Perhaps the type of instruction you want from the pet stores is something like this: "You may have trouble with this bird (dog, cat) later on. Here's everything that could possibly go wrong." The animal organizations you support are trying to limit the public's right to purchase animals because they feel we are inherently incompetent, therefore they desire to limit our access to the marketplace with legislation and lawsuits.
If Petco or Petsmart told people the truth about what's required to keep a large parrot in captivity, they'd never sell any birds.
Without knowing which animal organizations you're talking about it's impossible for me to address what you write. I will say that I support organizations that seek to limit or eliminate altogether the mass breeding and sales of large parrots like amazons, greys, macaws and cockatoos. These birds are wild animals and do not belong in most people's homes because most people do not have the education or inclination to provide for the bird's needs.
