A Parrot’s Upper Beak Can Move

In most animals, the upper jaw is fixed. In parrots, it connects to the skull through a mobile joint and can lift and move forward relative to it; lower-jaw movement is controlled separately. This mobility, called prokinesis, helps parrots when feeding, and they also use the beak for support while climbing. The movements interact within a complex system, so “independently” does not mean the two parts of the beak are mechanically unrelated. The illustration is AI-generated, not a documentary image.
