One of the most unique experiences at Parque Zoologico Caricuao were the monkeys. They don't live in cages in the zoo. They live in the trees and seem to have a grape addiction. They would come out and take food right out of our hands. In fact, some were well practiced at holding a grape or peanut in each hand and one in their mouth. They were fascinating to watch. One of the monkeys carried a baby around on her back and several hung upside-down by their tails to grab for food. I felt a little conspicuous carrying around the bag of grapes. It felt like a million eyes were on me, waiting to pounce.
