I would definitely say just visit rescues and shops until you meet the right birdie - personalities are so different from bird to bird, regardless of species. Mentally prepare yourself to commit to this bird for potentially the rest of your life, make sure you are able to afford upkeep, have enough space for the bird, and can commit the time and love they need. Then when the right bird comes along, you will be ready!
I knew I wanted a parrot after growing up with two Ekkies, I was really open to any type of bird that was the right fit for me. When I moved after graduating college, I made sure the apartment was bird friendly and paid special attention to the sound between units!!! (Live in an building with masonry separating the units, it is probably the best I could hope for. No doubt they can still hear Ollie when she's screaming, as birds do, but it's not unbearable). I saved up money, measured how big of a cage I could get, got rid of anything that wasn't bird safe, researched, researched, researched and then when I felt I was ready, I started visiting local places with no expectation to find the perfect bird on any visit. Love always finds you at the right time, patience is key.
I ended up meeting Ollie on a visit when she was 5 months old, and it was an instant connection between her, me and my girlfriend. Did a lot more research to make sure I was really prepared for a big bird like a macaw. We were able to take her home about a month later and she has been a light in my life ever since. She definitely has challenges and I know that there will be ups and downs (especially around puberty) but me and my girlfriend are committed to raising this baby and having her with us always.
