SALINA – Mango, a 26-year-old male Sumatran orangutan, recently relocated from the Metro Zoo in Miami to his new home at Rolling Hills Zoo. Born March 19, 1992, at the Oklahoma City Zoo, Mango had recently lost his mate at Metro Zoo and was being housed with the gibbons. It was on the recommendation of the Species Survival Program of the Association of Zoos & Aquariums that Mango become a companion to Rusa, a 38-year-old female orangutan at RHZ who lost her mate, Clyde, last year.
