Quakers are all of the above and much more.
After talking to him I called a bird farm in Florida and bought 6 pairs of surgically sexed Quakers. Breeding Quakers has been one of the most rewarding thing I have done with birds of any kind. What a happy bunch of baby birds. Since then I have learned that they are excellent talkers, they are sweet and affectionate. And they are one of the most intelligent birds I have ever come across.
