Hi, I have a rehomed male U2 who does a wierd thing. When we bring him into the clubroom with us and he sits on the back of the sofa or my arm at the computer he sticks his tongue way out then proceeds to form saliva or spit bubbles in his mouth. He moves them very fast from front to back of his bill. He is not nervous because he also plays with us. He does not do this in his cage or when he is out on his cage. He never spits anything out you can just see the saliva turning white as he works it.
Foxersartist a while back I also posted to you about the lg playstand you have made of branches/wood. I can't remember where I posted to see if you answered. Did you buy or make this?

Several of my Too's play with their own spit. Maxie likes to string it in her mouth.
Silly birds! LOL!
