Yup Jim, I do remember that visit and your findings. And to that end, kept fighting myself with regards to using he or him as I was replying. And I think I did a really good job of it.
The normal Avian Vet visit is not based around a specific question like: If I start aggressively Flight Training my Amazon, are there any concerns or things I should be watching for?
Compared to an 'In Door' flyer, Amy's life is pretty much 'At Rest.' Nothing wrong mind you, but care should be taken when you transition from one level to a major upgrade in activity. That would be like me at my Doctor's office stating that I am going to start running 25K runs this coming weekend. After my Doctor picked himself off the floor from laughing himself silly, he would say: Nice idea, but NO! You need a detailed examination to see how bad your old heart and lungs are, let alone your muscle tone, etc, etc, etc,.....
Point being, Amy's Avian Vet visit was based solely on life as he is currently living it! If I tried to run a 25K this weekend, it could kill me, and I do not say that lightly. And, the same is possible for your Amy. Those huge muscles place a heavy demand on Amy's heart and lungs (air sacks) that could result in serious physical stress that could serious hurt your sweetheart. And neither of us wants that!
So Yes, seeing your Avian Vet is a must and being very clear as to why will be important so that the correct testing is done! And please, make it a point to being able to hearing Amy's heart rate!!!!
Our DYH Amazon is a 'In-House' flyer and compared to our YWA, his muscle tone and heart are at a very different level. By the way, an Amazon flying at your across the room or across the yard is a truly amazing sight, the only difference is the background!
