Excellent response!There are parrot rescue groups all over the world. There are at least 4 in GA. There is likely to be one close to you.
The chances of finding a free one that someone would be willing to deliver to you are slim and none. If they would be willing to do so, they would require you have proper housing. What are the dimensions of the cage it would be kept in? Do you have an area outside the cage for recreation and play time?
Do you know anything about keeping parrots?
Properly keeping most parrots requires at least one huge cage which can be $1000 or more. Can you do that?
Can you commit to keeping a bird with the constant care it needs for 50 or more years?
If you can't commit to that long term care, forget it.
The reason there are so may rescue groups is that so few people know how to properly care for them and give them up. Every time they lose their home, they become more psychotic. They will need a professional behavior consultant (about $125 per hour) in order to get over their psychoses. Some can't be fixed. We had several rescues that would attack any human they could reach. We had one that would pluck every feather on its body.
Getting a rescue parrot presents many more problems. The reason is that most people aren't prepared for that long term care. Most parrots mate for life. If it is a single parrot, you are their mate. They go crazy if they are rehomed. I'm affiliated with several rescue groups. I worked at a macaw breeding and rescue program in the tropics with over 400 Scarlet and Great Green Macaws. Many were rescues from homes and makeshift zoos as well as many bred there for eventual release into the wild.
People really shouldn't own these majestic birds. Most people aren't willing to give them the size housing they need and are unwilling to spend the time with them they need, every day of their life. Then they will outlive a human and then outlive their children. We had a breeding pair of scarlets that were over 90 years old.
