Regarding the topic of paying a higher price for a bird ... I agree that a higher price can lead to the bird placed in a better home, because the price of parrots made me do a lot of research to make sure I could take care of one before I would buy. One of the deciding factors for me was that we are lucky enough to have an avian vet nearby. Knowing that, I felt more confident that we could care for her. I considered it very carefully. My carefulness was based on two factors, once I adopt an animal, I like to keep it for like, and secondly, the price, (not only of Emily, but the cage, supplies, vet bills.) So, price made me a more careful consumer.
However, price doesn't always do that for people. So, it's just one factor. And, I agree, responsibility is also a factor. I would be careful when considering buying another cat, when cats are inexpensive compared to parrots and easy to take care of.
Finally, I know nothing about bird auctions, but it does seem that the person in question bought the parrot because he saw it as a valuable, rather than a pet. We don't know. I just wish that more people would take their time and really think about all the factors when they get a bird, no matter where they get it from.
