Oscar was retired from research into the care of the Born Free USA Primate Sanctuary in May 2018. Oscar had never walked on grass or earth and was initially afraid to step out of his transport crate. However, within a few hours, he began to explore his new enclosure, which he shared with Creed, who arrived at the same time.

Oscar has formed a bond with Creed and they were spotted grooming each other only a few days after arriving at the Sanctuary – an important part of primate sociability.
