Hopefully i'll be taking ABVP-Avian Specialty boards within the next two years, if I can get my case reports accepted by the credentialing committe. I'm boards eligible, I just have to jump through the hoops and get time to study, so take what I say how you want too.
As a bird owner, i have two of them. A 29 year old Amazon and an 8 year old African Grey. They are both very special in their own right. The amazon is mean as a snake, but funny as hell. He'll take your finger off and laugh at you while he does it. I didnt own him for the first 26 years of his life so he's got some bad habits (like moaning loudly like a woman having an orgasm and answering anything that remotely sounds like a telephone). he is very partial to blond females and hates all men if there is a woman close by. He hates men so bad he'll go after them and bite the shit out of them---which is why the previous owner got rid of him and why my wife is not allowed to open the cage when I'm in the shower----his 1 lb pissed off ass coming out from under my bed trying to bite my toes right after I got out of the shower and only wearing a towel and a smile was not a fun time in my opinion.
The grey is a trip becuase she cusses like a sailor thanks to my wife and her potty mouth. She's much nicer than the amazon.
A few things about birds in general:
1) birds will bite. The conure you are looking at is capable of taking a nice nip out of your hand. It will hurt and it will bleed. Be prepared to be nipped at least once
2) birds are messy, its the nature of a bird to make a mess while eating. You won't be able to change that
3) birds can be very noisey, depending on the species. Not all birds talk and not all birds scream. You can train them to talk, you can train them to scream, and they can make a lot of noise.
4) birds take time and attention. By nature the birds in the pet trade (psittacines) are flock birds. If a human takes on the role of the birds flock, you will have a bird that loves to interact with you. At the same time, there are birds out there that will kill a weaker member of the flock because its for the better of the flock to keep predators away. If you are percieved as being that weaker member, you and your bird will never be happy with each other.
5) most birds don't like to cuddle and be hugged on, but most birds can be trained to like a gentle scratch on the back of the head.
6) most bird species in the pet trade live a long time--some of them 40 to 60 years. The conure you are looking can easily live 20 years. Getting a pet bird is a long term commitment. Be prepared for that commitment.
7) birds have their own opinions. If you own a bird who decides it hates you, you are in for a very long road. Generally you will not be able to convince it to change its mind once that mind is made up
Humans have a very real allergy to bird dander---all birds, not just "downy" birds like cockatoos and african greys. Be aware of this allergy, especially if you have other allergies.
9) Most of all, bird in the pet trade--specifically psittacines---are intelligent animals. They do best in an evironment that challenges them to think about what is going on around them. They are also prey species, so the fight or flight response can be very strong. Give them something to think about, but don't scare them.
Let me know if you have specific questions.
