What are the bones in a bird’s skull called?

Why do birds have different types of skulls?

Birds show independent movement of the skull bones known as cranial kinesis. Cranial kinesis in birds occurs in several forms, but all of the different varieties are all made possible by the anatomy of the skull. Animals with large, overlapping bones (including the ancestors of modern birds) have akinetic (non-kinetic) skulls.

How do birds move their beaks without the skull?

In all birds there is a series of smaller bones behind the lower and upper beaks which allow them to move the beak independently of the skull. These include the palatine, quadrate and pterygoid bones and the jugal arches.

The most obvious thing that tells you you’re looking at the skull of a bird and not a mammal is the beak.

In birds, the equivalent processes are much smaller. Also, the shape of the vertebrae themselves allows for a greater range of motion. This allows birds to move their heads freely for feeding and flying and to reach any part of the body with the beak for grooming.
