Welcome to the forum! What's your guy's name?
I don't know your experience with birds, or how long your guy has been in your home, so I'll offer some thoughts which might focus the discussion.
First, birds are intelligent active creatures and do best when they have things to keep their minds engaged. What does he have to keep himself occupied when he's stationed somewhere that causes him to be anxious? Does he feel safe there? Can he see what's going on around him? Could you create a play station that's his, with activities he enjoys, where he still feels part of the action? Would he enjoy the stimulation of music while he doesn't have your attention? There are some areas of the forums dedicated to enrichment that have some great ideas.
I talk to him every thirty seconds to try to entertain/calm him down hopefully but that doesnt really help he just goes back to being restless right after.
Second, we reinforce what we reward. Your statement about actively trying to talk to and calm him, doesn't allow him to develop the skills he needs on his own to
calm himself. If you ignore them for a while, but eventually succumb and do something for him when he makes anxious noises, you're training him how to get your attention. One way to train calm behaviour is to reward it. If you're able to ignore the anxious sounds, but still pay attention to he demeanour from afar, you could then choose to engage with him or reward him when he's calmed himself. Related to this, there's also the notion of "capturing" a desirable behavior -- as soon as he makes a pleasant sound or says a word between the anxiousness, that could also be a good time to engage or reward him. The key here is to be very aware of what we're rewarding.
Third, could you leverage his natural rhythms to avoid anxious situations? Are his energy levels elevated at specific times of the day? If so, you might consider leveraging that knowledge to adjust your schedule around his (mine are lower energy in the evening, so them being low key during an evening activity is easier than when they just woke up). There's also nothing wrong establishing a "nap time" routine when your guy is securely in his cage, and allows you to do focused uninterrupted work (I find late afternoon after they've been fed works for my guys). I do this even if I have nothing else to do, just to ensure my guys are comfortable on their own.
Lastly, routines and habits are important, and might shed some light. For example, I'm usually home, so it's not unexpected that mine are out of sorts after I return home on the rare occasions I'm out for the day. I also live alone, so it's to be expected they're on alert when somebody visits.
My Severe occasionally makes anxious noises too, and it
is grating. One last thing to pay attention to is our own moods. If we're anxious, that can trigger our animal companions to be as well. It can also cause us to have a shorter fuse, and a behaviour that doesn't normally aggravate, suddenly does. I'm fairly calm, and low stress, but even I have to keep this in mind during these trying times.
Eventually we learn what's triggering an undesired behaviour, how to redirect it to healthier one, and create an environment for them to be happy and comfortable.
Thanks for wanting the best for your guy.
