Firstly Laura, just getting caught up and read about poor Neptune. My heart aches for you.
We've had Bertie just over a year. He's almost 7 years old. We adopted him from a Parrot Rescue Centre. He was there because he was 'aggressive, biting and SCREAMIMG'. His life was the 'cage'.
With respect to managing the screaming, we said 'hush quiet' in a whisper. If he didn't stop (not a happy screamer by the way), we covered his cage until quiet, then off with the cover and verbal praises. We did this often the first two weeks as we moved to more out of cage time (concern with the aggression and protecting Ellie).
Within the 3rd week, if he started to scream the whisper of 'hush quiet' worked and he started to whisper back. He has only screamed in 'fear' since if he is startled by a loud noise. He doesn't like loud noise so we get his attention and say 'noise Bertie' (before starting the blender for example) so he doesn't scream when alerted to 'noise' en route.
I know it worked for you, but I'd not recommend covering the cage due to screaming (1. because it messes with their light cycles, which regulate hormones and immune health and can actually increase screaming long-term, 2. because it can make covering seem like a punishment if your bird dislikes it and 3. because some birds like being covered (as they seek out dark spaces) so it can sometimes even encourage the screaming behavior in certain instances)...It also relies on distraction/shock vs the bird making a choice to stop screaming out of the realization that screaming isn't working.
I agree with everything else, but not the covering. I suggest walking away and waiting it out instead (yes, it could take a week with 4+ hours of screaming a day, but with the proper motivation and maybe some earplugs, it will eventually stop)...assuming the bird is getting adequate time and attention aside from these planned periods of ignoring.
When Noodles does her happy scream (which happens when I am with her and she is excited) I imitate a quieter version back to her. It's like a game now. I go high pitched, she goes low and vice-versa. She sounds like a weird chicken because what started as "BACK BACK BACK (because that is always here favorite thing to scream, even when I am with her) is now "baaawwwk bawk bawk bawk" LOL We do not play this game for attention screaming.
You are right about the 'covering' issue if done incorrectly Noodles. I've been away for awhile and you have humbly reminded me of the need for 'clarity' in writing responses. Thank you.
The 'cage covering technique' is not a favourite for most but recommended by vets when applied correctly and appropriately. Leaving the room didn't work for Bertie and earplugs didn't work for Ellie, our dog or my husband

so I had to come up with something. Bertie was given a clean bill of health by a CAV so 'attention screaming' was the issue due being 'caged' for so long. Here is the technique that we used:
[FONT="]Try to maintain a relaxed atmosphere and attitude around the bird. Loud music or voices, shouting or having the television turned up will only increase the bird’s volume. [/FONT]
·[FONT="] Do not respond, positively or negatively, when the bird screams. Do not shout, scream back, and make eye contact. Even walking quietly to the cage to cover it, by bringing you to the bird may, in his mind, constitute a reward for the behavior. Nonetheless, covering can work well, if done properly and consistently. [/FONT]
[FONT="] [/FONT]
[FONT="]The cage should be half covered at all times, and should be located such that you can approach it from behind, unseen by the bird, and unfold the cover over the forward facing, open side of the cage. If the bird sees you approach, he will perceive this as the immediate consequence of his screaming. The behavior will thus be reinforced, in spite of the “negative” consequence of covering.[/FONT]
·[FONT="] Cover the cage for no more than 10 minutes, and consider using a timer, which when it rings, lets the bird know that the covering has come to an end. [/FONT]
·[FONT="] It is important not to use the cage as a place of punishment. Most birds who scream are insecure, and perceiving the cage as a place of unhappiness and isolation will only compound the problem. [/FONT]
·[FONT="] Birds often actually prefer to have their cages partly covered, and have been known to scream until the cage is covered, and then to stop. Covering the back half, or one side of the cage at all times suits many birds. [/FONT]
·[FONT="] Try to distract the bird with an indirect response to his screaming. While you continue to ignore the screaming, hum, sing quietly or whisper, without making eye contact. [/FONT]
·[FONT="] Never spray with water, beak flick or otherwise threaten you bird. Punishment and violence do not work and may seriously damage the relationship between you and your bird. [/FONT]
·[FONT="]
Do make a fuss over your bird when he is playing quietly or making pleasant sounds. Make a conscious effort to reinforce desirable behaviors, by telling what a wonderful boy he is, or how beautiful and clever he is.
