Good day! Can anyone tell what my parrot(female, 10 yo) is trying to do with his beak(on the video). She can do it for a very long time, but it doesn't look like beak grinding in relaxed state. It seems she is doing something with full concentration, as if trying to sharpen her lower jaw?! So it lasts for 2-3 month... Any ideas what happens??? Thank you.
