Richard StallmanIf you can find a host for me that has a friendly parrot, I will be very very gladโฆ DON'T buy a parrot figuring that it will be a fun surprise for me. To acquire a parrot is a major decision: it is likely to outlive you. If you don't know how to treat the parrot, it could be emotionally scarred and spend many decades feeling frightened and unhappy. If you buy a captured wild parrot, you will promote a cruel and devastating practice, and the parrot will be emotionally scarred before you get it. Meeting that sad animal is not an agreeable surprise.
