Cook when first arriving was very afraid of people, to the point that when the caretakers would look at him he would scream. Probably thinking that we would hurt him like his previous handlers did. After intense socialization and trust exercises, Coki can now deal with people. He is still very uncomfortable but has definitely toughened up. He is a leader/apha of a group of 23 Monkeys. He is a great leader and is very defensive of his family members when the care takers approach them. This is great prospect for his realize into the wild!
