Don't ever force your parrot out if the cage.
I feel your frustrations. You got a lovely new bird and just want to be freinds. But it's going to take time and effort, as your bird is fearful.
Say the same thing everytime you approach the cage. If you get to one foot away and he gets upset. Stop there, put a chair their for you to sit at. Talk quietly to him, don't stair right at him. And wait till he is calm. Then tell him what a good bird he is and get up and walk away. Come back in a few minutes, say hello , and sit and wait till he is calm while you talk to him. Then see if you can move the chair a few inches closer , abdvwsut till he is calm again. Tell him good birdie again , and walk away. And repeat it all again in a few minutes, each time moving the chair a little closer, but trying to keep him calm. Your goal will be sitting next to the cage your body sideways, and he remains calm. Have a great dish on the side if the cage, and when he is calm with you sitting there, put a seed in the dish and day good birdie and walk away. Then rrspeat several times, wait till he is calm for a few minutes, say good birdie, out the treat in and walk away. Repeat until there is no bad reaction when you walk up to sit in your chair by him. Then put the treat in the dish and stay sitting there calmly talking to him till he comes to get it. Then say good birdie and walk away. Repeat that step several times, until he will come right to the dish as soon as you out the seed in it. Then sit there a longer time and put another seed in the dish. This process can take a day, several days or a week. You are shaping his behavior, you are showing him you are good. You also have to use a high value treat, like a sunflower seed, a safflower seeds, a tiny 1/2 piece if millet spray, something that is his favorite and small. After he takes treats andvwsits by dish for second treat, try giving it by hand. Once he takes them by hand. Then walk up to the cage several times a day and say hi good birdie and give him the treat and walk away. Then set a perch so when you open the door the perch is attached to the door a d swings out. Put a treat fish on the outside of the cage door in an easy place for him to reach it. Put perches and a treat dish on top of cage. Then say hi have your chair there, open the door and just wait. If he comes over out a treat in the dish and tell him good birdie. If he is calm and takes the treat. Then give him another one. Then put a treat in the fish on the top of the cage in the he treat dish and just sit and wait. If he comes out and goes to the top to get the treat tell him how proud you are. And just sit and hang out for awhile. Then put some really yummy food in his cage a d tell him time to go back. A d back you chair up and wait for him to go in. When he he is in tell him good bird close the door a d wk away. Do the same thing the next day. Have lots of toys treat, pet he's on the top of the cage. Keep repeating until it's smooth and no stress on him abd he likes to hang out on top of the cage. Then I would start working on step up. That's the best I can explain it. It has worked for me with rescues. Also her is a link
