Hey there --
I am having this exact same problem with my sun conure and it is driving me and my husband crazy.
We cover him up and this usually works for a little while. We notice that he does
this when its dinner time and if we are eating, he has to be eating but even if he
eats a little bit he still starts his jungle call again.
He just wants to be with me and I have made a bad habit of just getting him out of the cage.
My husband became so frustrated that I wasn't sure who to tend to first, my husband or the bird
and teach him right. Needless to say, the lack of patience on my husbands end made me
teach the bird that I would come to him when he screamed for a long time. So the cover
started taking the place. You know, though, I kinda think he likes being covered because
he starts playing so I don't think he feels like he is being punished at all. My conure loves
being up under a hand towel I have hanging in his cage. He cuddles up in it and the part
hanging on the outside, he crawls up under and plays. He loves that so the covering up
may be more of a play time for him.
I also noticed that his screeming started when I actually moved him and his cage to another
location in the house. Since that time, he screems more and has become very aggressive
toward other people and I am to the point that I have to put him up when we have company
over so that he doesn't hurt himself or someone else.
I am working on finding that magic trick. If I find something I will let you know. HOwever
I am thinking about moving him back to where he was but he will have to have a new cage
to do that with side guards so that it doesn't ruin my floor. I am concerned about
also making that change for him and how that will stress him out. So at this point, we
are bringing a new quaker into the house and I am going to go very slowly and let
him get used to the new baby for a while in his current cage and just deal with the screeming
until I can figure out when to move him back to where he was.
If anyone has any advice on this topic, I am in desparate need of some experiences that
others have had to help me.

Well I understand your frustration...I have the same problem a lots with Harley....He is quite as long as I'm out of the room and when I appear again, he'll start...I think it is an attention getter..so I start just talking to myself in a low voice or just humming and he will quiten down to hear what I'm saying....
If he starts again I've started saying in a stern voice...."no,--- bad boy, that isn't going to get my attention, so quiten down", and he has done that....Wow, to my amazement for sure....then I'll say "good boy"....afterwhile I may go and pick him up....
And too it is hormonal season and your baby could be molting.....Try a bath or misting, that seems to quiten Harley down for a good while when he starts to preen his feathers..
Good luck---let us know what he does...Just keep trying anything....
or give him time out in a dark room, preferably the bathroom, make sure lid is down...and leave him for say 5 or 10 and tell him when you leave him in there "time out"....that works with Harley too....Keep in touch....

Hey there Harley's Mom?
I noticed your photo of Harley in that blue housing? What is that and where did you get it? It is very cute
and looks like fun. Just curious?
