Other than White-collared and Cherry-capped, do other posters think there's much realistic chance of mangabeys being on exhibit in Europe in 15-20 years' time?
Probably not- though the two species you mention have had something of a resurgence in the UK in recent years. I think Mangabeys are great monkeys- big, active, showy, colourful, what more could you want for a Primate exhibit? IMO London's Mangabey group is by far the best exhibit in that area of their Primates.
