Likely knocking on the glass or other objects in the tank

If its the odd scale that you are finding, as Hendre said, it could be from her fighting with the parrot or bumping herself

However, just pay attention to her whole body and make sure the rest of the scales all look neatly against the body and that you dont see any signs of her scales looking as if they are lifting.

If the rest of the scales on her body look perfect, then dont worry too much but keep an eye that the fighting is not getting worse
