Every one is different but, if you have patience, always be calm around it and try feeding the first feeder or two by hand every day it may start to trust. If you don't succeed at first just be patient and keep trying. If it seems to stressed with this try cup feeding first. It will have to learn your trustworthy. I have read where some are very friendly and like puppies and others are so grumpy you can only watch them like you do an aquarium. Luckily I'm an aquarium person.
Go very slowly. Get him used to your hand. Hand feed like dhscrusader suggested. If he won't come on your hand try placing a stick in front of his front legs for him to climb on. Good luck.
My girl was taking food from my hand but wouldn't come on to my arm, and my wee boy is the opposite. He looks at me like "what do want from me?" when I try to hand feed him, but he happily walks on me.
I say patience and persistence.
Ohhhh okay. Yea I guess everyone's right patients and hand feed. Sometimes he will crawl on my hand when I stick my hand in his cage and sometimes he will run into the tree and hide. I'm like okay? Emilio you were fine just last week what happened. Sometimes when I hold him he will turn like green with a bluish stripe tint, and when my sister tries to offer her finger to climb and take him from me he looks at me and looks at her and he crawls away from her I'm like what?!!! He loves me =D
