Dan has offered you great advice,i will just add..
If your bird is not receptive, start training in a room out of sight of your bird’s cage. Less familiar surroundings are likely to improve cooperation.
Pick a relaxed time with no distractions – a bird that is preening or eating is not going to be very receptive to training.
Practice in short, frequent sessions
Use lots of positive reinforcement; never hit or scream at your bird.
Always end your training session on a positive note, if your bird is struggling wait for a successful try, reward your bird lavishly, and move on to something else
