I have 4 Green Cheek Conures, and 1 Indian Ringneck.
All 4 of my Green Cheek Conures are different.. Taji is hands-off, and prefers male people. Lola and Ozzy are my newest additions who are re-homes, they are more bird-birds, they have each other, and they are happy it being that way. Leila is my velcro bird who would be attached to me 24/7 if she had it her way, and I can do pretty much anything with her. Each one of them are still perfect no matter what, and I have no regrets, they are wonderful and very clowny with a big personality. Lola and Ozzy can get incredibly loud when they want to, Leila and Taji can too when they both start screaming, but when I had just the one Green Cheek Conure, she was hardly ever noisy at all.
And my Indian Ringneck, well he is kind of different to most Indian Ringnecks. He is a real sweetie, loves attention, and is really affectionate, myself and one of my brothers can give him scratches, and kisses, not all Indian Ringnecks are like this, and some can be hands-off, but it depends on the Indian Ringneck. He can get loud, as most Indian Ringnecks can, so I would take this into consideration, especially if you have close neighbors.
If you want a more hands-on, quieter (keep in mind all birds are capable of getting loud though) bird, then I would suggest a Green Cheek Conure.
