Thanks. I have one other question regarding books. Is the book "Guide to well-behaved parrot" still a useful tool. I have read it and some of the things seem to apply but to me it feels kind of outdated. I do have a clicker and the book which I will begin to use once I have read the book thoroughly and feel that I can do it effectively.
I have not read the book you mention, so can't help you there, but had to comment on your clicker comment.
I clicker train my birds. I look at it as a way that all of us (my birds and me) can have fun. While I agree that you need to understand the basics, don't worry about doing everything *perfectly*. I've made tons of mistakes, and have gotten better. I found that it really all clicked (ha!) in my head once I started working with my birds. As the book recommends, I started with my easiest, most forgiving bird first.
Of course, if you were training them to do shows or expected to make a living at this, my advice would be different! But just keep it in mind that it's supposed to be fun and if you do something wrong, no big deal.
