Sticking tongue out and rubbing it

My Quaker Parrot who is almost 2 (we have had her since 11 weeks) started sticking her tongue out to the side this morning over and over. She also is sometimes sticking her tongue out and rubbing it. She is eating, drinking, pooping and other than the tongue thing acting normally. She has never done this before and I'd like to know if this is a behavior or if something can be going on with her.

I called the vet and since it's Saturday they are closed. I do plan on calling again when they open and see what she thinks but in the meantime I'd love to hear your thoughts. Thank you for your time.
