Wellness Wednesday: A Peek Inside a Parrot’s Mouth Safely!
Parrots are naturally mouthy, using their beaks and tongues to explore their world. This week, let’s dive into the fascinating structure of a parrot’s mouth, or *oropharynx*. This vital area includes the tongue, glottis, choana, palate, salivary glands, esophagus, pharyngotympanic tube openings, and laryngeal mound.
The parrot’s tongue is unique—it contains a bone for added strength and dexterity. Adapted for collecting, manipulating, and swallowing food, the tongue works seamlessly with the glottis (opening to the windpipe) and the laryngeal mound at its base. While mammals use their larynx for vocalization, birds rely on their syrinx, located deeper in the respiratory system, to produce their sounds.
On the roof of a parrot's mouth is the choana, a slit-like structure connecting the nostrils to the windpipe. When a parrot closes its mouth, the glottis fits snugly into the choanal slit, forming a closed airway—a remarkable adaptation! Surrounding the choana are tiny projections called papillae, which often point toward the back of the throat. Behind the choanal slit is the infundibular cleft, the opening to the middle ears.
Taste buds in parrots are located near the choana and the laryngeal mound, allowing them to enjoy a range of flavors.
During veterinary check-ups, examining the oropharynx is crucial. Signs such as swollen choana, blunted papillae, red infundibular clefts, or mucus can indicate malnutrition, vitamin A deficiency, infections, or even internal papillomatous disease. Lesions, such as wart-like papillomas, may also appear and warrant investigation.
Parrots’ oropharynx coloring varies by species and can help distinguish normal from abnormal. For instance, a blue and gold macaw may have a uniformly black throat, but pink patches could signal disease—or simply be natural variation.
At Papayago Rescue House, we check each bird’s oropharynx upon intake and routinely monitor for changes. With regular observation, you’ll learn to recognize healthy baselines and spot potential issues early. Let’s keep our feathered friends thriving!
