I completely agree with the others, and I think you posted this on Talk Budgies? So as I replied there I won't repeat myself lol.
Daisy - a lot of the Macaws in zoos are actually rescues, where I work the two we have one of those was a rescue and the other is on full time loan from the owner. Where I used to work hey have 4 Parrots, 2 B&G Macaws, a Conure and Rocky and they were all rescues.
We do have specialist animal sanctuaries they just aren't as well known over here, theres a huge one up in Scotland, theres Wingz Bird Sanctuary down south somewhere, there's of course Birdline.
If you browse the ads it's heartbreaking how many are for sale, and you soon notice a pattern emerge with the ages of these birds, very few are older birds who have settled past their hormonal stage, most are in the middle of it as people don't realise what they are getting into as it's so cute and cuddly when it''s a baby
Sheila - I don't think people should stop breeding Macaws, we need a good solid foundation to fall back on when the wild birds are poached and killed too far to make a natural recovery, we do however need to stop indiscrimnate breeding for the sake of money, people need to home check when selling such long lived animals, breeders should be responsible enough to take that bird back the moment the new family no longer want/ or can no longer care for it rather than it just being passed from pillar to post. Without the captive breeding of a lot of species we that are threatened in the wild we would have no hope of recovering the population.
My dream is to someday open my own bird sanctuary and run a conservation centre alongside it to not only take in unwanted/ abused/ abandoned birds but also to help educate people and preserve the species that us humans are responsible for destroying.
