We have just the one Amazon but shes very hormonal and very sexual in her behaviors. Shes been this way since we adopted her a few months back. We asked a behaviorist how to help with these behaviors. A lot of it comes down to journal keeping. Write down what they do before the behavior starts, what happened during, who was where, what was going on in the room etc... Our journal is for aggression but also for constant masturbating.
Once you find the triggers you can work on preventing them. Our triggers were sleep, toys, cage placement, and over stimulated from a person (me her hated human). During hormone season progress moves at a snail pace so be patient. So far we have had great progress with 1- getting her 11 hours of sleep (wakes up much happier) This means no lights, no sound, we actually have a sleep cage for ours in a spare bedroom. 2- we move her day cage around from room to room. This helps remove territory aggression, as well as making life more interesting. 3- toys- we now rotate toys better, we also created our own foraging toys. (wooden blocks with holes drilled in them, nuts are crammed into the hole. She now has to spend the day working for treats. She chips away at the wood. This help stimulate her mind, keep her busy, and offers a reward. Its also a healthy way to release aggression)
I personally wouldn't breed or allow them to breed. There are so many displaced birds in rescues currently. I also see how our bird tries to "mate" with my husband and I can see the stress it causes.(and its not an over night fix to correct this, its months of training)
