Considering adopting a rescue African Grey

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?

This happened to us last winter. I think the shorter days and dry heated air were the cause for my bird.

Oh my bird did this for about a few days and I tried everything. Honestly, time was the biggest factor. They just grew out of it.
