You may also be rushing him.
If you’ve only had him a week, having him in a space where he can see you is totally fine; but you may want to keep your distance if it seem to agitate him.
Once you can get close to the cage without provoking a drastic response, you can “slowly” work on taming.
If your bird(s) come from a breeder that worked well at socializing their animals, then the process below is the same but it may go much quicker for you. You should move at the pace that your animal is comfortable with.
If you place your hand in their cage and they hop right onto you, then you can start building from there with treats, training and out-of-cage time.
If you got your bird(s) from a pet store, or a breeder who doesn’t socialize their animals; your bird(s) is going to need a couple of quiet weeks to settle in. They can seem “tame” at first, but this is likely just because they are frightened and submissive.
Start by resting your hand on the outside of the cage for 5-10 minutes a few times a day. Talk to them as you do this, in a quiet and steady voice. Read something to them if you like
After a week or two of this, you can move to just placing your hand "in" the cage. You can use their behavior as a judge on this one. If they actively retreat from your hand, even when it’s on the outside of the cage; they aren’t ready for you to go to the next step. Once they start to essentially “ignore” your hand, then you can move on.
The next step is to put your hand in the cage. Don't touch them, go near them or even move. Just rest it there for the same 5-10 minutes a few times a day and continue with the quiet, steady speech.
Your bird(s) will eventually begin to acclimate to you and slowly move up to investigating your hand. Then you can work on treat placement in the hand to see if you can then lure them to step on it to eat from it (again without moving).
And then you go from there!
This could take weeks, or even months, of work and is entirely up to the bird. You may get lucky and have a very outgoing animal that tames in a short period of time, or you may have a more timid creature on your hand that requires a lot more from you.
Birds require far more patience with training than dogs and cats do. They all know instinctively that they are "prey items" and we are basically asking them to ignore that natural response when confronted by a larger predator (you).
