Reddit reviews The Second-Hand Parrot (Complete Pet Owner's Manual)

Thank you for adopting a rescue! My little dude is a rescue, too - I adopted him when he was approximately 5, and he's 21-ish now. The best advice I have is to look up parrot clicker training on YouTube. My bird isn't clicker trained, but had I known about clicker training when I first adopted him, I probably would've tried that. Conures are huge birds in tiny bodies, so if you look up training for large parrots, it'll work for conures. My favorite books on bird training are by Mattie Sue Athan - she wrote a book about rescue birds, and another book called Guide to a Well-Behaved Parrot, which I own.

Be patient, be CONSISTENT, do not waver from your routine, and don't react when he bites and/or screams. My conure is a bigger bird - he's a cherry head, and he's got a huge beak for a conure. His bites hurt REALLY bad. I went through about two years where I had to layer multiple sweaters and hoodies every time I took him out so I couldn't feel the bites; otherwise, I would react because it hurt so bad. We had days where he'd bite, and I'd go into the other room and cry my eyes out because I'd been struggling for years and I thought we'd never get past the biting. But I promised him when I brought him home that I'd never give up on him. Now, he's downright cuddly - he respects me as flock leader, and although he's cuddly on his terms, he respects my terms (no biting, contact calls only in English, step up when I say so, go in the cage on command).

One of the first books i bought. The second.
Used copies can be got for $5-10 with shipping.

Check out location sanctuaries or even try to find a local 'guru' that might let you foster a 'tiel so you can see what's it's like before committing. and if you go with a breeder, please double check that their practices are sound and not a 'backyard breeder' churning out babies for cash. The difference btwn 'find a bird that likes you' vs. 'come pick one out, it's $400' kinda attitude.
