Conures are very very noisy for their size well the aratinga species are. The pyrrhura species are somewhat quieter. Does your wife work? Cockatoos are love sponges and need A LOT OF ATTENTION or else they may develop bad habits (feather picking, screaming). I would love to have a African Gray. They are considered the smartest of the parrot species. If you are looking for a big bird in a small package look into Caiques. Their antics are absolutely adoarble not to mention they are pretty too. Someone mentioned a Senegal. I raised these for years. They are awesome little birds and make hardly any noise at all. You listed many breeds in the poll and it would be impossible for me to choose. Good luck making your decision
