I agree Mike, It all depends how they are raised. I know some members in my Club play very agressive with their Macaws and as they mature and now out of control all of the sudden want a nice calm fun loving gentle Macaw. In my head, I'm say really? The hard part about raising Macaws is, it's all in what you put into it. I always say, If you want a wild child play rough, if you want a loving gentle Macaw, show it while they mature. I have seen many cases where an out of control Macaw was rescued and just wants to bite everyone and anything it get's it's hands on, with lots and lots of work, turn around and almost reprogrammed to be a loving Macaw.
I do wish My Green wing would go to more people then just me and my Vet. When he was a baby, he used to go to everyone, I beleive that not being fully weaned and after a rough start in the world, he really bonds with me and Vet. The reason I joined my bird club was to attempt to get him used to other people. To this day, he only wants to be with me. Any Advise. Joe
