Sounds like beak-grinding to me, but it depends on what is going on when she is doing it, and when it is that she does it...Can't really tell what is going-on when she's doing this, but if it's while she is hanging-out with her person/people, or it's in the evening before bedtime, then it's most-definitely beak-grinding, and it simply means that she's content and very happy...
