I am happy to hear of your long term aim for your macaw.
When you wrote free flight, I hope you meant flight as in the home or in safe enclosed space.
Try to find the time to read a summary of my life with Tinkerbell.
You might find answers to questions that you have not even thought of.
If you are thinking in the future where you can allow your macaw to be flighted at home, try to read Tinkerbell Legacy - how to live with a flighted parrot at home. It spelled out the steps you need to take to create a safe home to protect against flight outside and what you need to do and prepare for.
That Tinkerbell Legacy start here
Free flights in the open is totally different. I hope you do not think I am hypocritical in doing free flights in the open while discouraging others from doing that.
But if you have gone into any of my writings when I did free flights, I always screamed out
FREE FLIGHT IS LIFE AND DEATH PLEASE DO NOT TRY THIS YOURSELF UNLESS YOU DO KNOW.
NEVER EVER FREE FLY WITHOUT THE KNOWLEDGE AS THIS CAN LEAD TO LOSS AND DEATH OF YOUR BIRD.
You know in the parrot world , flighted or unflighted, there are no such alphahood. That seem to be something transplanted from the dog world.
Not that I really know as I never kept dog in my life.
In being with equal and friend, whether humans or birdie, for good true long term friendship, there must be certain rules to follow.
Bending over backward be it for human or bird is very unhealthy and detrimental for good true friendship.
Riamfada used to do flying lunges on my wife...ok, just one time. I was shocked and told Riam in no uncertain terms, both with voice and with anger flooding out from my heart. Parrots are empaths. Being hypocritcal with them with sweet voices or silence while your emotions burn like a nova in the heart is wrong and confusing. No more flying lunges from Riamfada after that, at least to my wife.
Unacceptable behaviours must be made known and clear to the other party as soon as it happened. That cannot and must not wait for a later time. Decoy or deflect bad unacceptable behaviours to acceptable norms. Learn to read them and understand them. That will be most important in anticipating bad behaviour and stop that from even starting. Try to find time later to read
I saw that lunge coming when visiting Harry, but was too late to stop it. But caught by my wife in her camera. Hmm, and you might think of preparing the mash for you macaw too.
I wish you lots of fun and a good magical relationship with you macaw
