Yes, as the others said, touch takes time. Just spend time in the same room talking to him and whistling. Slow and easy wins the day on trust. As to the vegetables, you can make "chop" (search forum for threads), sneak it into things like birdie bread, hang it on a skewer (my TAG's favorite way), or find another way to sneak them into something he does like. Sometimes you just have to keep offering the veggies. One of these days he will give them a try. Some they like better cooked (sweet potato for my bird), and others they like raw. It depends on your bird. It is a lot of trial and error, which results in a lot of waste, but you'll figure it out eventually!
