Ok, I really want to to stress some stuff, since these smart social parrots end up getting rehomed so much, or end up in a garage or outside. Because they are prone to plucking and screaming.
Quaker parrots evolved to live in huge communal colonies. The only species of parrot to build a community nest larger than n automobile, with seperate 3 chamber apartments for each pair .
Why is that info important? Because it shapes the whole quaker outlook.
They make noise because they are highly communications oriented, their brains developed that way. Because constant communications in their very large natural flock structure, living on top of each other surrounded on all sides by neighbors , communications are pretty important. Its not the decimal level but the duration of vocalization that can drive you batty. Breeding season in adults ~2 yr Olds can become extra vocal and extremely protective of their cage or home base.
Another important thing is their highly social nature. As they evolved for large complex flocks, that breed and raise young in large apart community nest with hundreds. Unlike green cheek conures who average flock size is 10 members, and us usually an extended family group. So quakers are highly socially driven. Personally im starting to think they shouldn't be the sole parrot in a household.
They are going to want a lot of attention ( always exceptions) more attention than my 2 GCC required. More preening by you of their feathers, and general hands on time.
They are also an active species. Like to be busy, lots if chewing, and manipulation of objects. As one would expect from a builder.
And plenty of smarts to go along with being so communicative , so social, and an engineer.
A quaker is not a species you can leave all day alone in a cage and go off go work. For all the above characteristics. You might get away with that while they are babies up until sexual maturity. But they are prone to self destruct and behavior problems like
cockatoos if their needs aren't met. Screaming, plucking, and self mutilation .
They are so prone to its called Quaker Mutilation Syndrome.

Do they make great pets, I think so. But only if your lifestyle, and idea of a parrot integrated into your life match. I love their social, vocal, busy nature.

" CALLS
Monk Parakeets are very noisy animals with a vocabulary that consists of at least eleven types of calls. Their most characteristic sound is a chatter of short notes that they give while perched or at their nest. Birds in flight make a loud squawking, with many calling at once. Monk Parakeets kept in captivity can learn to mimic human speech."
