There's no deal because they don't learn to talk or whistle just within a snap of the finger. It takes time for this, teach him to whistle first, whenever you past by his cage, whistle to him, same when he's out of the cage. Talking might be a bit harder, depending on the bird really, some teach themselves to talk, and suddenly they'll say something and you'll be like "WHAT!?". Do the same as when you teach him to whistle talk to him when he's in and out of the cage.
As exciting as it may be doing this, it can't happen in an instant, so you can't expect anything to happen too quick. He may even talk before he can whistle or the other way around!
