I forgot about Jenday. Yes, I heard that they are comparable to Suns. But I don't have experience with them. I don't think their calls are loud as a Sun's call though. I don't know if they're as hyperactive too.
I'm totally biased towards all varieties of green cheeks. My little cinnamon is so adorable, and turquoise green-cheeks melt my heart. But I love all conures!
My blue crown is not loud at all. I think of him as calm, cool and collected, but he IS a chatterbox. Even when we are in the car and he is in his carrier in the back seat, if I call him, he answers me and will yell "you're a good boy' about 2 or 3 times, for good measure, LOL. He makes mostly cooing, oohs and aahs, and says a few words and phrases. He also chatters in his conure talk, but totally takes the tone of a human conversation. It is so cute.
What?? No votes for Duskies?? What's up with that? Duskies are wonderful companion birds packed to the brim with personality. Hence, I'm voting for Duskies!
