Training a parrot takes patience and skills. I have a quaker parrot that is now 4 years old and will be 5 years old this month. It is best to start training a parrot when it’s a baby. When it grows it can learn even more. First starting teaching it simple words like “Hello”, “Yes”, and “No”. If it repeats them at the right timing give your parrot a treat or something it really likes. Once it learns it completely you won’t need to give it a treat everytime it says the word. Having a parrot is hard work but it’s completely worth it. I have 1 parrot, 2 cockatiels, and 2 parakeets. My parrot talks the most out of all of them. African Grey parrots are also very intelligent. If you have a big parrot be careful so that you don’t upset it.
If you’re ever angry with your parrot be sure not to say any words you don’t want it to learn so that it doesn’t go repeating them to everyone. There are also more parrot books on amazon: http://www.amazon.com/Barrons-Books-Guide-Quaker-Parrot/dp/B0006G5E8Q/ref=sr_1_4?ie=UTF8&qid=1308234716&sr=8-4
If you are going to be getting a parrot anytime soon make sure to get it a good cage and plenty of food. Getting it some toys for its cage is optional but it helps a lot. Give your parrot at least 30 minutes of attention everyday. For more information about parrots visit: http://en.wikipedia.org/wiki/Parrot
