I think it depends on the bird.
And I think it depends on the owner/household.
You're doing a fantastic job w/ Aries. I'd love to hear more.
Sorry, I wasn't clear. LOL I totally agree with you that the screaming depends on the owner/household. I meant that I think the morning/evening calls depend on the bird. As Aries doesn't really call in the morning and just kind of at night.
More? Hmm...well. His morning consists of chattering with me while I uncover him and making kissing noises when I take him out. It's the first thing he does when he gets to my finger in the morning. My husband built a nice little perch with removable crocs for food and water so he spends a lot of time on that throughout the day. It's really helped with the aggressive behavior he was showing when he was on my shoulder or wanted to be.
He spent time with me before I had to relocate and in that time he was learning a lot of great behaviors. I think this may be why it didn't take as long to get him out of the bad habits. He knew I wouldn't put up with being a cranky bird because he wasn't getting what he wanted. He's slowly getting used to being shown new things again.
He's never pushed to the point of frustration, but he is given new experiences and lots of love and praise so he becomes much more comfortable. He's a smart little guy.
Usually he's got 'nap time' he goes back in his cage to play and just be for a couple hours. It's the same kind of thing you do, to teach him that he's not being punished and that his cage is an ok place to be. He doesn't free feed in the cage though. He has tons of toys that rotate in and out. He will destroy a piece of wood when he wants to. He is kind of weird about toys so I have to keep mixing them up

We don't mind though.
He's a bit fluttery when we get near the cage, which I know is from being a bit cage bound. He is getting much better. We stand near the cage until he sits nicely on my finger and then he goes back in.
I do need to remember that he won't do everything he did before with me right away. He's been home with us for a week and a half now. I just have to keep reminding myself that with time he'll relearn everything. He used to do the 'bat trick'...now he won't, he doesn't like it and I think his feet need a little more strength. We're working on that kind of stuff.
He'll hold a full conversation of 'what' and 'oh' with you if you let him. He wants to talk so bad and gets frustrated when I don't know what word he's trying to say. It's not a big huff, just repeating the word to my 'what' about 10 times in a row. He's working on 'good morning' 'Aries' 'baby' 'nigh night' 'poop' 'hello' (which he says clear as day when a phone rings, but only then) and I think he's trying to say 'good bird' lol Something that sounds vaguely like 'Daddy' as well.
He's kind of potty training himself. He waits until he is on the perch for his morning go. lol The first time my husband saw this he was VERY surprised. We've had some success with going on a couple different things and not on us or on the furniture.
He's not perfect and I get a little sad some days that he's not as snuggly as he used to be and that he doesn't do all the same things anymore...but he'll learn again.
He's having a hard time reintroducing to veggies, though he still knows oranges. They're a treat and something he will do anything for

He was just pellets when he was there, and they gave him nuts like you wouldn't believe. I would go through and take away some things and tell them why. He'd still love to have nuts, but they need to be something he only gets when he's training in my opinion. He's getting used to spinach and broccoli again. Liking the whole grains again as well. He still loves his pellets the most

Trying to get him on the uncolored ones...but he's a sucker for the bright red and yellow ones.
Overall, it's a process to get him back to a mentally emotionally happy bird. I have my days and he has his...but I think we're doing ok at the moment. We brought him up first, we'll be bringing the dog and cat up next. He needed the time to adjust and feel safe. Rules change slightly with the other animals, but the cat was with me when I initially got him so the cat is aware of some of the rules. They never spend time together, though the cat thinks the top of the cage is for sleeping. Running a sleeping cat off a bird cage is...interesting.
