Was cameo a re-home? Not sure if you've had a re-home before or not. With a re-home Too, I would EXPECT a lot of screaming for the first year or so. Tasha has been through a lot, with changes in her old home and now being moved to yours. Toos just don't deal with major life changes very well. She probably is going to take longer to transition into your home. With any re-home large Too, it can take up to a year or two before they accept their new surroundings and settle in. The 'honeymoon' period usually lasts a few days to a month and then they realize that this is really their new place and the screaming starts. The screaming is for sooo many reasons: testing what she can get away with, uncomfortable in her new environment, doesn't understand the change in her normal daily routine, missing her old owner, and simply just not happy yet in her new place. She might be calling out to you to. You said that she is really comfortable with you, she may be calling out to you for comfort. They are on the level of a two/three year old child. In her eyes she was taken from everything she knew and is now living in a strange place with people she doesn't know. It would be unfair (and completely unrealistic) to not expect her to scream a lot in the first few months to a year.
Rome didn't touch a toy for about 6 months or so after coming here. She didn't really start to actually play with them until around 8 months or so. Around 8 months is when she started to settle and stopped screaming. For 8 LONG months, she screamed all the time. It isn't easy for them to transition. Their world has completely been torn apart and they've been given no say in what happens in their life.
With an adult Too that comes from an environment that they are happy in is a way more difficult re-home than one that was completely neglected. She loved her family. Right now she feels abandoned and shes not happy about it. Toos are extremely sensitive birds and she doesn't understand (nor is she comfortable with) the environment that shes in.
Its not easy to take on a re-home Too, but the rewards are so worth it, if you can hold out long enough for her to settle. I always tell people, if your getting a re-home large Too, expect the absolute worst behavior for the first year and if you think you can handle that then try to take on the bird, if you think that in the slightest bit you cant then its not fair to the bird to even try. I would suggest getting a pair of ear plugs for you and your wife.
I agree with MareMiller, I really think a Too does a lot better if they can spend the majority of their time outside.
