Thank you! Very interesting diet! It seems that not very special. Most of the food items are easy to acquire for a non-tropical zoo except the fresh leaves. I guess the leaves are the secret that Yokohama Zoo keeps the monkeys successfully In fact I am so surprised that there are so many fruits contained in the diet, as I used to think the proboscis monkey is a strictly leaf-specialist.
