Hi everyon, I was hoping I would get some help. For the past two weeks I have noticed white spot on the side of my cockatiels tongue that comes and goes. The spot is usually in one place on the side of the tongue, it appears every few days and the goes away in a day or two and comes back. I was thinking this might be oral yeast but is it normal for the spots to come and go away on itself and then come back and go away? I would appreciate it if anyone has any idea as to what this might be.
