Overview
The size and structure of the avian tongue varies between species. It is related to functional requirements.
Structure and Function
The avian tongue is narrow, pointed and contains little intrinsic muscle. The enteroglossal bone is present consisting of bone and cartilage with medullary spaces containing red marrow. It is supported by the lingual process of the hyoid bone and rudimentary lingual muscles. It contains striated muslce fibres.
Species Differences
Parrots use their muscular tongue to lap water and to produce human sounds (see here).
