Thank you guys so much for the responses! Especially you MissLissa! That was extremely informative. What would be a good treat food to use when reinforcing positive behaviors?

Also, we have a rose breasted cockatoo currently at my job who is fantastically sweet when he first comes out of his cage, but then can get very bitey. He loves to be cuddled and held and kissed (by select females mind you...not so much men, and not all women. Just the girls I work with.) But then, out of the blue, he'll start reaching for, and biting people. Hands, ears, whatever is closest at the time. What is the best way to deter that activity with a bird who loves to be cuddled? Put him back in his cage or on his play area? That sounds like a "time out" to me. But that is what we have been doing. I don't want to make that mistake any more if it is a mistake, and I certainly don't want to make it with my own future bird! He is also very bitey if he is eating anything or chewing on anything and someone reaches for him. Any advice on that?

Another thing, I have read that the pineapple conure morph is generally quieter and sweeter than the regular green cheek. Any merit to this? I've read it in several places, and have experienced it personally having one pineapple and one green cheek at the sister store. The pineapple is very quiet and affectionate, while the other bird babbles alot and screams more often. I was just curious what your thoughts were on that little tidbit also, as it is one of the many reasons I was intending to purchase a pineapple morph over the regular. Not to mention the gorgeous plumage.
