Bonebirds are a lower classification of Boneheads, a group of end creatures possessing exoskeletal plating around their heads, although it is present on other parts of the body in some species. Bonebirds feast on hard nuts and seeds, using their vertical beak-like mouthparts to crush them before consumption. Bonebirds are capable of flight, gliding on thin pieces of tissue located on their sides and back end.
