Thats great Dee, you are doing the right thing in watching to see when he gets a little nervous and wants to return to the safety of the cage, it won't always be that way. The day will come he will be more used to you and feel comfortable and love being out with you, you will be asking us how do you get him off you. You are a patient woman and it will reward you soon enough, what a great parront you are becoming.
Love that picture of Juno enjoying that banana, wish Josey would eat banana but she turns her beak up to it, thanks for sharing that pic with us.
