Alison,
I believe 100% that he was self conscious about his burnt feathers. Parrots are proud, they preen and place their feathers just right. It must've been an awful, painful experience for him. What became of the previous owner? Do they still check on him, or did they ever?
We have been considering whether we should try to bring another adult parrot in. I have a friend that invited us to a meeting, a new group that formed in our area. A few of the folks dropped out of a well-known rescue group for various reasons, and started their own that really DOES focus on the birds. They have a few parrots that need homes. We have three here that had previous owners who did not want them anymore. Two were caiques, and they fit in very well, very quickly. But the last one we brought in that was an adult did not fit in at all. He had been returned to the original breeder after the owner had children. They 'didn't have time for him anymore' so she was reselling him. Full price, of course. He was an atypical pionus. She did not warn us of his antics. Only said that "if you forget to tell him good morning, he'll let you know" He has a huge vocabulary, but very loud screams, very often. I wasn't prepared for that, nor was the rest of my family, including birds and dogs. He really disrupted our household. (not just the humans). I thought I found him the perfect home; someone with conures who was used to loud screams now and again. I was fully honest with her, as I did not want to see him bounced around. Handsome bird.. she stuck it out for a year or so, but has been posting him for sale in the online classifieds, as was pointed out to me. He was meant to be a breeder, and was not being kind to her females. I don't think he really had his own space there, though. Looking back, if the person I bought him from would have been up front with me, I don't think we would have brought him here.
I've since learned that the questions I asked ahead of time only scratched the surface, and there will be more involvement into the past of any that we consider re-homing here. As Dave reminded us, it's no easy task. Maybe in another 10yrs I'll be much wiser, but I have already learned a lot from you, Michael and Dave. And there will be no more jumping the gun when it comes to the balance of our household. You'd be surprised how much anxiety can be caused when a 9-yr-old cannot focus on her homework which has to be done after choir in 30min while she eats before leaving for gymnastics.. such stress already! And my poor golden retriever.. he would just cower and hide when Joey started yelling. Any remedies were short-lived. He just did not want to be here.
The meeting is on the 12th; I've got mixed emotions but fully trust my friends and the company they would keep cannot be that bad.
