Sun conures?

I read once that they only get louder when you have multiples XD So that was probably a big part of it.

I have found that is true regardless what species the other birds are. Once one starts screaming flock mentality kicks in and they all start screaming.

In my experience conures are louder in volume, but hans macaws are a lot more loud in duration of screams & frequency of how often they happen.

ok i only read the 1st page of responses but i have to add this input...
although i have only cockatiel experience it is quite well known that parrots, big and small alike, usually get loud when they're "establishing contact with their flock" known as "contact calls". they want to know who's around and where they are. it's how they communicate with each other out in the wild so naturally it's how they do it in our homes.

With conures they have different distinct calls. The "where are you" call isn't very loud and it's one note with a long gap in time between them. When ours wants to be let out before anyone is awake he'll do the same note, pause for a few seconds, and do it again until someone gets out of bed to uncover him. If someone walks out of the room he'll make the same call to try to get them to come back. He'll do the same "where are you" call to try to interact with the birds outside in the wild. Sometimes they'll respond back.

Then separately is the "I am pissed off" scream which is similar to the "I am scared" scream. When ours wants something and isn't getting it, or just wants to be an ass, or is scared for any or no reason- it will scream and scream and scream until it's covered up. We can't let ours see outside at all because seeing any bird outside [especially crows] will trigger the "I am scared" scream. These two screams don't seem to be happen in an attempt to "call for someone." The "I am pissed off" scream is one note repeated twice at high volume, a short pause, then again. The "I am scared" scream is this same note but played continuously on repeat with almost no pause between it.

Separately the bird has some playful noises it makes while it's being played with, but they're not loud at all.
