Well everybody is going for the grey, but I have to speak up a little bit on the part of the Sun Conure (being as I have one). If you are looking for a really playful clown, like a cuddly bird, don't mind a loud bird at times, don't mind a little attitude at times (they can for sure be nippy) then a Sun might just be for you. However, on the grey side (I also have one of those, except mine is a Congo) They are EXTREMELY intelligent, most of the time talk like you can't believe (and really seem to understand what they are saying), don't seem to like cuddling but usually love scratches, are somewhat playful however not nearly as much as the Sun in my experience. Mine is much more serious than my Sun. Also Grey's are usually one person birds (and you never know who it is they will choose) Mine chose my husband even though I am the one that takes care of her all of the time.They can also have a little attitude at time. So with all of that being said (which is just my opinion from how my parrots are), I don't think you can go wrong with either parrot. Just as long as you know what you are getting in to with each. They are really completely different in a lot of ways but both have wonderful things about them. But I guess you can tell by the response Grey's are usually more popular. Sun's scare off a lot of people because of their very loud call. Any way that is my 2cents. Good luck with your decision. I have to say I really love both Suns and Greys!!!
