The San Francisco Zoo had the golden snub-nosed monkeys on exhibit in 1985 and the San Diego Zoo had them for several years in the 1980s (not sure when they left, but I saw them in 1988 and they had been there for a few years already). The Los Angeles Zoo was supposed to get them in 2009 and have them now. An exhibit was built and the loan fell through supposedly due to political problems between the U.S. and Chinese government over totally unrelated political issues. I am not aware of any golden snub-nosed monkeys in North America at this time and given LA Zoo's experience, I would be surprised if there are any in the foreseeable future (this is all speculation on my part).
