Yep, that sounds good.

If your interested in doing further training with him, there is a book called "Getting Started: Clicker Training for Birds" by Melinda Johnson. It goes over that as well as telling you how to teach tricks. It also discusses how to tame birds and end aggressive biting and how to calm fearful birds. It's done using ALL positive reinforcement.

It uses methods similar to the one you posted, but instead of saying GOOD, you click the clicker, then give a treat.

The book explains it very thoroughly. I highly suggest getting it as it will really help you out, strengthen the bond between you and your bird, and will give you the opportunity to have fun and enjoy owning a parrot.
