I watched this squirrel monkey for quite a while, running up and down a tree with two of his friends. They'd grab food off the tray and then scurry up the tree to eat it. He's actually holding a grape in his mouth and in his hands, looking up to see if one of his friends is coming back down the tree to chase him away.
