@Summer Tanager Thanks. I add that both species are breeding in this exhibit. Once there were Guereza Colobuses too, but I don't know if those were breeding.
The breeding is a real surprise to me! I clearly don't know a lot about primates, and I assumed that the Patas Monkeys were a group of bachelor males! I love Patas Monkeys and would love to see more of them in a managed population.
