Quaker rolling his tongue.

My Quaker Parrot, Rango, makes strange movements with his tongue. It seems he does this mainly in the morning. It is almost like he is sticking it out, but more to the side vs. the front. Like I said I don't notice this behavior in the evening. He has water available all the time, so his mouth shouldn't be dry. Is this a normal behavior?
