I think that ParrotGenie said it best..."There is no such thing as a "starter bird"...Took the words right out of my mouth before I could type them...
Unfortunately a lot of people go out and by their young kids an American or English Budgie or a Cockatiel, because they mistakenly think that Budgies or Cockatiels are "starter" or "beginner's birds". Hell, half the time people don't even think that Budgies or Cockatiels are species of parrots! I can't tell you how many people I've heard say "I want to get a parrot eventually, but for now I just have a Budgie/Cockatiel"...And I am sure to correct them every single time, because Budgies and Cockatiels both are not only parrots, but they both have the intelligence of a 2-3 year-old human child!!! And they both need many hours of out-of-cage-time and direct attention and interaction every single day to stay happy and healthy...
And the other mistaken "fact" that people hit me with all the time at the Rescue is that Budgies only live on-average between 5-10 years!!! Yeah, if you treat them like people normally do, lol...My first Budgie lived to be just shy of 19 years-old, with the record being 29 years! So my point is that ANY AND ALL PARROT SPECIES need the same amount of love, attention, and time from their owners, along with the same quality of daily-diet and the same quality and standard of Avian Veterinary Care!!! So don't let anyone tell you that a Green Cheek Conure is going to be less-challenging, need less time or attention, or require less care, or be less-expensive than a Macaw!!! Because that's exactly the attitude that causes smaller species of parrots to live much shorter lives than they should in captivity, and that also makes their lives not even close to adequate for them!
Here's the thing: I don't know how old you are, you spoke about your "parents", so I don't know if you are still under 18 and living at home, or if you're in college, etc. But what I can tell you is that if you are still a kid/teenager or a college-student, you need to think about what your plans for the near-future are, at least for the next 5-10 years depending on your age now, and you need to think long and hard about how getting ANY SPECIES OF PARROT is going to factor-in to those plans, because I can tell you with great authority and certainty that if you are under the age of 22 (more like the age of 25) you have no idea what life is going to throw you...And the reason I'm telling you this is because one difference with a Macaw versus SOME species of parrots is that they tend to be "one-person" parrots, and if you are still living with your parents/family right now and you bring home a Macaw, you have no idea who he/she is going to bond-closely with, that's the first issue...Just because you would be his main care-giver doesn't mean that he'll bond to you...And forgetting that issue, if you have plans in the near-future to go away to school, chances are you won't be able to take your Macaw or any parrot for that matter with you...So who is going to be responsible for your bird every single day, all day long? These are the kinds of things you need to think about, like having to move into an apartment...Most apartments don't allow pets, and if they do they probably won't allow a large bird like a Macaw. Then what do you do? Now if you're already an adult and I took what you said the wrong way, and you're already set in a house and a job, then some of these things won't apply to you, but you still need to think about the future: family, kids, etc. and how a Macaw will factor-in to that...
****Here's the other thing that you need to really think about right now, probably more-so than anything else: Let's say you go out and bring home a baby Green Cheek Conure right now...Keeping in-mind that Conures in-general are probably the most-social of all parrots, and they all require an enormous amount of time, attention interaction, and love to be happy and healthy, every bit as much as a Macaw (I speak from experience due to the Yellow-Sided bugger who is sitting on my shoulder as I type this)...GREEN CHEEKS LIVE BETWEEN 30-40 YEARS IN CAPTIVITY!!! So a Green Cheek Conure isn't going to be like a "Starter-Bird" or "Beginner Bird" that you can bring home now, bond closely-with, treat like your own child, and then 5-10 years from now go "OK, now I'm ready to get my Macaw, my REAL bird! People do this ALL THE TIME, and it makes me sick every time I see it happen at the Avian Rescue I work out...People surrender their "smaller" parrots all the time, parrots they've had for 5, 10, 15+ years,
because they decided to get "a REAL bird", like a Macaw, Cockatoo, Gray, or some of the larger Amazons, and they "didn't think it would be fair to the little bird anymore, because the new, big, REAL bird is going to require all their time and attention"...Happens all the time, probably once or twice a month someone surrenders their smaller species of parrot because they've put a deposit on a baby Macaw, Cockatoo, etc. It's like they were using the smaller species of parrot for the first 5-10 years of their life as a "training" bird that got them ready and prepared to care for a bigger, REAL bird...It's very upsetting to us, watching people just drop-off their babies, sign the surrender-paperwork, and walk out and leave them forever, and it doesn't typically even seem to bother most of them because all they can think about and talk about is their "new baby"; they're so excited about picking-up their new, bigger parrot that they don't even care about tossing-out their first little baby bird...Tons of Budgies, Love Birds, Parrotlets, Cockatiels, Green Cheek Conures, Sun Conures, Jenday Conures, Indian Ringnecks, Quakers, and even quite a few Senegals, Pionus, and Amazons...And believe it or not, in 8 years of working at the same Avian Rescue, we've had 2 different sets of people, one was a single woman in her late 20's and the other was a married couple in their early 30's, who both surrendered their Timneh African Grays because they were "stepping-up" to a Congo African Gray (the single woman was the one who actually said that to our Director when she asked her why she was surrendering her 14 year-old Timneh that her parents had gotten for her as a little baby when she was in Junior-High School, she told her because she was "Finally able to afford to step-up to a Congo African Gray", and didn't think that she'd bond-closely enough with the new Congo African Gray if she still had her Timneh...The bright-side to that story is that our Director was so upset about how that woman had just thrown-away her little Timneh, who by the way is the sweetest bird in the entire world, that she took her home the very first night after she was surrendered, and she never brought her back to the Rescue; she still has her and loves her more than anything in the world).
My point here is that the idea of a "Starter/Beginner Bird" is such a falsehood that the end-result of people who go-into getting a bird with that idea in their head is usually that the bird's life is of a lessor-quality than it should be, and the birds usually end-up either being re-homed after a short period of time...
***So the bottom-line to this is that if the species of parrot that you really, truly want to own and to add to your family and that you know that you are going to ultimately have is a Macaw, then you shouldn't even think about getting any other species of parrot just so you can simply get it right now, where you might have to wait to be able to get the Macaw...And you certainly CANNOT AND SHOULD NOT EVER go out and bring-home ANY BIRD AT ALL because you want it to be your "PRACTICE BIRD"...That's awful!!! Once again, a Green Cheek Conure isn't going to require any less time, attention, effort, or money in the long-run (the only difference in cost between owning a Green Cheek Conure and owning a Macaw are the "Upfront-Costs", meaning the cost of a hand-raised baby Macaw is going to be quite a bit more than the cost of a hand-raised, baby Green Cheek Conure, and the cost of a cage is going to also be more for the Macaw due to the size difference, but other than those "Up-Front Costs", the cost of owning and caring for either bird is going to be pretty much the same, the Certified Avian Vet care is going to cost the same, the high-quality, varied diet is going to be the same, the cost of toys and all the little accessories and such is going to be the same, etc.)...The Macaw is going to require more interior space in your home as well, but in-general what is going to be required of you is going to be exactly the same...
