Note that although the article claims the most common primate species in sanctuaries are chimpanzees, capuchins and squirrel monkeys, this is only true for NAPSA member sanctuaries. It is not true for all sanctuaries.
The article mentioned a new bill that was introduced last month by Indiana Representative Jackie Walorski that requires federal agencies to develop a policy permitting animals no longer needed in research to be retired to sanctuaries. So much has changed in the last ten years when it comes to primate research. I hope guaranteed retirement is also on the horizon.
