Ahhh . . . I used to have a couple of parrots and I went to a bird expo once, and had the same feelings. I really try to buy rescue/used animals. I went there to get a good deal on some bird accessories, but it was sad to see terrified parrots being stuffed into small carry cages without much screening to what kind of home they were going to.
(My two former parrots were ill-behaved rescues who turned into wonderful companions. I had to give them up when I left a bad situation, but I placed them in the care of a parrot rescue organization along with a donation-- both were placed in great homes and I was in contact with the owners for about a year after the adoptions to answer questions they had.)
