Ah, the age old dilemma. The best thing I can say is to ignore it. Any reaction to her screaming, even just making eye contact, is going to reinforce the behavior. It is a sure test of willpower on both of your parts but remember, our parrots have the intelligence comparable to that of a 2-4 year old child, keeping that in mind always helps me. If the screaming gets you too flustered, just walk away for a minute. Go outside or into another room and take a deep breath, just don't give into her screams. You might also try making or buying her some new toys, things that are meant to be shredded and torn apart might help keep her preoccupied and cut down on the time she is sitting there yelling. They don't have to be expensive either, my birds like when I tie paper toweling around their cage bars so they can shred it to bits. Although, since you said she wants to mate, I don't know if that would be okay as she might try and use it as nesting material, hopefully some of our zon spe******ts could give more insight on that.
