I honestly think for the birds sake it is best to wait. I honestly think for your sake it is best to wait. Did you check out the links Zara posted? If not, please do and then search for more!
If your parents wanted a bird that may be very different but to put the pressure on them to get one without them knowing everything they need to know (and not just the nice fun stuff) is totally unfair to them and very very unfair and irresponsible to the bird. The things they need to know is stuff they wont want to bother learning unless it is them that is emotionally invested in bringing a bird home...... we see this stuff all the time. Birds getting covered when they should not be because people want to sleep in and dont like the noise, birds being sprayed and mistreated to scare them into silence, birds getting sick and not being taken to the vet- left to slowly die in agony, toxic substances being used around the bird, the bird being shoved in a wardrobe, shed, laundry to get it out of the way or shut it up, the bird being cage bound because we don't want bird poop on carpet or furniture, the bird getting put into a tiny cage because the cage doesn't suit the decor of the house or the cage is in the way, this list goes on for ever and is seriously so wrong and heart breaking..... when you are not an adult you have very little say on how these situations should be fixed, handled or controlled and the bird will suffer for your lack of say over your life and home environment.
If you are going to college then that is very unfair on the bird- they deserve their owners to give them a birdie lifestyle not just food and a cage and some attention when the owner has time, is bored or can be bothered. Birds like routine, they like company, they need exercise, they like to be able to live like a bird should (which is messy, loud, and very very expensive and time consuming) - most of these things do not work out so well when you are not even fully in control of your own life yet and are not sure what that will even look like.
I do not mean to be horrible but I really think you need to do the biggest search through this site for others in your situation and see how terribly it so often ends for the bird.
