Bird’s Tongue

Birds have many different types, shapes, and sizes of tongues, depending upon the species, and what they eat. Birds don’t have teeth, and that means that the tongue is very important. 

A human tongue is a muscle. A bird tongue is a muscle too, but tougher and harder than a human tongue. Birds have five bones in their tongue. These bones are known as the hyoid apparatus. The five bones are: paraglossals, basihyale, urohyale, ceratobranchiate, and epibranchiate.

Emu Eyes and Nictating Membranes

The Australian Emu (Dromaius novaehollandiae) has protective nictating membranes on its eyes. The membrane over each eye protects them from dust.

A nictating membrane is a transparent or translucent eyelid. The eyelid membrane not only protects the eye from dust, it also moistens the eye and cleans away any dust or dirt. This is because the emu lives in dry, dusty areas of Australia.

Nictating means blinking. The eye membrane is called a third eyelid, or a haw, or a plica semilunaris, or a membrana nictitans.
