A Northern Gannet poses during my Gannets Galore Workshop for a portrait with its mouth wide open, showing off its nasofrontal hinge.
That’s not an accidental break in its beak! At the base of the upper mandible, a thin sheet of nasal bone is attached to the skull at the nasofrontal hinge, which gives mobility to the upper mandible, allowing it to move upward and downward.
