In the 2007 Guide Book of San Diego Zoo there is a photo of Wolf's guenons interacting with red-flanked duikers. I've always thought that the guenons shared space only with pygmy hippos, and the monkeys were also found near the orang/siamang exhibit in a glass-fronted enclosure. Was there a 3rd location for Wolf's guenons that also contained the duikers or were the duikers in with the pygmy hippos as well? It is sometimes tough keeping track of the animal merry-go-round at this particular zoo!
