Well, a certain amount of noise is to be expected with a parrot, and while both are LOUD, there is a HUGE difference between vocalizations and screaming. It is YOUR job to figure out why your bird is making noise at any particular time, and address that in the appropriate way, kind of like when a baby cries

. You will also learn over time to distinguish between their noises, because each thing your bird is trying to communicate has a different sound to it (no joke, just takes a discerning ear. Learning to decipher parrot screams is like learning a foreign language). The first type are vocalizations known as "contact calling" or "flock calling" which is the bird trying to make sure their flock mates are safe. This type of vocalizing comes in VERY LOUD, short bursts, typically in the early morning or early evening. It's how they make sure their flock is all there an safe when they wake up and go to bed in nature, so it has to be loud to pierce through dense jungle. Typically this type of vocalizing only lasts a few minutes (or may only be a few loud calls) and is done. These vocalizations should not be discouraged, it is natural and just one of those things parrots do. Some parrots will quiet right down if you establish a contact call back to them to let them know your safe (such as a whistle or cue word). We usually have Kiwi with one of us whenever someone is home, but when you do have to leave the room without him, he will let out some calls and you can whistle back and he quiets down.
The second type of vocalizing is when the bird has no other means to communicate a need- they are bored, hungry, tired, scared ext... Obviously, if your bird is making noise for one of those reasons, you need to correct the situation. Give them more food, put a new toy in the cage, half cover the cage so they can nap ext... The key is to have an idea of what our bird is upset about and needs you to do for them so you can quiet them down.
Behavioral screaming is a whole different ball game than natural vocalizations. Behavioral screaming typically comes from long term neglect of their emotional or intellectual needs, which some people do not even realize they are doing. I have no idea how you function with your bird, so I'm just giving
examples, not suggesting you do these things, but these are some of the scenarios that can lead to behavioral screaming- The bird is not mentally stimulated. This could be from not having toys frequently rotated, being in a low-traffic room in the house, and not having 1 on 1 interaction time with their family doing activities that are fun for the bird. The bird is emotionally neglected. This could come from the bird being locked in the cage most of the day, the "favorite" family member is home less than everyone else, the "favorite" family member does not go out of their way to spend time with the bird when they are home ext... They can also learn to train you. As in, if they scream and you come back to the room (even if you're upset), they have just trained you to come running when they start screaming. That can become a really "fun" game for a bored, starved for attention bird.
Until you figure out WHY your bird is screaming, there is no cut and dry answer on how to modify the behavior. Think hard about why the bird might be screaming. If it's a natural vocalization, you work with the bird to establish more favorable verbalizations so it can communicate in a more pleasant way. If the bird is not having needs met, you have to start meeting those needs. If the bird is plain unhappy and starting behavioral screaming, that starts with meeting needs consistently before the bird screams and ignoring it when it does. All that said- can you give some more details about what times of day your bird screams, what precedes the screaming, do the screams sound "different" at different times/scenarios, the birds social interactions with the family and how often toys are rotated

That would help us help you better.
Wanted to add- when we got our BFA he was a BAD behavioral screamer. I have never heard an amazon capable of screaming loud enough you could hear him a block and a half down the street when he was in the house with the windows shut

It is my guess that would be the primary reason he went through 2 homes in 10 years, and it was EXTREMELY hard to train that out of him because it was so ingrained in his behavioral patterns. It is best to learn how your bird communicates and work to modify normal and natural communication patterns than to let it escalate to a point where it is non-natural screaming that drives you bat crazy or worse, you have to rehome the bird. It would have ben *SO* much easier to establish the good lines of communication with Kiwi if we had got him as a young bird. He's very intelligent and I have paid attention to him enough I can tell the difference between a "I'm tired" noise or a "I'm bored" or "hey you left the room mommy, are you ok" noise, and address each one appropriately. You have such a very young bird, do not miss you window of opportunity to address the noise making the easy way, because you don't want to wait or halfass it and go about it the hard way.
