Parakeets are a extremely loud bird!!! I have one my self and it is really loud!!
I am not sure what you are asking, but my guess is you want to know what pet bird is one of the noisiest? Or maybe you want to know what wild bird is keeping you up at night?
If you are asking about a pet bird, then the noisiest would be pretty much any in the macaw family.
As to wild birds, then the northern mockingbird is one of the most constant talkers, sometimes going until 10 or 11 at night, only to resume at three in the morning!
