Was it you saw those primate species or those were signed? The zoo has 3 signage points, having those species rotating, along with Francois Langurs, Chinese Red Pandas and White-Cheeked Gibbons. ProMedica's Tropics room closes early upstairs. The tropics room holds dart frogs, geckos, victoria crowned pigeons and a few other tropical pigeons. It also formerly held blue morphos, and hummingbirds.
