Thank you all for your comments. Louie is certainly a sweetheart. He can touch me, I just can't touch him. He is fully flighted and has never been clipped so he has the upper-hand so to speak as he can leave any old time he wants! He enjoys sitting on the back of my couch and preening my hair. As long as I do not try to touch him and just let him preen away, he is happy as a lark. Ray, Louie is only three, I doubt he is hormonal as he is as sweet as molasses just untouchable. He has many times taken my finger into his beak with a "no, no, no touchy" attitude but never bitten down.
