I would first have your parents look into it. Major Mitchells, at least in the United States, are expensive, hard to find, birds. What are they selling the bird for? I would be careful this isn't some type of scam. I completely understand your desire to help this bird and I think it's admirable. We have had young people on here with cockatoos that are excellent bird owners. However, a cockatoo is a big responsibility. Are your parents on board and committed to its care? Any parrot is really a family bird. Since you've had birds before, I am assuming that your family has already made the necessary changes to the household - no teflon, no candles, no febreeze etc. A cockatoo can live 50+ years. So depending on the age of this bird, you could be a senior citizen and still have him. Are you ready for that? Do you want to go to college, travel, etc? Are you parents willing to take care of your bird while you do these things? And cockatoos are expensive to care for. They need a very large cage, lots of toys, proper food and vet care. Again, is this something your parents are willing to do? And knowing nothing about this bird, he might not be handable. With proper training, I think any parrot can become "tame" but you don't know where you're starting with this bird. I, of course, want this poor cockatoo to have a wonderful home but I want you to think things through WITH your parents. I don't know that Major Mitchells are any more bitey than any other cockatoo. I will say in general, with any cockatoo, at some point you're going to get bit. I have scars on my hands from cockatoos. It can be daunting once you've been bitten to go back and handle a bird. But you have to try to stay calm and then figure out why you got the bite. I feel it's almost always "our" fault that we got bit and not the birds's.
