Considering adopting a rescue sun conure

Been thinking about adopting a rescue instead of buying from a breeder. Any experiences with rescue birds in Ontario? What should I expect in terms of behavioral challenges? Which rescue organizations do you recommend?

I remember when my African Grey went through this phase. I was so worried but my vet said it's actually really common.

I have a similar story. My Eclectus used to do the exact same thing. I remember being SO frustrated until one day it just clicked. Patience is truly the key with birds.
