Please help. Out of control contact calls.

We have had our GCC for about a month. He was adopted from his original owner and hes about 2 1/2 to 3 years old. For the most part he is coming along well. He was a bad biter but is calming down with that.

The big problem is he is becoming clingy as in unhealthily clingy. I know these are social flock animals and were with him in the morning and evening and he gets at least 2-4 hours out of the cage per day with plenty of scratches and interaction. He is flighted and if you leave the room he will come with you 100% of the time. He is very afraid of being alone.

The last few days the contact calling when we walk out of the room and dont allow him to come has gotten out of control and we don't know what to do. We had his cage in our bedroom where we spend most of the time and in the morning when my wife gets up he was letting out 2-3 calls and settling back in while I got another hour or two of sleep. Now when either of us leaves his eye sight he starts flock calling and absolutely wont stop for extended periods. This morning he let out a loud contact call about every second for 1 hour and 40 minutes after my wife went to work. I am trying so hard not to go to his cage when he does this because I don't want to encourage the behavior but it's completely disruptive after and hour straight of loud screaming. Initially I was trying to always wait until he calmed down to go to him so as not to encourage him to call out every time he thinks of us. At this point I feel like I must be doing something wrong.

Ever consider having the bird in another room?? Im not one of those that think it causes problems responding to a bird doing contact calls. Its not like dealing with a spoiled child. Totally dif instinct here. Myself.. I call back. I also got my birds understanding they don't have to freak when I leave the room. I tell them "be right back" meaning exactly that (result..no contact calls).. Same thing if Im leaving the house for a bit... I say "bye bye" and ask them to get in their cage (which they do). They have learned what to expect.. hence the main calls I get is their enthusiastic greetings when I come back home from an outing.
Also.. going back to keepin the bird in bedroom. My bedroom is a mighty deserted place once Im up and kicking. So my birds are in my den with me where IF Im home its most likely the room I will be in.. and for the most part they stay out of cages unless I have to leave.
Again note.. its my feeling that these lil birds want to stay close in a flock for safety/security in the wild...its hardwired in to them. (hence the contact calls) That's part of their charm.. the desire to be close to you also. They are not a spoiled rotten child that needs to be ignored. (just my 2 cents).

My bird is alway on me when I'm home but he's figured out that if I say I'll be right back then he won't contact call, also if I turn out the lights it means I'm leaving for work.

Try lighting changes and verbal reassurances. I'm not going to swear this is a magic bullet conures are known for this attention seeking behavior, and will pretend to be in great distress to get attention. It might just take a few days/weeks till he figures out yeah the contact calls aren't working.

COntact calls are just that. The parrot wants to know where you are in the jungle of your house. WHen I leave the room where Salty is, i also will tell him I'm that i will be right back ( but you have to keep your promise otherwise you break trust). Be patient, be consistent, and dont give up.
