The monkeys are free to roam. There were many infants. This place has been operational for almost 20years. Yes, most of their natural habitats have been destroyed due to deforestation but if they do not feed these monkeys, they might go extinct. That’s the price we pay to become a developed country. If you prefer to see proboscis monkeys in their natural habitats, do a river cruise with sights of fireflies but don’t forget to bring binoculars to see the monkeys.
