Most large pet stores have contact with good breeders who are ethical and have their parrots' best interests at heart. Find out through them if they reqire that you use them as "middleman".
Decide what kind of parrot you want to bring into your family. Macaw? Lots of sizes and colors and temperaments. Conures? Little, peppy, and adorable. Cockatoos? very needy in the hugs and loves department. If you can't spend a lot of time interacting with a cockatoo, it's better to get a different breed.
Talkers are Amazons and African Greys (although all will talk to a point). Amazons are green, with varying colors around head and neck. African Greys have two races: The Congo, which is a little larger, has a black beak, and bright scarlet tail feathers. The Timneh is a bit smaller, has ivory color in its beak, and the feathers are more of a maroon color.
The large birds are expensive. AG's run around $1,000. I don't know how much Macaws are, but I presume they are at least that much, if not more.
Be sure you are READY for a large bird in the house. They require considerable space. They are also very messy eaters, leaving shells and crumbs everywhere. They can also be destructive, as those beaks are very strong. So you may want to ponder whether to leave your bird at large or confine it. If you decide to confine it, be sure you get it the biggest cage you can afford, and plan to upgrade every few years.
Large birds live a long time. Their lifespan is roughly the same as a human's, so if you decide to take a parrot, decide also to whom you plan to leave it in your will should it survive you.
